comment172 Comments

The Asian Longhorned Beetle (ALB) is a wood-boring insect native to China and the Korean Peninsula, posing a significant threat to hardwood trees in the United States. Belonging to the Cerambycidae family, this invasive species is known to feed on a variety of trees, eventually killing them.

Early identification and eradication are critical, as there is currently no cure for the damage caused by ALB. It’s essential to be familiar with the signs of an infestation; look for exit holes left by the beetles after chewing their way out of the tree during warmer months, alongside other distinctive signs of damage.

To help prevent the spread of the Asian Longhorned Beetle, it’s necessary to adhere to quarantine measures in your area and follow guidelines to leave Hungry Pests behind. If you spot a beetle or suspect your tree is infested, report it to the appropriate authorities immediately.

Overview of Longhorn Beetles

Classification and Scientific Name

Longhorn Beetles belong to the family Cerambycidae, which includes a variety of species with unique features. They are also commonly referred to as “long-horned beetles” or “longicorns.”

Distinctive Features

Some key features of Longhorn Beetles are:

  • Elongated and cylindrical body shape
  • Antennae at least half the length of the body, sometimes much longer
  • Often smooth, streamlined, and tapering toward the back

Size and Appearance

Longhorn Beetles have a diverse range of size and appearance. Examples include:

  • Asian Longhorned Beetle: 1 to 1.5 inches in length, black body with small white spots, black and white banded antennae
  • Others: Drab black, gray, or brown colors or mimicking wasps with black and yellow/orange banded patterns

Worldwide Distribution

These beetles can be found all over the world but are native to regions like China and the Korean Peninsula. The varied species within the Cerambycidae family occupy different habitats and have adapted to their surroundings.

Here is a comparison table of different Longhorn Beetle species and their characteristics:

Species Size Color Antennae Region/Habitat
Asian Longhorned Beetle 1-1.5 inch Black with white spots Black and white Asia
Mimicking Wasp Longhorn Varies Banded black and orange Varies Other Regions
Drab Colored Longhorn Varies Black, gray, or brown Varies Other Regions

Life Cycle and Habits

Eggs and Larvae

Valley elderberry longhorn beetles, like other longhorn beetles, start their life cycle as eggs1. A female beetle lays the eggs on the leaves and stems of their preferred host plant, the elderberry. The eggs then hatch into larvae that feed on the plant tissue2.

  • The larvae stage is known for consuming the plant’s tissue and sapwood3.
  • They damage living trees, ultimately affecting their overall health.

Adult Behavior

Adult longhorn beetles emerge from their pupal stage usually around March to June4. These adults continue to feed on their host plants, targeting the leaves, flowers, and occasionally twigs5. Mating and reproduction take place during this active period.

  • Adult beetles have unique features, such as long antennae and striking color patterns6.
  • They can fly but are commonly seen on their host plants.

Feeding and Diet

Longhorn beetles feed on various parts of their host plants, depending on their life stage7. Here is a comparison of the feeding habits of larvae and adult beetles:

Life Stage Feeding Habits
Larvae Plant tissue, sapwood
Adult Leaves, flowers, twigs
  • The majority of their diet comes from the plants they infest.
  • Living trees are greatly affected by their feeding habits.

Habitat and Host Plants

Forests and Woodlands

Longhorn beetles are usually found in forests and woodlands across various continents such as North America, South America, Asia, Europe, and Africa. Their larvae, called roundheaded borers, feed on and inhabit the insides of trees, generally preferring dying, freshly cut, or recently-killed trees for their development.

Popular Host Trees

Longhorn beetles have a wide range of host trees. For instance, the Asian Longhorned Beetle favors healthy trees belonging to 12 genera, with maple (Acer spp.) being a primary preference. Other commonly attacked genera include:

  • Horsechestnut (Aesculus spp.)
  • Birch (Betula spp.)
  • Willow (Salix spp.)
  • Elm
  • Ash
  • Poplar

Comparison Table:

Host Trees Beetle Species
Maple (Acer) Asian Longhorned Beetle, Valley Elderberry Longhorned Beetle
Horsechestnut Asian Longhorned Beetle
Birch Asian Longhorned Beetle
Willow Asian Longhorned Beetle
Elm Longhorned Beetles
Ash Longhorned Beetles
Poplar Longhorned Beetles

It is essential to know the popular host trees to identify potential signs of infestation and act accordingly to protect these trees from damage.

Varieties and Subfamilies

The Longhorn Beetles, also known as Cerambycidae, are a diverse group of beetles with more than 20,000 species worldwide. They are divided into several subfamilies, some of which include:

  • Cerambycinae
  • Lamiinae
  • Dorcasominae
  • Lepturinae
  • Necydalinae
  • Parandrinae
  • Prioninae
  • Spondylidinae

Well-Known Species

Some well-known species of Longhorn Beetles are:

  • Acrocinus longimanus: Commonly known as the Harlequin Beetle, this species can be found in Central and South America. They are known for their striking red, black, and yellow patterns.
  • Anoplophora chinensis: Also known as the Asian Longhorned Beetle, this species is native to China but has caused damage to forests in North America and Europe. They are black with white spots, and have long, striped antennae.

Here is a comparison table of these two species:

Feature Acrocinus longimanus (Harlequin Beetle) Anoplophora chinensis (Asian Longhorned Beetle)
Size 50-80 mm 20-35 mm
Color Red, black, and yellow patterns Black with white spots
Distribution Central and South America Native to China, invasive in North America and Europe

Each subfamily of Longhorn Beetles has unique characteristics, but they generally have the following features:

  • Long antennae, often longer than their body
  • Elongated, cylindrical body shape
  • Wood-boring larvae
  • Attraction to dying or freshly cut trees

These diverse beetles play an important role in their ecosystems, from breaking down wood in forests to acting as pollinators for various plant species.

Invasive Species and Their Impact

Asian Longhorned Beetle

The Asian Longhorned Beetle is an invasive species that threatens hardwood forests, urban gardens, and economically crucial trees like maple, willow, birch, and elm. Native to China and Korea, it has been found in North American cities like New York and Toronto. The beetle’s damage comes from tunneling through tree trunks, compromising tree strength.

Key features of Asian Longhorned Beetle:

  • Black with white speckles
  • Long antennae with white bands
  • Body length: 1-1.5 inches

Anoplophora Glabripennis

Anoplophora glabripennis is another name for the Asian Longhorned Beetle. This invasive species’ infestation can drastically impact local ecosystems and economy.

Infestation impacts:

  • Decreased tree survival rates
  • Damage to hardwood trees
  • Threats to the lumber industry

Eradication programs:

  • Quarantines of affected areas
  • Removal and destruction of infested trees
  • Chemical treatments for control

Comparison table of infestation effects in New York and California:

Location Damage to trees Area/type affected Eradication efforts
New York High Urban parks Quarantine/Removal
California Moderate Hardwood forests Quarantine/Treatment

Detection and Identification

Identifying Features

The Longhorn Beetle is a diverse family of beetles, with many species displaying unique features. Common characteristics include:

  • Elongated and cylindrical body
  • Antennae at least half the length of the body, sometimes much longer
  • Coloration varies from drab black, gray, or brown, to banded patterns of black and yellow or other colors, such as seen in the Black and Yellow Longhorn (Rhagium bifasciatum)

For example, the Valley Elderberry Longhorn Beetle is a medium-sized, red and dark green insect, approximately 0.8 inches long, with females larger than males.

Finding Exit Holes

Exit holes can be indicative of beetle presence, particularly during warmer months when adult beetles chew their way out of wood. These holes can be found on branches, stumps, or ports on infested trees. Entomologists and scientists often use exit holes to help identify infestations of beetle species, such as the Asian Longhorned Beetle.

Signs of Infestation

Be vigilant and look for signs of beetle infestations on leaves and wood. Common signs include:

  • Exit holes, as mentioned earlier
  • Roundheaded borers, which are woodboring larvae of many longhorned beetles
  • Frass or sawdust from burrowing beetle grubs
  • Damaged bark or branches

Some natural predators and animals can help control beetle populations. However, it is crucial to report any possible infestations for further investigation by experts.

Ecological and Economic Importance

Forest and Timber Damage

The Longhorn Beetle is known for causing damage to various tree species, such as ash and poplar trees. Adult beetles and their larvae feed on the wood and bark, weakening the trees and making them susceptible to diseases and other pests. Some examples of damage caused by Longhorn Beetles include:

  • Weakening of timber, reducing its commercial value
  • Creating entry points for harmful pathogens

Control and Management Strategies

There are a few different methods for managing Longhorn Beetle infestations. Some common strategies include:

Biological Control

  • Release of natural predators, such as birds and insects

Chemical Control

  • Insecticides applied to affected trees or areas

Physical Control

  • Removal of infested trees

However, each method comes with its own set of pros and cons. Some factors to consider when selecting a control strategy include effectiveness, impact on non-target species, and cost.

Control Method Pros Cons
Biological Eco-friendly, low risk to other species May be slow acting
Chemical Fast-acting, effective Harmful to other species and the environment
Physical Removes source of infestation Labor-intensive, may not be feasible for large-scale infestations

In summary, Longhorn Beetles pose a threat to forests and timber value. It is essential to implement prompt and effective management strategies to minimize their impact and preserve the health of our ecosystems.

Letter 1 – Round Headed Borer Larva


grub in the wood
Location: houston, texas
May 2, 2011 10:24 am
I had a water oak that died a year ago. I chopped it down and was splitting the wood for firewood. This grub fell out. It was burrowed in the middle of the log and is about 2 and half inches long. What is it, and could it be the reason the tree died?
Signature: shawn

Round Headed Borer Larva

Hi Shawn,
This is the larva of a beetle in the family Cerambycidae, the Longhorned Borers.  The Larvae are known as Round Headed Borers.  You can compare your images to those posted to BugGuide.  The BugGuide information page indicates this about food:  “Larval habits: Most species feed within dead, dying or even decaying wood, but some taxa can use living plant tissue. Girdlers (adults of the Onciderini, larvae of genera in the tribes Methiini, Hesperophanini and Elaphidiini) sever living branches or twigs, with the larvae developing within the nutrient-rich distal portion. The larvae of a few species move freely through the soil, feeding externally upon roots or tunneling up under the root crown.”  BugGuide goes on to reveal this about the life cycle:  “The life spans in temperate regions typically range from 1 to 3 years, but cycles of 2-3 months to decades have been documented. Most of the lifetime is spent in the larval stage; the adults usually emerge, disperse, reproduce, and die within a few days to months. Cellulose digestion appears to be aided primarily by enzymes rather than symbiotic microorganisms. In many cases, Cerambycidae are primary borers, providing a vital ‘first step’ in the biorecycling of wood.”  The other major family of wood boring beetles are the Metallic Wood Borers in the family Buprestidae.  The Buprestid Larvae are known as Flat Headed Borers.  You may compare the Round Headed Borers to the Flat Headed Borers by looking at these images on BugGuide.  Except in rare cases, Borers feed on dead and dying wood and they do not infest the wood of healthy trees, so we doubt that the death of the tree was caused by this Round Headed Borer.

Letter 2 – Longicorn from South Africa

Hi, Hope you can help me in sunny South Africa. Our Leapard Tree (caesalpinia ferrea) all of a sudden started to die, only the one, and on this one we found a bunch of the attached bugs!, are these a type of borer?. I hope there little guys are not the reason for my trees lack want for life…
Signature: A little desperate

Longhorned Borer Beetle

Dear A little desperate,
Your suspicions that this is a type of borer beetle are correct.  This is one of the members of the Longhorned Borer or Longicorn Family Cerambycidae.  We wanted to try to identify the species, and our initial search brought us to a photo of
Ceroplesis capensis on the Biodiversity Explorer website.  It looks similar to your individual, but since Ceroplesis capensis has four red stripes, it is most likely a different species.  We searched the genus name and found an image from a South African Postage Stamp that is named Ceroplesis militaris, and it looks very similar to your individual.

South African Postage Stamp

The iSpot website also has an image identified as a Cape Longhorn Beetle in the genus Ceroplesis that looks very similar to your individual.  We are relatively confident we have the species correct, and since this is definitely a Longhorn Borer Beetle, it might have been responsible for the demise of your tree.

Hi Kathy,
This beautiful beetle is a Banded Alder Borer, and down south it is known as the California Laurel Borer, so since you are at the northern border, it would stand to reason that you have your own gene pool up north.  Unless DNA analysis is performed, we will probably never know if your beetle is a distinct subspecies, in which case it might be called an Idaho Laurel Borer.

Letter 5 – Poinciana Longicorns from Australia


Root Borer from AustraliaD

Dear bug man
I found these two bugs flying around. I think they are a type of root borer. What do you think? And do they bite?
Signature: Jess

Poinciana Longicorn

Hi Jess,
We believe we have correctly identified your Prionids, commonly called Root Borers, as the Poinciana Longicorn,
Agrianome spinicollis, based on a photo posted to the Queensland Museum website.  That site indicates:  “This species is found in rainforest and open forest in eastern Australia. It is common in Queensland and New South Wales and also occurs on Lord Howe Island. The larvae are huge white grubs found in rotten wood, especially dead Poinciana or fig trees. It is an important pest of pecan trees. The large adults sometimes blunder into house lights.”  Graeme’s Insects of Townsville, Australia also has some nice photos of the Poinciana Longicorn.  We found an online reference to an overlooked publication on Australian insects that has this information:
“The information provided noted that the large white grubs (larvae) of A. spinicollis tunnel into
trees and feed upon the wood and that large oval (exit) holes are often observed on the bark. The
species usually attacks dead timber but beetles are occasionally found in living trees feeding upon
the green wood (Anon., 1934). As they burrow through the wood, they close up the tunnel behind
them with the excreta being pressed into a hard mass with the posterior abdominal segment
(Anon., 1934). The eggs are placed upon the bark or wood of the tree; the tiny larvae hatch from
the eggs and immediately bore into the wood tissue; even at this stage, the mandibles are hard and
strong (Anon., 1934). During September and October the mature larvae cease feeding and a
gradual change occurs within their bodies; the larva contracts, the skin becomes loose and the
body becomes soft and flabby; the larva becomes a pre-pupa which lasts about 2 weeks (Anon.,
1934). The skin then splits along the back of the head and thorax and is gradually worked down
the length of the body by a series of convulsive movements and then cast off, revealing a pearly
white pupa (Anon., 1934). The pupa rests in its pupal chamber for about 2 months; after the
final metamorphosis occurs, the pupal skin is cast off and the adult beetle emerges and remains in
the wood for a few days before eating its way out of the tree (Anon., 1934).

