Bug of the Month July 2011: Broad-Necked Root Borer

Ed. Note: We have never made any of the Prionid Beetles a Bug of the Month, and summer is the season for the various species from coast to coast.  California has the California Prionus and the Eastern states have the Broad Necked Root Borer.  Many Prionids exhibit distinct sexual dimorphism, with the smaller males having more pronounced antennae.  Many females are practically or totally flightless, and males are attracted to lights at night.  Here is a recent letter.

I don’t think I’ve seen a bug this big in New York before. It’s slowly walking around my sidewalk and sticking its butt up in the air like this, with a yellow thing that is protruding and retracting.

Hi J,
Your insect is a female Broad-Necked Root Borer,
Prionus laticollis, and the yellow thing is her ovipositor which is used to lay eggs.  According to BugGuide:  “Eggs are inserted into ground (or under litter) in groups. Larvae tunnel downward to feed on living roots of a variety of trees and shrubs. At first they may feed on bark, but then proceed to hollow out small roots.”

Bug of the Month June 2011: Tachinid Fly

Ed. Note:
May 29, 2011
Though this letter was submitted nearly a year ago, we discussed with Frederique Lavoipierre the possibility of making the Tachinid Fly the featured Bug of the Month for June 2011.

What is this bug?
Location:  Cloudcroft Observatory, New Mexico.

Hello. I was curious about a bug I saw in the mountains at Cloudcroft, New Mexico. This bug was found at the Cloudcroft Observatory. It seemed a lot like a bee because it buzzed, but it looked totally different than one.
This bug was seen in August, 2010.
Thank you!

Tachinid Fly

Hi Carly,
The color palette of your photograph is so beautiful.  This is a Tachinid Fly, probably
Adejeania vexatrix based on images posted to BugGuide.  Adult Tachinid Flies take nectar from flowers, but immature larvae are endoparasites on a variety of insects and arthropods, often limiting themselves to a single species.

Bug of the Month
May 29, 2011
We are taking this opportunity to make our readership aware of the beneficial flies in the family Tachinidae by linking to the BugGuide information page on the family.  We are also providing a link to the Pacific Horticulture website and the online article on Tachinid Flies submitted by Frédérique Lavoipierre, Garden Ecologist. Here is an excerpt from that article: “Tachinids are the most diverse family of Diptera (true flies), and help control many pests; of the parasitic insects, only parasitoid wasps are of greater importance. All of the known species of tachinids are parasitoids: they deposit their eggs on or near host arthropods, and the larvae parasitize the host, in most cases resulting in the victim’s death. Parasitoids (as opposed to parasites) are free-living as adults; many of the common garden tachinids are flower visitors, feeding on nectar and pollen as adults. Tachinids parasitize a broad range of hosts from several orders of insects, among them Lepidoptera (butterflies and moths), Coleoptera (beetles, especially scarabs and leaf beetles), and Orthoptera (grasshoppers and crickets). In the Hymenoptera (wasps, bees, and ants), they specialize on sawflies, a common herbivorous pest. They are also known to attack a few other arthropods besides insects, particularly centipedes.”

Update: June 29, 2011
Hi Daniel,
Took me a bit longer than I thought to wrap up my thesis, and someone in the department just pointed out the tachinid ‘bug of the month’ to me yesterday. At any rate, it was very cool to see tachinids in a starring role!

Although I was able to identify these with the help of your fantastic website, I thought you might like to see the pictures I took today since not much is known about these beetles. They are in one rosy buckwheat subshrub by the HUNDREDS (and from a closer look at the photos, ensuring future posterity with gusto). I was very relieved to affirm they are beneficial insects. Thank you so much for all your hard work!