Regarding your bite question, Prionids have strong mandibles that they need to chew their way out of their pupal chambers when they mature.  Large Prionids can deliver a painful bite that can draw blood, and they should be handled with caution.

Letter 7 – Unknown Longicorn from Singapore


Bug with Striped feelers

I found this bug on one of my building structure in Singapore. Occasionally, the brown patch on the back will lift up to reveal wings. The feelers are very long. Do you know what bug this is?

Unknown Longicorn

Hi Stanley,
This is a Long Horned Borer Beetle or Longicorn in the family Cerambycidae, but we are uncertain of the species.  Perhaps one of our readers will attempt an identification while we are at work furthering the education of others.

Karl has an answer
Hi Daniel and Stanley:
I think this longicorn is probably Coptops leucostictica (Cerambycidae: Lamiinae:  Mesosini). I am fairly certain that is the genus, with an outside chance that it may be Mesosa. There is an excellent website called “Longhorned Beetles of Singapore” that you can explore, or go directly to a very nice photo of C. leucostictica. The species is found throughout mainland southeast Asia, Singapore and west to India. Regards.

Dear Alan,
This is a Longicorn or Longhorned Borer Beetle in the family Cerambycidae.  Though they are not poisonous, larger individuals do have very strong mandibles, and some species may draw blood if they bite.  The closest match we could find on BugGuide is Achryson surinamum, but we are not certain that is a correct identification.  We will try to contact Arthur Evans, an expert in Beetles, for assistance.

Longicorn Beetle

Hi Paul,
We agree that this is some species of Longicorn in the family Cerambycidae, possibly in the subfamily Prioninae. We would think a specimen this spectacular and distinctive would be easy to identify, but an identification is proving to be elusive for us. We found a new Australian website known as Insectographs, but could not find your beetle on it. We searched through all the Cerambycids on the Csiro Entomology page and the only one that looks close is the Feather-Horned Yellow Box Borer, Distichocera macleayi, but it is a mounted specimen. This may be a related species in the same genus, and we would not rule out the possibility that this is an introduced exotic specimen. We don’t feel confident with the Feather-Horned Yellow Box Borer identification unless someone else can write in to substantiate.

Hi Abel,
This is one of the Longhorned Borer Beetles in the family Cerambycidae.  It looks close to the Rustic Borer,
Xylotrechus colonus, that is posted on BugGuide.  According to BugGuide:”Larvae feed under the bark (occasionally in the bark) of hickory and other hardwoods, also pine” and  “Often attracted to UV lights.”  Many Cerambycids are found in homes because they were inadvertently brought in with the firewood by the owner or tenant while the beetles were in the dormant stage.  The heat of the home causes them to emerge.  They will not infest your home.

Hi Alan,
We often have trouble identifying Hawaiian insects for two reasons.  One is that there doesn’t tend to be much available, easily accessible information online.  The second reason is that so many introduced species are found on the islands.  We quickly identified this Monkeypod Round-Headed Borer, Xystrocera globosa,
on a Insects of Hawaii website.  There wasn’t much information, but it was indicated that it was non-native.  We then searched the scientific name and found an article on Five New Invasive Species of Longhorn Beetles in Israel.  There we learned that “X. globosa originatesfrom southeast Asia and is widely distributed inthe Oriental Region (East Pakistan, India [includ-ing Andaman Islands], Indonesia [Java, Suma-tra, Celebes], Sri Lanka, Myanmar, Thailand,Laos, Malaysia, Philippines, Seychelles), Ocea-nia (Australia [Northern Territory], New Guinea)(1,15), Hawaiian Islands (1,6)), Madagascan Re-gion (Madagascar, Rodriguez, Mauritius) (1),Caribbean (Puerto Rico) (1,6), and subtropicalareas of the Palaearctic Region (Arabia, Egypt(1), Japan (1,18), Korea, Taiwan (1)).”

Thanks!  I had searched for hours on a couple of large insect ID sites, but never thought to look locally…
Makes sense, too, because there are lots of monkeypod trees surrounding Ka’u hospital.

US and, more recently, in the Pacific Northwest.”  According to iNaturalist:  “Larvae develop in and under the bark of various deciduous tree species, causing damage. Larvae pupate in the spring. The beetle’s life cycle lasts one year in central and southern parts, and two years in northern climes.”  It is described on Nature Spot as being:  “Length 8 to 13mm. Very variable in colour from golden brown, through reddish to a deep blue-black. A common form has the thorax reddish and the elytra deep blue.”

Beetle #1 is a Scarab in the family Scarabidae, but we do not know the species.  Beetle #3 is a Longicorn in the family Cerambycidae, but we do not know the species.  Beetle #2 is striking in color and markings, but we cannot determine its family.  It somewhat resembles the Pleasing Fungus Beetles in the family Erotylidae, but your photo does not reveal enough of the physical characteristics to be certain.

Longicorn: Xylorhiza adusta

Dear Dan,
This is a positively gorgeous Longicorn or Longhorned Borer Beetle in the family Cerambycidae.  We believe we have correctly identified it as Xylorhiza adusta thanks to images on Singapore Fauna where it states:  “It has a wide distribution in Asia, from India to China and down to Sumatra. Known host plants include Beautyberry trees (
Callicarpa arborea and C. macrophylla); plant from the mint family (Premna pyramidata); Viburnum odoratissimum and Wrightia tinctoria: both a kind of small shrubby tree.”  We also found images on FlickR and The Worldwide Cerambycidae Photo Gallery.

Thank you for identifying the insect. Many did not know its type. Now many have a new respect for this living being.

Your beetle is a Longhorned Borer Beetle in the family Cerambycidae, and just yesterday we spent about an hour attempting to identify another member of the family from Thailand,
Cyriopalus wallacei, so we knew the best place to start searching for the identity of your individual.  We went straight to the Worldwide Cerambycoidea Photo Gallery and filtered individuals from Thailand, and then on page 3 we found the Common Tuft Bearing Longhorn, Aristobia horridula.

Letter 20 – Longhorned Borer From Costa Rica


Beetle ID

Trying to get an ID on this beetle from Costa Rica.
I’m not very familiar with my bugs and wouldn’t know where to start looking.
So here I am.
Osa Peninsula, Costa Rica

Longhorned Borer Beetle

Hi Alex,
WE are not certain which of the Longhorned Borer Beetles in the subfamily Prioninae you have submitted.  It may be Callipogon barbatus, though a dorsal view photograph of the entire specimen might be necessary to be certain of the identification.

Thanx Daniel
For taking the time to try and help me ID this beetle. You’ve at least put me on the right track.
I found two more photos which may help you be more certain of your ID.
I see many similarities between the Callipogon barbatus that you suggested but also many differences.
Thank you again

Root Borer from Costa Rica

Hi again Alex,
Thanks for sending additional photos.  This will probably help immensely in identifying this Root Borer, though we need to go to the market to buy dinner before we do any additional research.

Root Borer from Costa Rica

Hi Daniel and Alex:
These are lovely shots of what I believe is a Mallodon spinibarbis (Prioninae:  Mallodontini). It could also be M. molarius, but I think that is less likely. It ranges from Mexico to South America as far down as Argentina. You could also check out the Worldwide Cerambycoidea Photo Gallery, which has several images of this species, as well as several other Mallodon species that occur in Costa Rica.  I will be visiting the Osa Peninsula next week so this helps to get me pumped (as if I needed it). Thanks.

Thanks Karl,
You appear to have nailed it again.

Thank you both.

Heres a link to a few photos I took while there.
Have fun. I wish I was headed back!

Dear T. King,
We believe you have found a Poinciana Longicorn,
Agrianome spinicollis, which we identified on Graeme’s Insects of Townsville, Australia website.  This past December, we provided a lengthy answer to someone who submitted another photo of a Poinciana Longicorn and you may read that in our archives.

Thank you so much for the reply. That’s definately our new friend!
I will pass on the information to the preschool teachers.
I note that it is a species usually not found in Alice Springs Northern Territory. Maybe a traveller? We have had unseasonally large amounts of rain and a high level of humidity over the last year. A factor?
I wonder if there have been any more sightings in Alice Springs?
Maybe the preschool could post a photo and letter in our local paper to see if they get a response?
If they aren’t interested, I am! I am sure they will be though.
I wonder what we shall do with him? Any suggestions? Food is an issue as well.
What a wonderful example of the sharing of knowledge and the potential for positive exchange and connection using the internet. Insects and other smaller species of animals are often neglected and misunderstood so thank you for giving me the opportunity to share this learning experience with these children, another smaller wonderful species!
Kind regards and much appreciation

Hi again Tarnya,
Weather, especially rain, is often a major contributing factor to insect appearances.  Additional sightings in Alice Springs are most easily researched on your end.  We would urge you to release your catch.

Longhorn Cactus Fly

Dear Melanie on the Irish Chain,
Was there any red wine consumed at your meal?  This appears to be a Longhorn Cactus Fly,
Odontoloxozus longicornis, and our very first posting of this species in 2007 included a comment from Michael W. that “Interesting that the adults like red wine.”  Flies have mouths adapted to slurping up fluids, and you were very astute to notice its feeding habits.  The Longhorn Cactus Fly is also represented on BugGuide and on the Natural History of Orange County site.

Fascinating! No red wine, but a couple of glasses of Pinot Grigio were in very close proximity to the plate.

Hi Irma,
Nearly two years ago we posted several photos of this Longhorned Borer Beetle or Longicorn in the family Cerambycidae, and we had it identified as

WOW!  That was fast!  Thank you very much.

Dear ??,
While we have been successful in quickly identifying your gorgeous Longicorn Beetle, we are unfortunately unable to assist with your own identity.  We found your Longicorn’s identity on a website of vintage Shell Picture Cards of Beetles.  It is identified as the White Spotted Beetle,
Penthea saundersi, on Shell Picture Card 318.  The Shell Picture Card website indicates:  “Card data: ‘This large and truly magnificent black beetle, with its ornamentation of whitish spots, is a native of Western Australia. It is a Longicorn belonging to the Cerambycidae family.  Calodema Supplementary Paper No. 46 (2007)  Adult beetles of this species are usually found crawling about on twigs or small branches of trees in the daytime. The larvae, or grubs, are borers. ‘  Comments: Nothing appears to have been written on the biology of this species since publication of the Shell Picture Card series.”  We also located a photo on FlickR.  Again, this is a spectacular Longicorn and we are pleased to be able to post it as there are so few photos of this species available online.

Thanks to a comment from Mark H, we now know that this lovely Longicorn is
Rhytiphora saundersi.  The Worldwide Cerambycidae Photo Gallery has a photo and Lochman Transparencies has many lovely images of living specimens.

Barb Crites

Hi again Barb,
We will continue to research and hopefully find the host tree or trees.  All indications are that this is a native species for you.  It is possible that fallen trees due to the hurricanes have provided a food source for the larvae, but most Longicorns remain in the larval stage for several years, so these two sightings are probably premature to be connected to the recent hurricanes.

Hi Daniel, I can add that this beetle looks very similar to the mango tree borer, which I would guess got here the same way the wild growing mango trees did.a local resident thinks they are a pest to our turpentine trees. How true that is I don’t know. I have a tendance to agree with you that we are seeing them now because of all the down tree matter from the hurricanes.

I live in the US Virgin Islands. After coming home today, I noticed a large (about 9 cm long) brownish-black beetle hiding in a notch in the outside of our balcony railing. I was hoping I could get a better photo if it came out from its hiding spot after dark, but it hasn’t moved yet.

This is NOT a Stag Beetle.  It is a Prionid or Stump Borer in the tribe Mallodonini.  I greatly resembles the Hardwood Stump Borer,
Mallodon dasystomus, a North American species that is known to range as far south as Columbia.  It might be the same species as this Prionid from Puerto Rico.  The site Insectoid has a checklist of species from the Caribbean.  According to the Worldwide Cerambycidae Photo Gallery, Hovorodon bituberculatum  is found on St Thomas.  The mandibles on your individual indicate it is a male.  We would advise that you steer clear of those mandibles as they look like they might do some damage.

Hi, Daniel.
Thank you for all the information. He’s still in his spot on our railing, and looking more and more like the male Hovorodon bituberculatum. I agree that his mandibles look strong and sharp and I will definitely stay out of their way.

Kiawe Round Headed Borer

Dear v.,
We thought your beetle bore an uncanny resemblance to the Mesquite Borer, Placosternus difficilis, a species BugGuide reports from Texas and the “Southern tier of U.S. states, south to Honduras; Cuba, Bahamas.
”  We then did a web search to see if the Mesquite Borer was introduced to Hawaii, and we were immediately led to another BugGuide page of an insect found in Hawaii and placed in the same genus, but with the disclaimer:  “Placosternus crinicornis (Chevrolat)  has been recorded from Hawaii but not P. difficilis.”  We followed that thread and were led to the Insects of Hawaii page on Placosternus crinicornis, the Kiawe or Prosopis Round Headed Borer which is listed as non-native.  It may also be found on an Invasive Species website.  According to Wikipedia, Kiawe or Prosopis limensis is a species of mesquite native to South America.  Since neither the insect nor its host are native to Hawaii, it is fair to say that neither are beneficial to helping to maintain the indigenous biodiversity of Kauai.

Letter 34 – Borer Beetle: Neoclytus mucronatus


Walking cricket wasp????
We found this bug in the Dallas, TX area on July 20, 2007 in the evening just before dusk. It was in the bed of our pickup so it must be able to fly. We tried finding pictures and using the guided identification links on the web, but can’t find anything. We left it in a bottle overnight and were surprised to find it fine in the morning. It has a hard exoskeleton, the markings of a wasp, and the legs of a cricket. The black covering on the back appears to be a set of wings, but we couldn’t tell. It did not act aggressive or defensive. We let it go after we took the pictures, and it crawled away with the same movements of a walking cricket. So what do you think? By the way, we love your web site and use it for scouts and for my 7 year old son, who claims to have a goal of moving to Costa Rica and becoming an entomologist. Thanks,

Hi Eddie,
This is a wasp mimic Borer Beetle in either the genus Clytus or Neoclytus. We are inclined to favor Clytus, but we will seek additional assistance from Eric Eaton to try to get a proper identification. Here is Eric’s response: “Daniel: The beetle is a Neoclytus, probably N. mucronatus, as those spines on the tip of the hind tibia are, I think, peculiar to that species. I have seen them swarming over branches broken off trees by storms. Great job just getting the beetle down to two genera! Eric”.

Letter 36 – Wood Boring Beetle Grub and subsequent Controversy


I have never seen anything like this befor here in Michigan.

Hi Evan,
Please give us some context. Did you find it in the bathroom? We don’t think so. Did you find it in the pantry? We don’t think so. Was it crawling across the driveway? We don’t think so. Was it eating the leaves on your rose bush? We don’t think so. We believe it was found in a wood pile. This is the Grub of a Beetle in the Family Cerambycidae, the Long Horned Borers. They spend their lives feeding on wood, pupate inside the stump and emerge as winged adults.

Dear Bugman I found this bug (Wood Boring Beetle Grub) in the yard and it’s all sand I was working in Rosscommon on a house in the woods but about 1 acre of it is all sand where i found it .no grass and no wood pile and no wood in the imediate area, but was close to the driveway. Thank you again for your help.

Hi again Evan,
We have a new theory. Perhaps the grub was living in cut lumber. There are species that can emerge as winged adults years after construction.

We stand chastised
(09/30/2005) Hi. My friends and I read your site daily to look at all the fastinating new bugs. We were quite dismayed with your reply to Evans Owens who sent you a picture of the wood boring beetle grub. Were you courteous? WE DONT THINK SO. Were you pleasant? WE DONT THINK SO. Were you nice? WE DONT THINK SO. Were you polite? WE DONT THINK SO. We think that since you are in the “public eye”, that you should not chastise the people who write to you for help. What good really would it have done if he told you where he found it? On July 17th, this year, Dave and Wendy told you they found a pseudoscorpion in a box of cereal. Did that help you identify it? WE DONT THINK SO !!!

Hi there, This wasn’t meant as a discourtesy as much as it was meant to comment on the lack of information in the query. We stand chastised and will post your comment beneath our original response. At least we didn’t use email shouts in our response which was actually meant to be funny. Occasionally a joke will fall flat. We hope our unintentional rudeness hasn’t cost us a reader. We still love the letter with the Pseudoscorpion in the cereal, and in actuality, we did identify it.

Sorry everyone took it as rude, I took it as funny, As in, where did you find it? I did not feal insulted or put down in any way. I guss I should of put LOL after I found it by the driveway , (LOL) But I also appreciate the concern of your readers, And I thank them too. The home is over 10 years old and it’s a modular home, And the wood is all treated lumber that we where using, so how it got there is beyond me, and your guess is probably better than mine (LOL) and there is about 100 acres of woods there . P.S. im not in to bugs much, but i do like to know what it is im looking at when i do see one I’ve never seen before and im glad I found your website, I now have it saved in my Fav. websites. and I thank you for your help.

Additonal Information
(09/30/2005) Evan Owens Ash Borer
Hello Bugman,
I’ve been appreciating your site for some time, since ID’ing a Great Golden Digger Wasp flying around hoarding Katydids in my wife’s flowers, and regularly click on it to see what’s up on your main page. Thanks for the work you’re doing. I’m just writing to shed a little light on a picture on your main page. I’m from northern lower Michigan and the boring worm that Evan Owens on 9/29/05 has pictured is an import that is giving the forest service around here fits. Since it is a newcomer to Evan, it is likely an Emerald Ash Borer grub, and it kills trees, specifically Ashes. Southeastern Michigan has had its parks and woods practically culled (an estimated 8 to 10 million trees since their introduction in 2002) of Ash trees over the past few years, and the insects are continually spreading as people move firewood (containing the voracious larva) to northern and western campsites in our state, Ohio, and Indiana. If Evan, or anyone else that spots them, is outside the known range of these pests, Michigan has a hotline for reporting their spread and disposal sites for infected wood (866-325-0023.) Michigan also quarantines areas and bans the transporting of firewood but the rules are all but unforcible. The best tool right now for stopping them is early detection and eradication, but that will only come with education. For further information, here are some very informative links that include pictures of the insect, where it came from, and efforts to contain it:
I know your site isn’t dedicated to removing pests, but this is one exotic that could use the boot.

Thank you for your insiteful letter Weston. One comment we would like to add is that many Wood Boring Beetles have similar appearing grubs and this might actually be a native species. We also stand by this being a Cerambycid and not a Buprestid which the Emerald Ash Borer is. Cerambycid grubs have much larger heads.

Letter 37 – Gorgeous Longicorn from the Philippines: Cereopsius praetorius possibly


Some Ladybug Impostor
February 25, 2010
Ever since I bought my camera, it had always been my wish to be able to take a photo of a nice red ladybug with those cute black spots. I never had a chance, however, as I always see those ladybugs with a dull yellow color instead. One day, during a company outing, I saw this HUGE ladybug-like insect on the lamp post and I thought my dream of a ladybug picture had finally come true (with a large one to boot!). But looking at it, it doesn’t really seem to be a ladybug at all, except for the colors. This was confirmed by everything-ladybug.com, who said that ladybugs are fairly consistent in their oval/round shape, which is not true in this insect. So, since my dreams are all crushed now, I just want to know what bug this is who tried to fool me into thinking that it’s a ladybug… Thanks in advance for your help in this!

Longicorn from the Philippines

Dear Beverley,
While we think Ladybugs are lovely creatures, we feel that the subject of your photo, a Longicorn in the family Cerambycidae, is far more special.  We tried doing a web search, and found the Insect Designs website of specimens for sale.  One species from the Philippines,  Cereopsius praetorius
, looks close, and there is a note that the pattern varies.  We found a second website, Saluguband Philippine Beetles, with images of dead specimens as well.  Though the markings on the dead specimens are similar to your photo, the colors are not nearly as vivid.  Often dead specimens lose their vibrant coloration.  Perhaps Karl will have better luck confirming this identification.

Hi Daniel,
Wow, I’m really impressed how fast you guys can identify bugs.  Anyway, I’m also grateful for your reply.  Now I can appreciate this ladybug impostor more knowing that it is far more special than the ladybug it is trying to look like 🙂

Karl Agrees
I think you got it, Daniel. It must be a Cereopsius and although there are at least 10 species in the Philippines, none look nearly as close as C. praetorius (I was able to find images of all but one). K

Hoping you can help with identification of this longicorn. I looked through all the sub-families and tribes under “Cerambycidae” on Bug Guide and did not find this one… rather frustrating, but a good use of time, nonetheless.
Many thanks,

Dear Critterphile,
We were expecting this to take quite a chunk of time, but we got lucky quickly.  We have correctly identified your Longicorn as a Banded Hickory Borer,
Knulliana cincta, thanks to this and other Bugguide images.  This BugGuide posting highlights many of the distinctive features:  “spines on thorax, apex (tip) of elytra, and legs (femora). These are mentioned as distinguishing features in field guides.”  BugGuide also notes:  “There are no other NE longhorns of similar size and coloration that have strong spines on the femora, pronotum, and elytral apices.” 

Letter 39 – Neoclytus Borer Beetle from Oregon


What’s this bug
Can you tell me what species of Neoclytus this is? I live in Medford, Oregon, and this is the second specimen I’ve found in a week (February) on stacked firewood. We live primarily among Ponderosa pine and Douglas-fir, but there is also a lot of Madrone and White and Black oak here as well. Hopefully it is a native species, and I won’t have to worry about my woods. I’ve kept one alive on a bread and peanut butter diet for two weeks now. Thank you,
Jerry Burke

Hi Jerry,
We need to do additional research, including requesting assistance from Eric Eaton, before we can get you the exact species of Neoclytus you have found. Here is Eric’s opinion: ” The Neoclytus is probably N. conjunctus, but there is a great deal of individual variation in the markings. Eric “

Letter 40 – Prionid from Australia may be Acacia Longicorn


Subject: australian beetle or bug
Location: Maryborough, Queensland, Australia
November 18, 2014 4:03 am
Dear Bugman
I don’t even know if this site is still running or tended regularly, so I will just send this and hope for the best.
I live in Australia, the land of Poisonous Things. I am wary of anything that looks like it might bite me, and this insect has me horrified.
It can fly. It reminds me of a weevil, but bigger – almost as long as an adults thumb. Hard, dark brown, shiny shell with thick legs and antenna. Long body.
And the most awful looking pincer type arrangement at the head.
It looked awful and I had my husband remove it from the house. I have never seen anything quite like it – can you help?
I have attached the clearest picture I could take without getting too close!

Possibly Acacia Longicorn
Possibly Acacia Longicorn

Dear Carly,
This is a Longhorned Borer or Longicorn in the subfamily Prioninae, and we believe, based on images posted to BushCraftOz that it might be an Acacia Longicorn,
Eurynassa australis.  According to BushCraftOz :  “Found under eucalypt bark, with head protruding. Larvae live in dead wood of acacia species. Large beetle ~40 mm.”  Beetles in the family Cerambycidae have powerful mandibles, and large individuals, like the one you found, might deliver a painful bite if carelessly handled, and the bite might even draw blood.  Though a nip might be painful, it is not dangerous as the Longicorns are not venomous.

Hi Daniel
Thank you for the information. I just couldn’t find any details on a native species with such big pincers!
I really appreciate your email, and the time to look into it for me.

Hi Kayla,
This is a Longhorned Borer Beetle in the family Cerambycidae, and we are very confident that it is a Spotted Tree Borer,
Synaphaeta guexi, based on images posted to the Natural History of Orange County site.  It does fly and it has very strong mandibles it uses to chew its way to the surface after it matures from a wood boring larva to a winged adult.

Attached is a picture of a larvae caught near our cabin in Arnold Ca (Calaveras County). Can you help me identify what pest this is? We have lost one pine tree to it and may lose others given the drought conditions. Thanks.
Larry Rillera

Hi Larry,
This is some species of Long Horned Borer Beetle in the family Cerambycidae. Probably nothing short of disection and DNA analysis will get you an exact species. If your goal is an exact species, you will need to research which members of the family feed on pine in your locality and try to narrow the possibilities from there. BugGuide is a great source for information. Beetle larvae in general are much more difficult to identify than caterpillars. We will see if Eric Eaton can provide a novice’s guide to differentiating Cerambycids from Buprestids, the two main wood boring families of beetles.

Update: (06/14/2008)
Ok, how to tell whether it is a longhorn beetle grub (Cerambycidae) or a metallic woodborer larva (family Buprestidae). Well, in the larval stage, cerambycids are known as “roundheaded borers” while buprestids are called “flatheaded borers.” Indeed, it would appear as though the front quarter of a buprestid larva has been flattened like a pancake, greatly expanded on either side, followed behind by a much more slender body. Roundheaded borers are not flattened, though may show some depressed areas on the thorax, as the specimen in this image shows. Buprestid larvae, as they bore, leave behind them fine, tightly-packed “frass,” often in a ringed or fingerprint pattern. “Frass” is a polite name for insect poop, and it amounts to sawdust for woodborers. Roundheaded borers leave behind very coarse, fibrous frass. Apparently, a foolproof way to differentiate the two is thus: buprestid larvae have a hardened plate on the first segment behind the head, both on top and underneath. Cerambycid larvae lack the plate on the underside (per Western Forest Insects by R.L. Furniss and V.M. Carolin, 1977, U.S. Department of Agriculture Miscellaneous Publication No. 1339). Hope that clarifies things (seems like one has to put everything under a scope to tell the difference….). Take it easy. Great work as always on everything else.

The second picture is actually our snack this afternoon, just to share with you.
Signature: Joseph


Hi Joseph,
Your beetle is a Long Horned Borer Beetle in the family Cerambycidae.  They are frequently called Longicorns.  We are trying to tear ourselves away from the computer to enjoy the morning sunshine since we have had a string of storms here in Los Angeles the past few days, so we are not going to take the time at the moment to hunt down a species identification for you.  Perhaps one of our readers will provide a comment.  Your snack appears to be Crickets with Green Onions, but we are not certain.  Can you verify the identity of your snack as well as providing any information on where you purchased it?  We understand insect food items are commonly sold by street vendors in Thailand.

Hi Daniel,
Thanks for your quick reply.
The snack is not cricket with green onions. I really have no idea the English name but in Thailand it is know as “maeng-ser-din” it is not even a Thai language but rather a dialect spoken by the north-east people of Thailand which constitute the largest group of ethnic people in Thailand. They are known as the Essan or Isaan people. If you follow the news here they belong to the red shirt people. I could not find a live maeng-ser-din so I Googled and found this:
These are not like from the drain or some dirty places on the contrary they are reared in a form like his:
As for the green stuff it is commonly known as Pandan leaf here. South East Asian cooking uses a lot of this to add a natural sweet fragrance or natural green colour to the food. It is also use to wrap food and deserts to add fragrance. The other name is Screw Pine leaf or Pandanus and looks like this:

Crickets: Photo from the Internet

Thanks for the follow up Joe.  We wish you had included links to the images you found.  We had no luck googling “maeng-ser-din” and we wanted to allow our readership to see the images you attached to your response.  We don’t normally use images grabbed from the internet, but in this case, we are making an exception.  The image you attached does depict Crickets, and Crickets are easy to raise in bulk in captivity.

Hi Daniel and Joseph:
The Longicorn appears to be a female Gerania bosci (Lamiinae:  Lamiini), which occurs from India to Indonesia. There is some variability in the coloration, ranging from brown to black markings on a nearly white to bright yellow background. The males are larger and have much elongated appendages. Regards.

Your name is remarkably similar to the name of your Longhorned Borer Beetles, commonly called the Kiawe Borer.  It is a non-native species that feeds on introduced, cultivated mesquite plant.  Since Gliricidia and Mesquite are in the same family, perhaps the Kiawe Borer has adapted to boring in the wood of the former.