Mating Brown Leatherwings

Hi Colleen,
Thanks for your kind compliments and your awesome photos of Brown Leatherwings, formerly
Cantharis consors.  They are attracted to our own porch lights each spring and we have been meaning to document their activity because it seems to us their numbers are more numerous this year.  We also thought of making them the Bug of the Month for May, but in an impulsive moment, we decided to feature a Black Click Beetle instead, but we are having second thoughts.  We have decided to demote the Black Click Beetle from the feature section and replace it with your submission.  Here is what Charles Hogue wrote of the Brown Leatherwing in Insects of the Los Angeles Basin in our second edition from 1993:  “Adults frequently come to porch lights in the late spring (April to May).  They give off a strong unpleasant musty odor when handled or crushed and may also exude a yellow fluid.  Little else is known of the habits of the adults, and the early stages remain undescribed.  Both are probably ground dwellers that live in plant litter and prye on other insects.”  BugGuide provides the taxonomic change to the name, now accepted as Pacificanthia consors, but there is little information on the species nor is there a common name listed.  BugGuide does provide somewhat more information on the family page, including:  “Adults mostly on vegetation, often on flowers; larvae in leaf litter, loose soil, rotten wood, etc” and  “Adults eat nectar, pollen, other insects; larvae are fluid-feeding predators, feed on insect eggs and larvae.”  More detailed information on the Brown Leatherwing may be located at the Pacific Horticulture website.

Dear Bugman,
I am amazed, and appreciative, at the speed with which you were able to reply to my email, and am honored that you chose to post the pictures.  Bug of the month, Woo-whoo!  Just this past weekend we had over 400 people through our suburban garden as a part of the east bay “Bringing Back the Natives” tour, we (a neighbor and fellow native garden enthusiast and I) were also interviewed and spotlighted in the local paper.  But I have to say, being posted on WTB bests it all.  Huge Fan!  Thanks!

How delightful to find my article on soldier beetles featured on one of my favorite bug websites! No worries about copyright infringement with all those links to Pacific Horticulture Most of my Garden Allies articles are available online – hey, how about tachinid flies for ‘insect of the month’? If you want to see the first four articles, I can email text, or there is a booklet available with the first dozen Garden Allies articles and articles on creating habitat for beneficial insects ($10). Proceeds benefit the Sonoma State University Entomology Outreach Program.

Hi Frederique,
Thanks for the compliment.  The next time a beautiful photo of a Tachinid Fly is sent to us, we will prepare a Bug of the Month feature at your suggestion.  The texts you are offering would be an excellent addition at that time.

The tachinid article, like the soldier beetle article, gathers together information that is rarely available to the general gardening public. The expert on tachinids who I consulted (all my articles are vetted by specialists in the field), John Stireman, was thrilled beyond measure that tachinids were going to get some popular press exposure. I will work on my tachinid photography; I see them on my insectary flowers all the time.
Here’s a link to a beautiful tachinid in my garden – not at all the typical bristly specimen!

Bug of the Month May 2011: Unknown Black Click Beetle

April 29, 2011
Last night while posting to the website, Daniel felt something crawling on his neck, and it was this gorgeous large black Click Beetle.  This is the second time this beetle has been found in our Mt Washington, Los Angeles offices, and the first sighting was almost exactly two years ago.   Recently while planting walnuts in nearby Elyria Canyon Park, a large Wireworm was uncovered in the dirt.  Sadly, there does not seem to be a match on BugGuide.  Species in the genus
Lanelater are not listed in California on BugGuide, and we thought we might have an identification with the California species Melanectes densus, but that species seems broader with different antennae than our little beauty.  It seems a bit tragic that we are unable to identify our own species of Click Beetle, but perhaps Mardikavana or one of our other beetle aficionados will be able to provide an identification.

We kept this beauty on the kitchen table under a glass until there was natural morning light for an indoor portrait and we later release it after taking some outdoor images as well.

Hi,
Every spring and summer I find these in our garden and would love to know what type of insect it is. Most recent find was on 3-26-11 on a Japanese maple, but I have found them on Lantana and also just hanging out on on the fence. I never see any feeding damage on the plants the looper is on. Thanks!

Inchworm

Dear Sharon,
At the moment, we are only going to be able to provide you with a very general Family identification, which you may already know.  This is an Inchworm or Spanworm or Measuringworm in the family Geometridae, and browsing through BugGuide will reveal many similar looking caterpillars.  Inchworms are also sometimes called Loopers, though not all Loopers are in the family Geometridae.  The Inchworm gets its common name because of its manner of locomotion, which your photo beautifully illustrates.  Most caterpillars have five pairs of prolegs, but Inchworms have only two pairs, which results in the caterpillar walking forward with the fore part of the body in a typical manner, and then looping the rear portion of the body to catch up, causing the larva to appear as though it is measuring distance as it moves.  Your second photo demonstrates the marvelous camouflage ability these caterpillars have for mimicking small twigs.  We are not certain what species of Inchworm you have submitted, but we suspect the species found on the Lantana might be different from the individual you found on the maple.  Many Inchworms look very similar and they are difficult to distinguish from other members of the family.  Since it is the end of March, it is time for us to select a Bug of the Month for April, and we love your photos so much, we have decided to give your Inchworm that honor.  With the dormant trees beginning to produce tender leaves in many parts of the country, young caterpillars will start appearing as well to feed on those leaves.  The vast majority of our caterpillar submissions occur in the fall when large fully developed Caterpillars leave their host plants to find places to pupate, but sharp eyed observers will be able to find Caterpillars in the spring as well.