Letter 47 – Longhorned Borer from Ecuador resembles relative from Arizona


Subject: Interesting Orange and Black Beetle Found in Ecuaodor and Arizona?
Location: San Clemente Ecuador and also one in Yuma Arizona
March 28, 2013 3:34 pm
Dear Bugman,
I recently sent in a picture of an interesting beetle. In my excitement and haste I didn’t get permission from the photographer. After re-reading the submission page I did send an email to the photographer and got their permission to use the photo to try to identify this odd beetle. I will include the information they have provided about the beetle, and send the information on to them as well because they are very curious about the insect.
My original submission: About 14 years ago I came across this odd beetle. It was Summer time in Yuma Arizona, and we were eating watermelon when this bug flew onto my plate. It was about an inch and a half long. Being 10 it freaked me out and I never did get a picture of it. I never forgot about it though. I tried very hard to identify the bug but never did find out what it was. Today I Googled ”Black and Orange Antennae” and finally found a picture of the bug I saw. So maybe now I can finally put a name to this bug with your help! 🙂
More information on the insect provided by John and Mary from their blog: The bug was found in San Clemente Ecuador. Counting the antennae the beetle was about one and one half inches long. When it was flying around it looked like a large wasp. I tried to get a close up of the head to see the eyes, but it is unclear where the eyes are. There also appears to be some hair-like growth on the face!
Any ideas? Thanks so much for your time and effort.

Hi Nichole,
We really doubt that the beetle you saw in Arizona is the same species as the beetle in the photo from Ecuador, but they might be in the same family.  First, thanks for getting permission from John to reproduce his photo.  John’s beetle is a Longhorned Borer Beetle or Longicorn in the family Cerambycidae, and we might be able to identify it to the species level.  There is a better database online for North American species, and while it is impossible to state with any certainty that we can identify the beetle you saw 14 years ago without photo documentation.  A similar looking beetle that is found in Arizona is
Aethecerinus latecinctus which we found on BugGuide.  We will write back if and when we identify the Ecuadorean Longicorn.

Hi Daniel and Nichole:
My initial thought was that the Ecuadorian Cerambycid was probably in the genus Trachyderes, many of which look quite similar. Several Trachyderes species are native to Ecuador but none of them are quite right, particularly with regard to the color patterns of the antennae. I believe John’s is probably Andrachides transandinus (Cerambycinae: Trachyderini). The genus appears to have only the one species and it is endemic to Ecuador and Peru. Its similarity to Trachyderes is evident in that its original name was Trachyderes transandinus. As for the beetle from Arizona, I suggest checking out the closely related and similar T. mandibularis which is well represented on bugguide.net.  Regards.  Karl

Dear Zarek,
We do not receive many submissions from Africa, except for South Africa, so we are thrilled with your photos.  Additionally, identification of African species can be especially challenging because the internet does not contain as many insect sites devoted to African species as it does sites devoted to North American, Australian or even Costa Rican species.  Thanks so much for doing the research and identifying your Longicorn as
Tithoes confinis, though we still want to support that ID with a link.

Ed. Note: We found this link to the ColeopTerra website that confirms the ID of Tithoes confinis.

Letter 49 – Giant Longhorn from Bolivia


Can you identify this big?
I came across this bug while on a mission trip to Bolivia, I cannot for the life of me remember what they called it. Can you please Identify it? I have attached it to this email

Hi Lauren,
This is a Giant Longhorn Beetle, Macrodontia cervicornis. We found information on Wikipedia that states: “Macrodontia cervicornis is the largest and best-known member of this genus of long-horned beetles, and this species is sometimes considered the second longest among all beetles, with known specimens exceeding 17 cm in length. A fair bit of this length, however, is due to the enormous jaws, from which it derives both of the names in its binomen; Macrodontia means ‘large tooth’, and cervicornis means ‘deer antler’. For that reason, it is generally excluded from consideration by purists who do not take the jaws, legs , or antennae of a beetle into account when determining length. This species is known from the rain forests of Colombia ,Peru ,Bolivia , the Guianas, and Brazil , but there are an additional seven described species in the genus, extending the overall range of the genus from Guatemala to Argentina .”

Update: (07/24/2007) Macrodontia [the grubs] are a delicacy
Hi Daniel,
Impressive images of that beetle. There’s evidence that these guys were once meals in the Amazonian rain forest; a desirable serving not only of protein and vitamins but of pleasing and energy-giving fats. While that still might be true, I have a feeling that these days someone finding a grub in the jungle would be likelier to raise it to adulthood and sell it as a specimen than eat it. Which is kind of sad, really. Best,

Your observation that your beetle resembles a Locust Borer is a good one as they are in the same family of Long Horned Borers, Cerambycidae. We do not recognize your particular beetle, and a quick search of BugGuide did not produce an answer for us.

I took this photo of an insect sunning itself on the side of my house. I searched your files and online.
the closest I could narrow the ID was to the BANDED ASH BORER beetle, but all the photos I found lacked yellow stripes across the thorax. Otherwise, it seems to be a close match.
is this a banded ash borer, or perhaps a relative?
We have been losing trees in the Chicagoland (IL) area at an alarming pace. (mostly elms and ash), and work crews were in my neighborhood felling diseased trees last week.
My guess is this bug is in the process or relocating to new food source.

Neoclytus scutellaris
Neoclytus scutellaris

Dear Jill,
You are quite astute to observe the similarities between your insect and the Banded Ash Borer,
Neoclytus caprea, since they are in the same genus.  According to BugGuide, there are 25 members in the genus Neoclytus in North America, and many look quite similar, probably requiring the actual examination of the specimen by an expert in the family Cerambycidae to determine the actual identity.  Based on the striping pattern on the thorax and head, we believe your individual is Neoclytus scutellaris, based on its similarity to this individual posted to BugGuide.  The species has no common name, and according to BugGuide:  “Larvae feed in sapwood of (dead?) oaks, hickories, also grape.”  It is also worth noting that adults do not feed on wood, and they are most commonly found taking nectar from flowers, sap, fruit and other sweet substances.

Thank you for your response and reassurance! (I’m so glad this bug didn’t go on to feast on my elm tree). We have lots of native berry trees in our yard, and the bug was near our cherry tree when the photo was taken. Your description of it’s feeding habits makes sense.
Thanks, Jill

Eric’s / Jenny Harrison’s large ‘bycid carries the name Tithoes confinis (Laporte de Castelnau, 1840). It is likely a female, and not as large and fearsome as individuals of this species often are. The species is widespread through most of the continental Afrotropics and in the right habitat they are bound to come to light on a good light-trapping night; they come in around 1-3 hours after sunset. Its pedigree is Cerambycidae: Prioninae: Acanthophorini.

Hi – We love your site, and have gotten lots of good information and identifications from it before. Thank you so much. I’m sending this again, because my embedded photo didn’t show up in my email for some reason. Thanks! Here’s the current question – we live in east of the San Francisco Bay area of California (but not as far east as the Central Valley). At a wildflower garden that I maintain at a school site, we’ve noticed bees congregating on the poppy seed heads about sundown. By dusk, there are several bees per stem, all faced head-down. They are non-aggressive – just seem to jockey for position. I think they are some sort of mason bee, but this behavior has me puzzled….any ideas?

Dear friends, The photo of the beetle sent in by Richard of Kiama looks remarkably like a picture in a book I have of a Banksia Longicorn: Paroplites australis (family Cerambycidae). The text says they are “slender reddish-brown beetles about 5 cm long with antennae of similar length. The larvae are large, fleshy, yellowish legless grubs, broades at the head end. ” The larvae bore tunnels in Banskia trees and pack it with the debris from their chewing. Regards,

Bachelor Party of Longhorned Bees
Bachelor Party of Sweat Bees

Dear Curious,
This is a Bachelor Party of male Longhorned Bees in the tribe Eucerni, but we are not certain of the species.  Male Bees do not sting, so they pose no threat to you.  You can see similar images of Bachelor Parties from North America in our archives.

Update:  February 5, 2014
We got a comment that these might be male Green and Gold Nomia Bees,
Lipotriches australica, a type of Sweat Bee that also exhibits this Bachelor Party behavior in Australia.

Letter 65 – Bachelor Party of Long Horned Bees


More clumps of mining bees
Hello folks!
Enjoy the website and it’s addicitive to say the least! Discovered these little critters clinging to our lavender, here in Eagle Rock, a northern suburb of Los Angeles right next to Pasadena. Someone else was asking why these — apparently mining bees, from what you told the other photographer from July 29, 2007– male bees were doing this. All I know, is that for that last month or so, (that would be mid-May to mid-June) these fellows flitter about the lavender during the day and then, when it cools down, they all gather back to this SAME STALK and huddle together for the night. Sometimes, the stalk is completely covered with them! They are there in the mornings when I go get the newspaper! Not sure what the behavior means, but I am glad to see them everyday! Best,
Brenda Rees
Eagle Rock CA

Hi Brenda,
We actually believe these are Long Horned Bees in the tribe Eucerini. There is a photo from Arizona posted to BugGuide, and the photographer says 100s of bees congregated on dried weeds at sunset. We have gotten reports of this nightime aggregating behavior in solitary Hymenopterans, both bees and wasps. We have seen them called Bachelor Parties since they are only males. We will contact Eric Eaton for verification that these are Long Horned Bees and see if he can provide a genus. Meanwhile, perhaps we will meet at Eagle Rock Italian Bakery some day. We love the semolina bread they only bake on Friday. We can also be spotted at the Blue Hen and the Coffee Table on occasion since we live nearby in Mt Washington. Thanks for the nice letter and wonderful image neighbor.

Letter 66 – Misidentified Longicorn




Balsam Fir Sawyer
Location:  St. Louis County near Cromwell, Minnesota
August 19, 2010 8:44 pm
Hello! I’ve found what I believe to be a Balsam Fir Sawyer on our wooded land in St. Louis County in northern Minnesota. I haven’t been able to find much information about this insect and wonder if you could tell me bout it.
Thank you very much for any help you can provide.
Lynne Schoenborn


Hi Lynne,
We looked up the Balsam Fir Sawyer,
Monochamus marmorator, on BugGuide and we found this cited information: Larvae of the balsam fir sawyer, Monochamus marmorator Kby. (Coleoptera, Cerambycidae), contain midgut digestive enzymes active against hemicellulose and cellulose. Cellulases from larvae fed on balsam fir wood infected with the fungus, Trichoderma harzianum Rifai (Deuteromycetes, Moniliales, Moniliaceae), were found to be identical to those of the cellulase complex produced by this fungus when compared using chromatography, electrophoresis, and isofocusing. When larvae are maintained on a fungusfree diet, their midgut fluids lack cellulolytic activity, and they are unable to digest cellulose. Cellulolytic capacity can be restored by feeding the larvae wood permeated by fungi. We conclude that the enzymes which enable M. marmorator larvae to digest cellulose are not produced by the larvae. Instead, the larvae acquire the capacity to digest cellulose by ingesting active fungal cellulases while feeding in fungus-infected wood.”  reference: http://www.osti.gov/energycitations/product.biblio.jsp?osti_id=7058239 We would love to know why it is on Invasive.org because there is no information regarding its native region.  Maybe mardikavana knows something about the Balsam Fir Sawyer.

More Questions
August 26, 2010
Thank you very much for the information.  Does this quoted article mean that the larvae only feed on decaying wood infected with fungus?  Are eggs laid in healthy trees or only dead and decaying wood?  Will they damage healthy trees?

Hi Lynne,
Sadly we are unable to answer your questions as we are not scientists.  We have found what information we were able to uncover on the internet.  We would suggest that you provide a comment on our posting of your letter so you will be notified in the future if any experts can supply additional information.

Update:  September 16, 2021
After identifying a Balsam Fir Sawyer, we realized this Longicorn is misidentified and we need to search for its identity.

Dear Brian,
This striking Locust Borer is an excellent Yellowjacket mimic.  According to BugGuide:  “Considered a serious pest of Black Locust; previously weakened or damaged trees are often killed by the larvae. Previously confined to the native range of Black Locust in the northeast, it has spread with the trees throughout the US and parts of Canada. Black Locust is used for reclamation and similar projects where trees are likely to be stressed and thus more vulnerable to damage.”  Adult Locust Borers are often found feeding on Goldenrod.

Dear Adam,
The location you indicated for this sighting, UTM 17T271051 5135443 did not produce any matches in our web search.  For all purposes, you did not provide us with a location that we can use to assist you.  The desperation in the tone of your letter would indicate that this is important, yet you failed to assist us.  The best we are able to do with limited information is to say this specimen somewhat resembles the Banded Ash Borer, Neoclytus caprea, which can be viewed on BugGuide.  If the species is not correct, we are guessing it is a relative in the same genus Neoclytus, or at least in the tribe Clytini.  These clues should enable you to conclusively identify this specimen based on information you have that you have not provided for us.

Letter 76 – Borer Beetle: genus Neoclytus


Apple tree lovers
I had to cut down my apple tree. It was hit with some disease from my neighbor’s fruit tree and died. When I went to cut it down, I found several of these bugs crawling up and down the trunk and on the branches. They were about a 1⁄2 inch long. At first I thought they might be some sort of immature wasp since my yard seems overrun this year with paper wasps, but after looking carefully at the photos I took, it doesn’t seem likely. I’ve asked several friends who are pretty good at bug ID but no one has seen these before and no one has a name for me. Can you help? I’d like to know if they might have helped cause the tree’s death or if are they something that might endanger other plants or people. Thanks for your help. This web site rocks!

Osmopleura chamaeropis.  According to BugGuide:  “Larvae feed on Cabbage Palmettos (Sabal palmetto) in Florida” and its range is “Florida and Georgia and recently, one specimen from Texas.”  Perhaps your North Carolina sighting is a range expansion due to global warming or the cultivation of palmettos in North Carolina, or perhaps a specimen was accidentally transported in baggage or with goods.

Letter 82 – Cactus Longhorn


Unknown beetle
Stuart from Tucson again. This time I have an unidentified beetle hanging out on an ocotillo in the back yard. Looks like it could be a species of long horn beetle but I am not sure. The speciman was approximately 1 – 1 1/4 inches from head to toe (not including the antennas or what ever you call those on a beetle).

Hi Stuart,
We have reservations saying this is a Female Prionus, though that is our best guess at the moment. Certain anatomical features seem inconsistant witht he genus. We will check with some real experts to get you an answer. Eric Eaton provided the following identification: ” Ah-ha! Well, you have the right family:-) This longhorn beetle is in the genus Moneilema, the “cactus longhorns.” They are rather large, flightless, and mostly nocturnal, venturing out at night to feed on fleshy cacti, especially Opuntia prickly-pear and cholla. As larvae they mine at the base of the cactus, or in pads that are prostrate on the ground. The adults are thought to mimic Eleodes darkling beetles, even standing on their heads at times as if prepared to spray an attacker (as Eleodes can do). Very interesting beetles, and quite common, even if not often seen. Eric “

Letter 88 – Cerambycid Borer Beetle


what is it?
These are swarming a new stack of wood beside our house. I’ve never seen them before. Do you know what it is? I forgot to mention, we live in west Michigan

Hi Michelle,
This is a Long Horned Borer Beetle possibly in the genus Clytus. BugGuide lists two species in the genus, and Clytus marginicollis seems to be the closer fit. The larvae are the wood boring stage of the insect, and the food is dead wood from hard pines. The adults fly from March to July. Perhaps the adult insects found a rich food source for the larvae and decended upon your wood pile, or possibly the pile included some wood that was already occupied by the larvae which emerged together as adults.

Hey Guys :
Not being picky here … but the cerambycid beetle on 21 April from West Michigan looks closer to Neoclytus caprea, than anything else. A slightly beter photo would seal it. N. caprea emerges in early Spring and is found most commonly depositing its eggs on logs of ash trees, although they will utilize oak, and elm. The individual in the photograph appears to in fact be a female, and she looks like she might just be trying to lay some eggs on that cut wood. Cool !

Alder bug
Can you tell me what this is? It came out of some furniture my boss bought out in Oregon last fall. We just found 3 holes with sawdust, and one beetle hanging out on the arm of the chair.

Hi Mark,
We are guessing the subject line “Alder Bug” refers to the type of wood on the furniture. The antennae on your insect look like those of the Banded Alder Borer, Rosalia funebris, but the coloration seems slightly off. It is difficult to be certain because of your camera angle. It is also possible that a newly metamorphosed insect might have coloration not consistant with older specimens. We will ask Eric Eaton for his opinion. Here is Eric’s speedy response: ” I believe the insect in question is possibly Synaphaeta guexi, the Spotted Tree Borer, found from BC to California, curiously recorded from oak, poplar, maple, and willow, but apparently not alder:-) I suspect it is a generalist and probably attacks alder as well. I’m not certain, but that is my best guess. Neat insect.” Several days later Eric wrote back: ” Oh, I just mentioned that Art Evans had confirmed my species ID of the longhorned beetle from the Pacific Northwest. It’s all good. Eric “

Dear Carolyn,
Your image is indeed quite blurry, which makes us sad because we believe we have correctly identified your female Dimorphic Flower Longhorn,
Anastrangalia laetifica, on BugGuide, and it represents a new species on our site.  Even though your image is blurry, the distinctive markings leave little doubt as to its identity.  The term Dimorphic in the name refers to the obvious visual differences between the sexes, which makes them appear to be different species.  Females are colored similarly to your individual, while males are black or brown.

Thank you very much! I tried finding it myself using the BugGuide, but could not even get there from Insecta.  Is there a way to browse the categories that would more easily lead me to the right page.  I completely agree that this BugGuide pictures of this species clearly identify my bug.  I could not find information anywhere on what they eat – apparently plants, but nectar?  Petals, leaves?  Do you know?  (My search, however, led me to much fascinating information, for example, about butterfly color production by forming gyroids.)
Thank you again, and thanks in advance if you find any info about their feeding.
Carolyn Spier

Hi Carolyn,
We have no advice on how to best browse BugGuide as one needs a basic understanding of insect orders before being able to search successfully.  The same is true of our site, however, our search engine works quite well if you type in descriptive words, however, as we stated earlier, since this is a new species for our site, you would never have found your species identification on our site.  We think of Flower Longhorns as being nectar feeders, however, BugGuide has this to say on the family Cerambycidae information page:  “Many adults (esp. the brightly colored ones) feed on flowers.  Adult feeding requirements are variable, with some species taking nourishment from sap, leaves, blossoms, fruit, bark, and fungi, often not associated with larval hosts; others take little or no nourishment beyond water.”

Thank you so much for taking the time to answer me, twice!  I prefer to believe that this brightly colored female is the nectar sucking type – until proven otherwise.  I wonder what the larvae eat, though.

Hi again Carolyn,
The original BugGuide link we provided for you was to a photo and it does include food information.  According to BugGuide Larvae are borers in “Pinaceae” which is the family that includes pine as well as cedar, fir, hemlock, larch and spruce, though the Dimorphic Flower Longhorn might only use one genus as the host.  This information is provided under life cycle:  “According to Dennis Haines (pers. communication, HW) floral hosts of adults include Calochortus (Liliaceae); Ceanothus (Rhamnaceae); Achillea, Heracleum (Apiadaceae); Eriodictyon (Hydrophyllaceae).” 

Hi Daniel,
I went again to that original link you sent.  Now I see the tabs for the other info.  Thanks!  It fits that I live on serpentine in pine/oak woodland.

Letter 96 – Double-Banded Bycid


Unknown Beetle
Hi Bug Guy,
Love your site! I look up everything I’m not sure of and find wonderfully interesting bugs in my searches! Thank you for this great website. Here is a beetle I came across recently on my walk in the desert in Cochise County, Oct 01 2007. I was unable to find an exact match at whatsthatbug and hope you can help me with the ID. Thanks again,

Hi Carol,
The reason you were unable to identify your Double-Banded Bycid, Sphaenothecus bivittatus, on our site is because until now, it was not represented. We matched your image to a photo on BugGuide, and that specimen was also in Arizona. We will check with Eric Eaton to ensure that our identification is correct.

We found this guy camped out on a particular rose bush for several days.  Its contrasting colors and antenna made it stand out.  We are guessing that it is a longhorn beetle just because of its incredibly long antenna.  We searched Bug Guide and thought it’s shape and antenna resembled  several different longhorns including some flat-faced (hippopsis) and flower longhorns, but we could not find a true match.

Dear Curious,
You are correct that this is a Longhorn Beetle in the family Cerambycidae, and the entomological “nickname” for members of the family is Bycid.  This is a Double Banded Bycid,
Sphaenothecus bilineatus, which we quickly identified on BugGuide.  According to BugGuide:  “Larval hosts: Mesquite (Prosopis glandulosa) and Roses (Rosa spp.).”  The Double Banded Bycid is also pictured on Texas Entomology.

Dear Séamus,
This is an unusual double crested Longicorn in the family Cerambycidae, and we eventually located it on Insetologia where it is identified as
Hypselomus cristatus.  Additional images can be found on Cerambycidae of the World.  According to Oncid ID:  “The combination of the following characters will help to distinguish this genus: large eyes; narrowly separated antennal tubercles, contiguous at base; bowed scape, gradually expanded to apex; and base of elytra with two longitudinal, arcuate, strongly elevated crests, each crest studded with several round, shiny tubercles.”

Loved this Longicorn

Hey there, I can’t find a picture of this longicorn anywhere to ID it. I fell in love with him.
Colour is drab, but cute factor is enormous (see pic 2)
Body 17mm, antennae 25mm. (one appears to be broken short)
Lived in my flat for a week. After looking up a similar bug to find what habitat he would like I realised how obvious it was – his markings and antennae shape are perfect camouflage for aussie leaf litter.
Photos are my attempt to coax him onto paper with moist woody bits . Instead he just dragged some onto himself. Ah, gotta love em.

Dear Carlos
Thankyou so much for your reply, it was incredibly helpful. When I looked at the previous request you directed me to, here in this vast Australian continent, I was amazed to see the post was from my suburb.
Lane Cove, although close to the city, extremely built up and urban, is lucky to back onto Lane Cove National park – a diverse old ecosystem. Perhaps this odd variety evolved there, the coincidence is extraordinary.

This is a female Lesser Pine Borer, Acanthocinus nodosus, which we identified thanks to an image in “Beetles of Eastern North America” by Arthur V. Evans, and we verified that identification with this BugGuide image.  According to BugGuide:  “Medium-sized longhorn beetle, gray with distinctive pattern. Long antennae in both genders, but males have a tuft of hair on the fourth segment (see photo above) and significantly longer antennae than the females. Female has pygidium modified into a tube for ovipositing.”  So, what you thought was a stinger is actually the pygidium that is used by the female to lay eggs.

Awesome!! Thanks so much!!  Now I can brag to my fellow firefighters that I knew what that was!!
Thanks again!

Letter 112 – Female Stenodontes sp. has ovipositor, not phallus


RE: phallus or stinger…but on a beetle?
Hello, I love your site.
I found this guy while I was walking in our office parking garage. A friend here at work said “beetles don’t have stingers” so, I guess it could be a phallus. It most closely resembles what you have described on your site as a California Prionus beetle, but the pics you have don’t show a stinger. What is this bug, and what is the pointy-thing?
Courtney Cavness, Austin Texas

Hi Courtney,
Yes your beetle does look like one of the Prionus, but beetles do not have stingers, and the appendage is not a phallus either. We suspect it is an ovipositor since this type of beetle lays eggs in trees, but we will turn to an expert, Eric. Below is his response:

Dear Daniel:
Had to laugh at this one:-) This is indeed another prionid longhorned beetle, but it is a Stenodontes sp. (or what used to be called Stenodontes anyway, I think they changed the name).
The funny part is that this is a FEMALE! The “stinger-phallus” is actually her ovipositor, what she lays eggs with in the crevices of bark. When beetles die, females often evert the normally retracted ovipositor. Who knows why?
Male Stenodontes resemble a prionid crossed with a stag beetle, as they have enlarged jaws (and can USE them, let me tell ya!). Looking forward to seeing the site back up in October. Oh, BUGGUIDE.NET had THEIR server crash, so they are temporarily out of commission also. Bad month! It should be running again by October, but you might want to check, and put a notice up to that effect if it is still not up when your site goes back online.
Take care.

Hi Amy,
This is some species of Flower Longhorn in the subfamily Lepturniae. We could not find an exact match on BugGuide. We will see if Eric Eaton recognizes the species. Here is what Eric has to say: “Gee, I can’t find an exact match in Yanega’s guide, either, but it looks like it might be a species in the genus Trigonarthris. Lepturines are notorious for extreme individual variation, so that doesn’t help. There is a great site, though, someting like cerambycidae.com or cerambycid.com, that has some great images. You might try that, too. Sorry I can’t be more definitive. Eric”

Need help identifying this borer beetle
I found this nice beetle flying low around the base of one of the trees in my backyard yesterday. (I have no idea what kind of tree it is, sadly.) I thought it was a wasp at first, by its flight pattern. It is almost exactly 1 inch long, not including antennae, which are about half an inch. I noticed after I took it inside to take its picture that it makes an quite audible shrieking sound when I pick it up.
After looking through all 13 beetle pages on your site and not finding a match to my beetle, I decided to send it in. 🙂 At least during my searches, I determined that it was some sort of borer. I’d like to get an exact match so I can eventually include the beetle in my insect collection. Thanks,

No sense searching unless you have nothing else to do Eric.  Like I wrote, there were many similar ones.  The person wrote:  “They seem to love early mornings. Thats the only time i can catch them out and about.”  Since It was early morning, I did not correct the red color of the light.  Here is a color corrected version, though it is still off color.

Lori Mackay – Photographer

hi Lori,
We are confident that this is a Flower Longhorn in the subfamily Lepturinae, but we are uncertain as to the genus or species. It resembles several postings to BugGuide. It resembles the genera Typocerus, Strophiona, and Stenostrophia most closely. Perhaps Eric Eaton can be more conclusive.

Hi, Daniel:
I’m fairly confident that the image is of a species of Xestoleptura, perhaps Xestoleptura cockerelli or X. crassipes. Lepturines are really a bear, especially since the names of the genera seem to change fairly frequently….

Letter 123 – Flower Longhorn: properly identified as Lion Beetle


winged nonflying long antennaed, solitary
August 3, 2009
This creature appeared by itself just beyond the edge of a wooden porch deck. It wasn’t looking very chipper–moving slowly, stumbling, crawling on leaves–so I offered it water and then honeywater in a saucer (which I feed troubled bees). It drank a little and then lost balance in the water and fell to the ground.
Not to worry, though, it went under the deck and emerged on the other side–twice–walking, not flying. This would be a total of around 16 feet of wandering.
I found it again about an hour after first spotting it, and it was on the steps kinda floundering, not totally upright and seemingly waving a few legs to get my attention, so I offered my finger and it rode on my hand while I got the camera.

Deformed Cosmosalia chrysocoma?

This all happened yesterday, I haven’t spotted it today.
I hope the photos show it well. What really got our attention were the exceptionally long articulated antennae, long body and tail that the insect curved up from time to time, and short wings.
In one picture, you can see the second set of legs up in the air like a surrender or a show of ferocity.

Deformed Cosmosalia chrysocoma?
Lion Beetle

Hi Juliette,
We have a guess for you, and we are going to request assistance from Eric Eaton to confirm or deny.  This is a Long Horned Borer Beetle or Longicorn in the family Cerambycidae.  Additionally, we believe it is one of the Flower Longhorns in the subfamily Lepturinae.  We believe we have identified it as Cosmosalia chrysocoma, a species with no common name.  According to BugGuide it can be identified by:  “The very dense, appressed, metallic golden pubescence is quite distinctive.
The puzzling component of your photo is what appears to be a deformation of the elytra or wing covers.  We aren’t sure if it is a natural deformation, or caused by trauma, or if perhaps they haven’t fully expanded due to recent metamorphosis.  We hope Eric Eaton can shed some light on this.

Comment with Correction
I don’t know North America longhorns but I’m sure that you identified it wrong because if the second par of wings is unharmed so I tried to identify it myself and I found that it might be a Lion Beetle – Ulochaetes leoninus at least according to bugguide http://bugguide.net/node/view/65020/bgimage.

Thanks mardikavana,
We appreciate the correction.  Seems it must not be such a common beetle if there is only one image on Bugguide.  We decided to do a bit more web snooping and Answers.com indicates:  “

Hi David,
In not too much time, we were able to identify your beautiful Flower Longhorn as
Stictoleptura cordigera on this website: http://www.cerambyx.uochb.cz/corcord.htmHere is another photo from the GEOLocations website.  Longhorn Beetles are also called Longicorns or Capricorns.  Your other insect is some species of Robber Fly.

Flower Longicorn: Pachyta armata

Dear Debbie,
We first posted an image of this unusual Flower Longicorn,
Pachyta armata, back in 2019 and we spent considerable more time trying to identify it originally.  There is not much information available on this species with no common name.  According to Montana Field Guides:  “We do not yet have descriptive information on this species.  Please try the buttons above to search for information from other sources.”  According to Jungle Dragon:  “This beetle is distributed in USA.”  BugGuide reports sightings along Pacific coast states and Canada.

Good evening,
I’ve attached three photos which i would like help with. The first, I think is an an mimic spider and would like to know what kind. The second, I think is a long-horn beetle but can not find specific information. And third, I found a pair of unusual insect “egg nests” (for lack of better term). If you can shed some light on what these are I’d appreciate it. Both were found on Lilac leaves.
Thank you!

Flower Longhorn: Leptura subhamata

Dear John,
As it stands, your request has three very different “creatures” you would like identified:  a spider, a beetle and a cluster of eggs.  To keep our classifications on our site from being too confusing, we limit our postings to a single species, or at least a single classification category.  With that stated, your Longhorn  appears to be
Leptura subhamata, which we identified on BugGuide, where it states:  “larvae host in decomposing Eastern Hemlock (Tsuga canadensis) and pine species (Pinus).”  If you still want additional information on your Spider and Eggs, please resubmit distinct new requests limiting your submission to a single species.

Thank you for your quick response and information on the beetle. My apologies for “clumping” my requests. I will resubmit for the spider. However, a friend (utilizing your site) identified the egg nest for me as that of a wheel bug.
Again, thank you for you quick help.
Regards, John

Letter 129 – Flower Longhorn: Pseudogaurotina cressoni


A moth and a beetle
What a wonderful site you have here! I’ve enjoyed looking through the pictures of bugs. A few days ago I saw a couple of beautiful insects in the mountains of BC, Canada, and I was wondering if you could help identify them. The moth I’m pretty sure is a snowberry clearwing or hummingbird moth, but my bug books didn’t have any beetles that looked exactly like the one I have here, which is large with very long antennae and a brilliant iridescent green. If you can help me identify them I’d be very grateful.
Alberta, Canada

Hi Jessica,
This is a Flower Longhorn. It resembles Gaurotes cyanipennis, but the dark legs and antennae on your specimen differ from the photos on BugGuide, so we wonder if it is a different species in the same genus. We will check with Eric Eaton.

Hi, Daniel: Took me a bit to research this one. The specimen in the image is Pseudogaurotina cressoni, nearly identical to Gaurotes, obviously! Both are truly spectacular beetles that are not uncommon on flowers in eastern North America. Eric

Letter 130 – Flower Longhorn: Stenelytrana emarginata


Coppery beetle in NY – brown prionid?
Here’s a bug that appeared on an old maple tree in central New York state. The size is what surprised us when it flew. It’s huge! I tried to identify it, and it may be a brown prionid, but only its back is bronze. The rest is black. The bronze sparkles in the sun. This was on your website. It has similar wings and antennae, but this one is all brown, and the one I saw was only brown on the wing covers. Can you tell what it is? Thanks! We love your site – amazing!

Hi Leslie,
Your beetle is in the same family as the Prionids, but a different subfamily. This is a Flower Longhorn in the subfamily Lepturinae. We believe it is Stenelytrana emarginata based on photos posted to BugGuide. Sadly, this gorgeous beetle does not have a common name.

It measures 2” or more in length and is found in certain native fig trees, in the branches and trunks of which its grubs feed. This beetle is a common species of the family Cerambycidae.”  It is also pictured on the Csiro Entomology website.  Your male specimen sure has some impressive antennae.

Letter 139 – Goat Insect is Capricorn Beetle from Paraguay: Steirastoma breve


Location: Encarnación, Paraguay
May 3, 2014 1:00 pm
Hi, my name is Clara Müller and I’m from Paraguay. One day, in February of this year I found this insect I’ve never seen before walking through my garden. So I wanted to know if anyone recognizes this kind of insect or knows the name of it. As you can see in the picture I took, it was light gray with little black dots with long horns and shiny eyes. It was like the size of a cockroach. It was wet and kind of hurt because of the rain. It looks like a “goat insect” to me. I’ve just seen it once and I’m curious.
I would be happy if you reply to this letter.
Thanks in advance!

Capricorn Beetle
Capricorn Beetle

Hi Clara,
While we do not have the time right now to research the identity of your Goat Insect, we can tell you what we do know.  This is a Capricorn Beetle or Longhorned Borer Beetle in the family Cerambycidae, and we never really understood why they were called Capricorn Beetles until we received your request.  Capricorn is the zodiacal sign of the goat and your Capricorn Beetle really does resemble a goat, so we think Goat Insect is a perfectly acceptable common name for your particular species, which we hope to be able to identify after we return to the office.

Goat Insect is Capricorn Beetle
Cacao Beetle

Update:  May 4, 2014
Hi again Clara,
We believe your Capricorn beetle bears a strong resemblance to the images of
Steirastoma breve that are posted on the Worldwide Cerambycidae Photo Gallery.  We found additional images on PaDil where it is called a Cacao Beetle and there it is noted:  “S. breve has been recorded as the most serious cerambycid pest of cocoa in the New World.”  Steirastoma breve appeared on a postage stamp from Argentina in 2002 and you may see an image of that stamp on Colnect.  There is also a nice image on FlickR that looks close to your Goat Insect, but part of the illusion is the camera angle and the shape of the head, which we cannot find duplicated in other images online.  There is one image that we located in a google image search, but alas, we cannot access the site at http://www.scielo.org.co/scielo.php?pid=S0120-04882008000200003&script=sci_arttext though we can see there is a reference to “La ‘gota’ del cacao, Steirastoma breve (Sulzer, 1776) (Coleoptera: Cerambycidae).”  We can’t help but to wonder if “gota” is a Spanglish name for goat, but that search has turned up a dead end since “gota” translates to “drop” or “gout” in English and “goat” in Spanish is either “chiva” or “cabra”.  We are not fully convinced that there might still be some relationship between the words “gota” in Spanish and “goat” in English, since searching the term “La ‘gota’ del Cacao” led us to yet another reference to the family Cerambycidae in the Biblioteca Naciional de Venezuela catalog and an article on Biblioteca Virtual – FUNDESYRAM that is specifically about Steirastoma breve.  Perhaps one of our readers with better Spanish language skills that our own can shed some light on this intriguing cross-linguistic word puzzle.

Hi Daniel,
Thank you for your fast response, I can see the resemblance in the pictures. There isn’t any cocoa plants in my yard or (I think) in my town, but I still believe this Goat Insect is one of them .. Since my native language is Spanish I can tell you for sure that the words “Gota” and “Goat” are not related, but I still wanted to know why it’s called like this. So I searched for “La gota del cacao” on Google and I found this website: http://www.fundesyram.info/biblioteca/displayFicha.php?fichaID=3798. There is some useful information for farmers who grow cocoa and how to prevent the damages caused by our little friend. They say that the most harmful things are the Steirastoma breve larvae because they eat the bark of the plant, cut its wood and cause the death of the plant. They also say that the larvae excrete a white liquid in little “drops” which makes easier for farmers to see them. (gota = drop).
If this information is correct I think we already have our answer. Anyway if you have another information to share I would like to hear it.
Thanks for your time and have a nice week!

Thanks for writing back Clara.  We really appreciate the etymological information as language, especially when translation is involved, can be quite confusing.

Great Capricorn Beetle

Dear Andrew,
This is a Longicorn in the family Cerambycidae, and based on images posted to Beetles from Romania, we originally thought it might be
Monochamus sartor, a member of the genus commonly called Sawyers, but additional research has caused us to rethink that and to conclude that it is more likely a Great Capricorn Beetle, Cerambyx cerdo, a mistake we have made in the past.  The images on iNaturalist were a strong factor in our correction.  According to a pdf from EU Wildlife and Sustainable Farming Project:  “The great capricorn beetle is a large beetle with a thin body and very long antennae which are longer than the body” and “The species is declining across Northern Europe but is still relatively common in South France, Spain and Italy. Nevertheless, even here, the rate of decline is worrying.”

Thank you for taking the time to examine the photos, cross-reference the sources and write such a detailed response. I command you for willingly answering the questions of so many out of passion. Your help is much appreciated.

What’s That Bug? turns fifteen today!!!
Dear faithful readers,
What’s That Bug? has several dates that we acknowledge.  We started as a column in the zine American Homebody in May 1998, and when the now defunct website American Homebody went live in 2001, we had our first presence on the internet.  See the history of American Homebody on Lisa Anne Auerbach’s site. We existed in that format for a year, and then on August 25, 2002, we registered the www.whatsthatbug.com domain, and this was our first posting as a unique website.  There was no image with that submission, and we found an image from the internet to use.  That launch date for our site predates the popularity of cellular telephones with the ability to take images.  Early submissions to our site required actual digital cameras to provide images.  Through the years, our mission has always been to educate people to appreciate and tolerate the lower beasts.  Interestingly, Longhorn Beetles, the category of that first posting, is still the most populated category on our site with 1012 postings as of right now.  Here is a gorgeous image of a Banded Alder Borer from our archives.

Hi Josh,
This is a Longhorned Borer Beetle in the subfamily Prioninae, known as the Prionid Beetles. While trying to identify it, we found this nice link to information on the Giant Fiji Longhorn Borer, Xixuthrus heros, with awesome vintage images of the indigenous people of Fiji eating the grubs.  Continued searching led us to a Wikipedia page on the Huhu Beetle, Prionoplus reticularis, and we verified that identification with other websites.  Like many other Prionids, the grubs of the Huhu Beetle are edible, and were considered to be a delicacy among the Maori, according to the TrekNature website.  The Huhu Beetle is the largest beetle in New Zealand.  To the best of our knowledge, the Longhorned Borer Beetles are not predators, and we are surprised at your claim that it fed upon a moth.

Hello there!
I was going through some pictures I took in New Zealand a couple of years ago, and came across an image of a large bug, which looked interesting at the time but which I never ID’ed. I’d love to know what it is.
It was just resting on the side of a building when I found it. I should mention this was in the middle of summer and the weather was quite warm and a bit humid; we weren’t out in the ”bush” or forest, but on a farm-like campground next to a National Park. This was about a 20-minute walk from the sea.
Any help would be much appreciated–I’m rather curious to know what this is!

HuHu Beetle

Dear M. Fullick,
The distinctive HuHu Beetle,
Prionoplus reticularis, is the largest beetle found in New Zealand according to the Te Ara Encyclopedia of New Zealand.  It is a member of the Longhorned Beetle family Cerambycidae and the grubs of the beetles in this family are borers in woody trees and shrubs.  Your individual is a female based on the presence of the pointed ovipositor that she uses to lay eggs in dead trees and posts.  The Tai Awatea government website has some marvelous information including that the beetles are attracted to lights.  The grubs are edible and were eaten by native Maori people.

Thank you very much! I’d definitely heard of the grubs (they’re famous in NZ), but had never seen the actual beetle until the day I took that picture. She must have been waking up, it was early evening when I found her.
Thanks again–cheers!

Kiawe Borer

Dear Verlan & Kristi,
This is a Kiawe Roung-Headed Borer,
Placosternus crinicornis, an invasive species in Hawaii.  Its larvae are wood borers that feed on Kiawe or Prosopsis, and ccording to Wikipedia, Kiawe or Prosopis limensis is a species of mesquite native to South America.  According to BugGuide:  “This beetle’s host plant, Kiawe (Prosopis pallida), is a tropical mesquite native to Peru, Ecuador and Colombia that was introduced to Hawai’i by a single seed planted in a courtyard in Honolulu in 1826. Kiawe spread to all islands and became a source of nectar for honey production, the abundant seed pods produced became fodder for a growing cattle industry, and the wood is prized for smoking meats and barbecue. The first Kiawe Round-headed Borer was collected in 1904. The beetles are attracted to felled trees and cut wood.”  Beetles with wood boring larvae frequently emerge from milled lumber many years after the tree that contained the larva was felled.

Dear Terro,
This is a Longhorned Borer Beetle in the family Cerambycidae, and larvae from this family bore in wood.  We are consulting with Eric Eaton to see if he agrees with us, but we believe we have correctly identified your beetle as
Pronocera collaris thanks to this BugGuide image.  According to Arthur V. Evans in his book Beetles of Eastern North America:  “Larva develops in spruce (Picea) and pine (Pinus).  Adults active in summer on flowers.”   Do you have a wood pile of pine or spruce or have you recently brought a pine or spruce piece of new furniture into your home?  The larvae might have been developing in the wooden item and then emerged inside your home.  Our editorial staff grew up in Campbell on the east side of Youngstown and we still visit several times a year.

Yes, we did bring some fire wood into the house a couple of weeks ago. After some research yesterday I decided to look and there is where they were coming from. We brought all of the wood back outside. Thank you for your response. My grandparents grew up on the east side as well!
Eric Eaton provides a different genus

This is a longhorned beetle in the genus Phymatodes, I believe.  That is a complex genus and I am not comfortable assigning a species (assuming my genus ID is correct).

Letter 155 – Long Horned Bee: Squash Bee


Ferocious bee
Hi Bugman!
Today I was examining my squashes when I saw this strange-looking bee. It has long antennae like a long horned bee, but its body doesn’t really look like one. It was traveling from squash flower to squash flower, but instead of drinking the nectar, it looked like it just wanted to sit in them. The bee itself looks oddly moody and temperamental, and it definitely acted aggressive whenever I tried to take a close-up shot of it. After taking the pictures I sent you, I tried to stick my camera into the flower to get a really nice shot, and I know that any insect would have been a bit annoyed, but this one, when I wasn’t even very close, launched itself out of the flower and body slammed my lens! I was pretty shaken after that, and I haven’t been able to find the bee since. But I would really appreciate finding out what type of bee it is, since I’ve never seen one before (I live in the San Francisco Bay area). Thanks,

Hi Brandon,
We believe this bee is in the genus Peponapis, known as Squash Bees. Squash Bees are Long Horned Bees in the tribe Eucerini, hence the resemblance.

Update: 906/29/2008)
Your identification of the squash bee is correct, and it is a male bee. Peponapis pruinosa is the likely species.

Letter 156 – Long Horned Bees. But why the aggregation?????


What kind of bees live in my garden, added location info
I will first tell you that I have taken it upon myself to see if I can identify these bees myself. I think they could be the European Dark Bee (Apis mellifera)(?) but the pictures don’t seem to match exactly. The habits of these bees is also very puzzling. In the evening these bees all congregate on my Miscanthus grass in my garden. They cling exclusively to two separate blades of grass and hang out there. They have not built any structure to live in and seem to have collected pollen for no reason at all. They do not seem aggressive but I still used caution taking these photos (that is why they are not very clear) because I am pregnant and thought it would be worth the effort to avoid getting stung by an entire group of angry bees. Can you help me identify these bees?
Thanks for checking into this, I hope this e-mail reaches you, I cannot open your websites home-page and have noticed that the latest request for ID was in ’05. Cheers,
Jessica Strickle

I see your website is up and running again and have also read through some of your scoldings to those who have requested ID. I am in Washington, IL (middle of Illinois) and these bees are about 3/4 of an inch long. If you get a chance to answer this, great! I just thought I might have a better chance with better information. Cheers,
Jessica Strickler

Hi Jessica,
First we feel guilty that you have called us on chastising (we like that better than scolding) our casual readership for not providing us with much needed information. We would never think to chastise you as your letter is so thorough. Yes, our website was down as we had internet connectivity problems, but our Time Warner serviceman, Tom, has assured us that the problem is remedied now. We believe, though we are not positive, that these are Mining Bees in the family Andrenidae. What has us curious is the social aggregation in a solitary species. We are going to request assistance from a true expert, Eric Eaton, on this.

Correction (07/29/2007)
Hi, Daniel:
The bees are all males in the tribe Eucerini (family Apidae), and probably the genus Melissodes, but I can’t be positive. They sometimes congregate like this to “sleep,” gripping a grassblade or twig in their jaws.

Hi Sandy,
We wanted to check with Eric Eaton on a species identification of your Long Horned Borer Beetle. Here are his conclusions: “Two possibilities: the spotted tree borer, Synaphaeta guexi, 12-20 mm, known to bore in maple; Neocanthocinus obliquus, 9-14 mm, which bores in pine. I am using a very old reference, so these insects may have different scientific names by now, I don’t know. There is no up-to-date reference for northwest beetles. Eric “

Hi Guys:
In examination of the photograph of the cerambycid from Costa Rica, it appears to be Psapharochrus circumflexus (aka Acanthoderes circumflexa). It, like so many insects, does not have a common name. It is very common in Costa Rica, and the larvae bore in many different freshly downed trees such as Cecropia. Hope this helps!

Longhorned Borer Pupa

Hi Courtney,
Your photo is of very low resolution, and when we enlarged it, the quality was further reduced.  We believe this is a pupa of a Longhorned Borer Beetle in the family Cerambycidae.  The family is often abbreviated as the Bycids.  Without knowing the host tree, it would be difficult to pin down a species, and some trees are host to numerous species of Borers.  A much clearer photo of a Cerambycid Pupa is posted to BugGuide.

Thanks very much for your work.  I wish our camera was better, but alas, ’tis all we have.

Longhorned Bees

Dear John,
These are neither Honey Bees nor Wasps, but they are Solitary Bees.  We are pretty confident these are male Longhorned Bees in the tribe Eucerini based on images posted to BugGuide.  Male Bees are incapable of stinging, and female Longhorned Bees are very reluctant to sting.  Since they pose no threat to your children, and since they are native pollinators, we hope you dispense with the insecticide.

Thanks so much!
I am glad I chose not to continue trying to eliminate of them this year … I originally had many problems with ants and had thought these were young queens, but this year I paused and looked closely and suspected it being a bee.

Hi Damian,

Hi Bugman
I have found 4 of these beetles (so far) in my bedroom, can you tell me what they are. These only started appearing after we had some Oak furniture delivered (made in China). It’s the only place I can think they came from. Should I be concerned, my wife already is.

Hi Bob,
This is a Longhorned Borer Beetle in the family Cerambycidae, but it is not the notorious Asian Longhorned Borer, Anoplophora glabripennis, that is a recent introduced exotic causing problems with native trees like maple and horse chestnut. It is possible it emerged from furniture or even firewood. We will see if Eric Eaton recognizes the species.

Predatory Katydid

Dear Sultan,
Though it looks like a Grasshopper and it is classified in the same order as Grasshoppers, this insect is actually a Longhorned Orthopteran in the suborder Ensifera.  Grasshoppers have shorter antennae.  We do not recognize the species, but we will contact Piotr Naskrecki from Harvard, an expert on Katydids, to see if he can provide a species identification for us.

Predatory Katydid

Thanks to a comment from Ben in Israel, we now know that this is a Predatory Katydid, Saga ornata, and FlickRiver has a nice photo.

Hi Daniel,
An impressive creature indeed. This is a male of Saga ephippigera, which I believe is considered to be one of the largest, if not the largest, Palearctic insects. These katydids are sit-and-wait predators, similar in their hunting technique to preying mantids.

Dearest Mr Bugman,
I am sending you these images of a peculiar insect I discovered in my bathroom tonight. It was just smaller than my palm, and very active. As someone with limited knowledge of insects, I have decided it is a grasshopper/wasp/Satan hybrid.
We caught it in the cup pictured and released it into our backyard. Not sure how it accessed the bathroom as all of our windows and doors are closed. Perhaps he snuck up the drain?
Myself and my father are extremely curious about what this little fella is! Perhaps a locust? Please help us, Bugman!

Raspy Cricket

Dear Pharaoh,
This is a Long Horned Orthopteran in the suborder Ensifera, a distinctly different group from the Grasshoppers which are also Orthopterans.  We suspect this might be a female Weta, a group distinct to Australia and New Zealand, though there are relatives in South Africa and California.  Her forward curving ovipositor is very distinctive, and you probably mistook it for a stinger.  We will contact Katydid expert Piotr Naskrecki in the hope that he can provide a more conclusive identification.

Thank you so much, Daniel! That’s fascinating – I’ve never heard of them before.  I would be intrigued to find out more about this particular one. It certainly gave me a bit of a fright in the bathroom!
Kind regards

Identification Courtesy of Piotr Naskrecki
Hi Daniel,
This is a nymph of Hadrogryllacris sp. (Gryllacrididae), not a weta (there are no true wetas in Australia) but a raspy cricket. The ovipositor is curved over the body in nymphs of raspy crickets to help them move backwards in shelters that they make of rolled up leaves. After the final molt the ovipositor becomes straight.

1st Ever Longicorn Beetle (Sawyer?) Sighting
Location: SE Michigan
July 5, 2011 5:48 am
Dear Bugman; Yesterday, I almost squashed this beetle by accident, when I went to turn on the outdoor faucet. I was so surprised to see that it was a Longicorn beetle–I had never seen one before! (And the only reason I knew what it was in the first place, was from photos posted on your site.)
I ran into the house and grabbed my camera before it disappeared.
It was quite calm, rather slow moving and allowed me to take many photos, as it rested on an aborvitae branch.
I am not sure, but I think it is a White Spotted Sawyer. Can’t get over the eyes, which wrap around the base of it’s antennae. He/she looks like a little alien from the profile.

Hi Christine,
Though we don’t know the identity of your Longicorn, we can say that it is NOT a White Spotted Sawyer.  We will enlist some expert advice and update this posting when we get an identity.

We used Arthur V. Evans book, Beetles of Eastern North America, where we found a similar looking Phymatodes amoenus pictured, and that led us to the related Tanbark Borer, Phymatodes testaceus, on BugGuide.  According to BugGuide, it is:  “native to Eurasia; widely established around the world, incl. e. US and, more recently, in the Pacific Northwest” and it feeds on Oaks with the larvae boring in the wood.  According to NatureSpot:  “The adults are active nocturnally and will come to light but are rarely seen otherwise under normal circumstances.”  Seems like you were tagged with the Bug Humanitarian Award for rescuing an Invasive Exotic species, another tag on our site.

We tried searching BugGuide, but we could not find a conclusive match.  We will continue to try to identify the species for you.  Your individual looks similar to
Acanthoderes giesberti from Cerambycidae Species Details, so we suspect it might be a close relative.  We will seek out an additional opinion.  We simply cannot resist posting identification requests with such positive subject lines like your “Beautiful bug!” subject and we agree with you fully that this Longicorn is a comely specimen.

Longicorn is Stenaspis solitaria

Dear JoLynn,
You are correct that this is a Longicorn in the family Cerambycidae, but we do not recognize the species.  We will post your image and hopefully get some input from our readers.  We will also contact Eric Eaton to see if he recognizes this lovely red bycid.

Cool!! Thank you!!! Can’t wait to hear what exactly it is!! We have lives here 4 years (in 38 acres) and have never seen one!

Longicorns are often very host specific.  Can you provide the names of the most common trees on your property?

Eric Eaton provides an identification
This is an unusual color form of Stenaspis solitaria.  Most specimens are completely black!  Texas has some populations that look like the one in the image here.

Ed. Note:
According to BugGuide:  “They love to fly around on hot days. Not common in so. TX but somewhat common in the Big Bend area and extremely common in so. AZ (Dan Heffern, pers. comm.)”

Letter 186 – Longicorn Beetle from Mexico: Callipogon senex


ID Stag Beetle in the jungle of Campeche, Mexico
December 20, 2009
Last week (December 2009) I was visiting some Maya ruins in Campeche, Mexico near the border with Guatemala.
I found this beetle, it seemed to be dying and was moving very slowly with its legs held close to it’s body.
Just interested to find out more about it,

Dear Tim,
This beautiful beetle is not a Stag Beetle, but rather a Longhorned Borer Beetle or Longicorn in the family Cerambycidae.  We believe it is Callipogon senex based on a photo on the coleop-terra website.  The species is found in Honduras and El Salvador as well as Mexico.  It was pictured on a postage stamp from Belize in 1995.

Hi Again Poppy,
Thanks for sending the much better resolution images.  This is definitely a Longicorn in the family Cerambycidae, and we are also confident that it is in the subfamily Prioninae, the Root Borers.  We are creating a posting and we will attempt a species identification, however, this will need to wait until later as we must dash off to work.

Hi Claudio,
This is a Longicorn or Capricorn Beetle in the family Cerambycidae.  We decided to search for its identity in a marvelous coffee table book given to us by Monika that is called Living Jewels, and we found a matching photo of
Steirastoma brevis, however, searching for that name on the internet did not produce any images of beetles with the bold black and yellow pattern of your beetle.  Our first hit online was an image of a postage stamp from Argentina on a site with Cerambycid stamps, but again, the color is not as bold as your individual.  You need to scroll down the page to find the alphabetized scientific name.  We then located an image on the Living Jewels site from the same page as our Living Jewels book image, but it is another member of the same genus, and we would not entirely discount that your beetle might be Steirastoma marmoratus.  A pale specimen is picture on Insect Life Forms.  Again, the colors are not as bright, and the spelling is different, but Steirastoma breve is pictured on BioLib.  Our favorite bit of information we found was of a fashion design blogger identified only as 1080741630 who was inspired to design a fabric print based on the markings of the beetle.  Scroll down to view the citation which reproduces the pattern but does not include an image of the beetle.  The blogger writes:  “I studied the beetle Steirastoma brevis for the brief ‘colour and patterns in wildlife’ experimenting with colour, texture and pattern. By contacting different fabric suppliers in New york, Paris and London, i was able to decide what fabric was best suited to my brief. From here I decided on marino wool for felting as the bold colour was so effective.”  We believe we have the genus identification correct, but the species name remains in question.  Perhaps Cesar Crash or one of our other readers will be able to provide additional information.

Your letter to the bugman:  In 25 years of visiting here, I never saw this bug before.  Now, after hurricane Irma, I see two or three every night. They are attracted to artificial light, and do not move much during the night.  The geckos and anole lizards leave them alone.  It is about an inch long.    I would be grateful for your identification, and your opinion about the idea that the hurricane could have altered their range, or even introduced them to this island. Thank you.

Longicorn:  Lagocheirus guadeloupensis

Dear RD,
This is a Longicorn in the family Cerambycidae, and we are pretty certain it is a Flat-Faced Longhorn in the subfamily Lamiinae.  We were not able to match your individual (the angle on the image might make identification difficult as a straight dorsal shot would be better) to any of the mounted specimens pictured on Cerambycidae de las Antillas, but we did find a reference to
Monochamus titillator, the Southern Pine Sawyer being found in the Bahamas in Tropical Zoology. and BugGuide lists the range as “e. US / Bahamas.”  For now, we will leave the species as unidentified.  Now, regarding its sudden, recent appearance, we don’t believe large numbers of this wood boring species would have been transported by Hurricane Irma.  We suspect many trees were downed during the winds.  If the wood was not cleared away, it would have provided a food source and it could possibly have resulted in a population explosion of a normally innocuous species.  This unidentified species from the Caribbean on FlickR looks very similar to your individual.

Update:  March 30, 2018
We just received a new submission and now we are somewhat confident that this individual as well as the new submission are both Lagocheirus guadeloupensis which is pictured on the Cerambycidae de las Antillas site, and we apologize for missing it originally.

It can be found in the West Indies, and from Mexico south to Argentina.”  Your images are gorgeous.

Your truly impressive beetle is a Longicorn or Longhorned Borer Beetle in the family Cerambycidae, and because of its resemblance to the Ivory Marked Beetle,
Eburia quadrigeminata, which is pictured on BugGuide, we suspect it may be in the same genus.  Since we must dash off this morning, perhaps one of our readers will be able to provide us with a species identification.

Hello Daniel, I think I have this one pegged (so to speak). I was detoured by the tanbark borer but it was not quite right so I kept looking, finally coming up with Longhorn Beetle Cerambycidae Certallum ebulinum ruficolle Fabricius (but not sure all those designations are needed because I do not know what they all mean…).

Longicorn:  Certallum ebulinum ruficolle

Hi Curious Girl,
Using the name you provided, we found a nearly identical image on a Cyrillic language Coleoptera page and an image of a mating pair on Biolib.
  Regarding the name, Cyrambycidae is the name for the family.  The next three words are the taxonomic name for the genus, species and subspecies.  Fabricius is the authority credited with first publishing the name, and that should be followed by a year, which in the case of this beetle is 1781.  Longicorns are often called Capricorns, but we personally generally reserve that for larger species.

Thank you. I will try to get a better photo, but I seem to have wasps hanging out in the corn also. Do they damage the corn?

Wasps might be hunting for caterpillars and we doubt they are damaging the corn.  We decided to take a second look at your Longicorn, and we found a posting in our archives of Trachyderes succinctus that shows the black and red striped antennae as well as the body markings that are shared with your individual.  A second posting in our archive of Trachyderes succinctus from the Virgin Islands includes this observation by the person who submitted the images:  “It likes rotting fruit but absolutely loves to go after young corn. It nibbles away at the base of the ear, leaving a blackish goo and killing the ear. It decimated my back yard corn crop a couple of years ago and I have not been able to replant successfully since.”

Thank you so much….

Letter 197 – Longicorn feeding on Pecan Tree in Florida


Subject: Beetle in Pecan Tree
Location: Orlando, Florida
May 27, 2014 6:53 pm
I found this beetle in our old Pecan tree that has been on it’s down side for a few years now. There are at least 4 dozen holes around the bottom of the tree extending upwards 6-7 feet. The beetle does not like sunlight and does not like light from a bulb flashlight but is ok with an LED flashlight.
The antennas are long, 2″ or so and the pincers are black and hard. When I tapped the antenna of one with a piece of paper it went back into the hole and folded back it’s antenna then came forward with it’s pincers. When I touched the pincers with the paper it grabbed it and gave it a tug as if to take it into the hole.

Longicorn emerges from hole in pecan tree
Longicorn emerges from hole in pecan tree

Dear Don,
We probably cannot determine an exact species based on your image, however, your detailed description indicates that this is a Longhorned Borer Beetle or Longicorn in the family Cerambycidae.  Larvae are wood borers, and often spend several years feeding on wood prior to emerging as adult, winged beetles.  Longicorns are not general feeders, and each species has a single or several preferred host plants, and most do not infest healthy trees.  Your letter indicates this tree has been in decline, and that is likely the reason that wood boring insects have begun to feed on it.  Your description and image indicates that this is an adult beetle and it should soon be exiting through the hole it bored to the surface.  Once they leave the larval burrow, they will not return, though we would not discount the possibility that a female might enter a hole to lay her eggs.  Based on knowing the host plant is a pecan tree, we will attempt an identification, but if you really want a species identification, we would suggest that you capture a beetle and provide us with a dorsal view. The Texas A&M University Entomology site’s Insect Pests Attacking Pecan in the US page lists 15 Longicorns that feed on the wood of pecan trees.

Hello Daniel,
Thank you for your reply. It was difficult to get a good picture so I’m happy the description helped.
Is there any action that we should take to eliminate the beetle before we have the tree remove?
Thank you in advance,
Don Schenck

You can leave the cut wood on site and allow the beetles to develop.

From your website, I see it is a long-horned beetle, and by checking a webite you had recommended to someone else, I have narrowed it down to batocera rufomaculata.

Hi Linda,
We agree with your genus identification of
Batocera, however, when we posted an image of mating beetles in the genus Batocera from China back in 2009, our frequent contributor Karl provided information on the two species that range in China:  “There are several similar looking species in Asia, but as far as I can tell only B. davidis and B. rubus occur in China.”  There is often individual variation in the coloration of insect species.

Permaculture in Brittany


Dear Permaculture in Brittany,
We were not familiar with the Cardinal Beetle, so we researched it.  It is a Fire Colored Beetle in the family Pyrochroidae.  Your beetle is a Longhorned Borer Beetle or Longicorn in the Family Cerambycidae.  We located a website of Longicorns from France, and we believe your beetle is
Corymbia rubra.  The following information is provided in the Lepturinae subfamily page:  “Vit sur troncs abattus de conifères, saules et fleurs, visible d’Avril à Juillet  La femelle est plus grande que le mâle qui a un pronotum noir  Larves dans les troncs de conifères morts   Tribue des Lepturini” but alas, we do not speak French, but perhaps our website’s translation feature will crack the code.  The Garden Safari website discusses the sexual dimorphism of the species, and that indicates the coloration of your specimen makes her female.  The Garden Safari indicates:  “With the majority of beetle species the male and the female are almost identical. In a few exceptions, however, there are striking differences between the two genders. This is the case with Corymbia rubra, a species quite common on flowers in the gardens. The male is slender, brownish and has a black neck shield. It seldomly reaches a length of over 15 mm. The female is bigger and more plump, reaching some 20 mm in length regularly. Her body is reddish, including the neck shield. Actually they do look like two completely different species! This particular species is very rare in the UK because the plants the larvae feed on are not indigenous in Britain. It is still often referred to by either of its former scientific names Leptura rubra or Stictoleptura rubra.

Very many thanks for your comprehensive reply, Daniel.  I’ve posted your help on our blog  http://permacultureinbrittany.blogspot.com/ .  I’m getting more interested in beetles, especially dung beetles with regard to pasture improvement, so shall keep visiting your site but not bothering you too often with questions.  I might treat myself to your book when it’s published too.

The only matching image we were able to locate is this Indian Longicorn from our own archives, and eight years ago, Karl wrote in suspecting it to be in the genus
Batocera, though unfortunately the link Karl provided does not seem to be active any longer.  We will continue to search for a genus or species verification on your lovely Longicorn.

Correction courtesy of Karl
Hi Daniel and rastaPoPoy:
It looks like this longicorn and the one from your archives are indeed the same species. Although I previously suggested that it might be a species of Batocera, it seems I was on the wrong track. In checking again I am now going to suggest that this lovely beetle is Olenecamptus bilobus (Cerambycidae: Lamiinae: Dorcaschematini). The species is widely distributed throughout Asia and Melanesia, and comes in a variety of colour variations. Two  subspecies occur in India; O. bilobus bilobus and O. bilobus indianus. The two subspecies are quite similar and your two postings could belong to either one. Here are some additional images from Assam and the Seychelles.  Regards  Karl

Hello again Kiran,
The best we can do at this time with this identification is to provide a family.  This is a Longhorned Borer Beetle or Longicorn in the family Cerambycidae, but we are not certain of the species.

Dear Naveen,
This is truly an impressive Longicorn, and its antennae are amazing.  We did not find anything similar on Prioninae of the World, but we might have missed it.  We will continue to attempt a species identification for you.


Update:  Cesar Crash of Insetologia sent a comment that identifies this beautiful male Longicorn as being in the genus Neocerambyx, and this image of Neocerambyx paris on Cerambycoidea Forum looks very similar.


Letter 213 – Longicorn from Israel


Asphodel longicorn?
February 14, 2010
Hi Bug People!
I found this longicorn beetle on some Common Asphodel flowers on Friday, Feb 12th, in the northwest Negev, Israel.
I saw a few of them during the day, but only on the asphodels.
Some research led me to believe this is Agapanthia pustulifera.
I also found a true bug on the asphodels, which I will send in a separate mail.
Northwestern Negev, Israel

Longicorn:  Agapanthia pustulifera

Hi Ben,
You have saved us the effort of identifying your Longicorn.  We found a photo of Agapanthia pustulifera on BioLib, and we agree that it matches your beetle.

Thank you for submitting your identification request.
Please understand that we have a very small staff that does this as a labor of love. We cannot answer all submissions (not by a long shot). But we’ll do the best we can!

I understand, no problem.  it looks like a kind of wood boring beetle but I can’t find any information on native Italian species.
many thanks and love your site!

Longicorn: Morimus funereus

Dear Alexa,
You are correct that this is a Longhorned Borer Beetle or Longicorn in the family Cerambycidae, and we identified it as
Morimus funereus on the Worldwide Cerambycidae Photo Gallery.  In a posting from Macedonia earlier this year, we learned it is a Red Listed Species on the IUCN site devoted to threatened species.

Dear Ijah,
This is a Longicorn or Longhorned Borer Beetle from the family Cerambycidae, and the larvae of members of this family are wood boring insects.  It might be

Hey Daniel,
Thank tou so much for your early response. You have busted my bubble on hoping to have found a new species of bug , but atleast i and my neighbors are now more educated on this matter. We were very fascinated by the interesting look and fearlessness of the insect.

Dear YS,
All we can say for certain at this time is that this is a Longhorned Borer Beetle in the family Cerambycidae, and that they are sometimes called Longicorns or Capricorns.  The larvae are wood boring insects.

Hi Ben,
This is a Longicorn or Longhorned Borer Beetle in the family Cerambycidae.  As you have probably noticed, there is often difficulty identifying African bugs to the species level as there are not many websites devoted to them, unlike North American, Australian and British bugs.  We believe it might be
Tithoes confinis which we found on the Worldwide Cerambycidae Photo Gallery and which is also represented in our archives.  Perhaps someone with more experience will write in to confirm our identification or correct it.

Longicorn: Dorcadion ariannae

Dear Wiliam,
This is a Longicorn in the family Cerambycidae, and we wish you had a more detailed image.  We started searching for what we though was going to be an easy identification because that white “racing stripe” adorning your Beetle’s back is so distinctive.  Our first clue came on the New World Cerambycidae Catalog where we found
Dorcadion regulare pictured, but it has red legs, unlike your individual.  We then found members of the subgenus Cribridorcadion pictured on the Cerambycidae of the World page, and several members of the subgenus look very similar.  Back on the New World Cerambycidae Catalog site, we found Dorcadion ariannae pictured, and it is the closest visual match, in our opinion.  Islands frequently have species and subspecies endemic to the island that are different from close relatives on the mainland.  We did find some mounted specimens in the genus available on eBay where it notes:  “Dorcadion ariannae (Greece) – RARE” but alas, there is no image of the species, while images of relatives are pictured.

Many thanks for the information.
This one seems quite a challenge!
I have reprocessed the image and added another in the hope they will give you more information,
Your help is much appreciated,
William Smiton

Letter 220 – Longicorn from New Guinea may be Batocera kibleri


Some more great bugs from PNG
April 30, 2010
There are so many awesome bugs here in Papua New Guinea, and I know we’ve only seen the tip of the proverbial iceberg. Here are a few we thought you would like to see.
The first is called, at least locally, a “Christmas spider.” Perhaps you can identify it? They’re rather small – the largest being only about an inch across. The second, some kind of leaf bug? It was about 3″ long, not including antennae. The third, a borer, also about 3″ long not including antennae, which had a spread of about 8″. The spider and leaf bug were photographed near Madang and the borer was photographed in Buka, Bougainville. Enjoy!!

Letter 221 – Longicorn from Nigeria


Subject: ”Well there is something you dont see every day”, I said to myself.
Location: Bonny Island, Niger Delta, Nigeria, West Africa.
November 14, 2012 11:34 am
May 2008 – This was the beast that started it all for me; sheltering from the rain on the underside of a leaf in my garden in, of all places, the Niger Delta on Bonny Island, Nigeria. It certainly wasnt happy when I tried to move it to a better perch for its first photo shoot. It actually sqeeked!
It appears to fall into Longhorn territory but I cant find any other image of it. I would dearly love to know if it has a name. At 50mm long, excluding ”horns”, it is a magnificent creature. You can see how the psyche of science fiction writers would make their imagination run riot. If only I had time to go on a bug hunt here in Thailand.

Hi Bill,
We haven’t had any luck with an identification on this beautiful Longicorn in the family Cerambycidae.  We are posting your photo and we hope to have it identified before too long.
  We especially love the photo where this impressive Longhorned Borer Beetle is attempting to take flight.



Hi Daniel…
Just downloaded the Electronic version of your book to my iPad… thumbs up to that!
Glad the Longicorn is a new animal for the team… and thanks for posting it.
It made several attempts to fly off until I finally let it go.
Some of the locals were showing a bit more white in their eyes as it soared up into the massive Jungle trees on the other side of the perimeter wall.
There are one or two other unidentified “monsters” on my hard drive for you to get your teeth into.
When I find the images of Bert and Jimmy having breakfast, two huge black and orange Assassin bugs, I’ll share them with an amusing story over their sad demise to an Great African Water Diving Beetle.
Which, apparently, is the biggest “bug” in the world –  Can you confirm that?
Very much appreciate the time you devote to it all.
Thanks for doing what you do.

Longhorned Borer Beetle

Hi again Bill,
We hope you enjoy the book and we look forward to your other submissions.  We believe you are mixing up Diving Beetles with Giant Water Bugs or Toe-Biters as they are known in the U.S.  Southeast Asian Giant Water Bugs are reportedly the largest True Bugs on Earth.

Karl provides the identification of Ceroplesis adusta.
Hi Daniel and Bill:
Your longicorn looks like a species of flat faced-longhorns (Lamiinae), probably Ceroplesis adusta. It is widely distributed throughout East Africa, but I couldn’t find out much more about it. Regards. Karl.

Thanks for the assistance Karl.  Your input is always greatly valued.

Unknown Longicorn

Dear Nana JoGoFe,
We can tell you that this is some species of Longicorn or Longhorned Borer Beetle in the family Cerambycidae, however, our initial internet search has not turned up any matching images from Puerto Rico.  Perhaps one of our readers will be able to assist in a species identification.  For now, a family will have to suffice.  The coloration is quite distinctive, and we don’t believe a proper identification will prove entirely elusive.

February 5, 2012
Hi Daniel and Nana JoGoFe:
It appears to be a longicorn in the genus Chlorida, probably C. festiva. It is a very wide-ranging species found from southern Florida to Argentina, including much of the Caribbean. Regards. Karl

Thanks Karl,
We suppose the genus name
Chlorida refers to the green coloration.  We also found a nice image on American Insects.

Dear Adam,
We did a quick search and could not come up with a species, but we can tell you that this is a Longhorned Borer Beetle or Longicorn in the family Cerambycidae.  We will continue to research its identity, and perhaps one of our readers (Mardikavana are you out there?) can assist in the identification.

Update:  August 22, 2015
We received a submission of a Longicorn from the UK today that we identified as a Musk Beetle,
Aromia moschata, and we believe this is the same species.  Some variations in coloration are posted on Eakring Birds.

Longicorn: Tithoes confinis

Dear Robin,
You are correct that this is a Longicorn in the family Cerambycidae.  We found a matching image on the PicClick website that is identified as
 Acanthophorus (Tithoes) confinis, and upon searching for that name, we found an individual for sale on Ebay for $450.00 which indicates this must not be a very common species.  The large mandibles indicates that this is a male, and we have an image of a female Tithoes confinis in our archives.  According to iNaturalist:  “Tithoes confinis can reach a length of 55–100 millimetres (2.2–3.9 in). This beetle has a massive hairy body and strong mandibles. The basic colour is dark brown. Pronotum bears two spines on both edges. Adults are nocturnal. Larvae feed on Cashew Nut Trees (Anacardium occidentale) and other trees belonging to the Anacardiaceae family.”