Hi Daniel!
I am absolutely thrilled (can’t stop smiling) that you have chosen my submission as worthy for BOM! I am a “wannabe” entomologist, to the point that I lead the introduction to entomology for my county’s Master Gardener training class. I am a certified Master Gardener and photography is another of my hobbies. I hope to culture this inchworm through to its adult stage (to help in the identification). I have tried before, but my captive conditions do not seem suitable for success. Perhaps a larger terrarium with native soil will help.
And thank you for the lesson on inchworm definition (vs. caterpillar), I will share this information with my Master Gardener peers and trainees! Thank you, again!
Cheers!

Good morning! When I arrived at our warehouse this morning, there were a few dozen of these moths on the north exterior wall. Our warehouse is located in Huffman, TX, which is on the Northeast side of the greater Houston metro area. After searching, they appear to be Luna Moths, but I have never seen them before. We have had relatively dry weather as of late, and these pictures were taken around 8:00 a.m. on Monday, February 28th. They also appear to be quite lethargic. Are they spawning now?

Luna Moth

Dear Thad,
We are very excited about your email for several different reasons.  First, we want to congratulate you on what must be a spectacular sight.  We imagine much of our readership as well as our editorial staff are quite envious that you witnessed dozens of Luna Moths at one time.   Since it is time for us to select a Bug of the Month for March, we cannot think of a more fitting candidate than the Luna Moth, even though it has received the honor of being Bug of the Month once before, nearly four years ago in April 2007.  Luna Moth sightings typically begin in February in the southernmost reaches of their range in Florida, and as spring progresses, sightings appear in the more northern climes, generally peaking in May for Maine and Canada.  Luna Moth adults do not feed and they have a very short lifespan.  Adults mate and lay eggs and quickly die, so if you have swarming Luna Moths, they must be spawning.  Thanks for getting our day off to a wonderful start.

Luna Moth

Daniel,
Thank you for the quick response.  As I’m sending you this email, two more of them just landed on my window.  Having grown up in Austin, TX, I had the good fortune of seeing the annual Monarch butterfly migration.  It’s quite a sight to see thousands of Monarchs together.  Here in Houston, the Natural Science Museum has a butterfly exhibit, which allows you to see the cocoon hatchery as well as an enormous walk through controlled environment where several species of butterfly and moth fly all around you.
Do you have a good source where I can find out what other “rare” species of moth are in this area?  We have also seen some interesting moths in the College Station are which, at first glance, we thought were hummingbirds.  Do you happen to know what these might be?  They moved very quickly, and were about the same size as the Luna.

Hi again Thad,
Though our category states that the Luna Moth is a rare species, that is not entirely true.  Some local populations, like yours, are apparently quite plentiful, though in other parts of their range, Luna Moths are quite rare.  The other moths you describe are probably Sphinx Moths in the family Sphingidae.  You can try to identify the species you saw on the Sphingidae of Texas webpage.

Hi again Jack,
We just fired off a quick response to you because we didn’t have time to write a lengthy posting before rushing out of the house to save the Southern California Black Walnut (Juglans californica) Woodland.  We love your one photo of the Muskmare and mate and we couldn’t think of a more romantic photo in recent memory that could serve as the Bug of the Month for February when it will run as a feature on our front page.  Some species of Walkingsticks or Phasmids reproduce parthenogenetically, meaning that young female Walkingsticks can develop from unfertilized eggs so they are genetically identical to the mother.  This is an example of a natural clone and it produces a race with no genetic diversity.  Your Muskmares or Two Lined Walkingsticks,
Anisomorpha buprestoides, are capable of spraying a noxious fluid from the leg joints with amazing accuracy.  There are numerous accounts of them spraying the unwary right in the eye.

Daniel,
I do have more pictures from different angles and at a better resolution if needed. I’d be honored to have the picture posted as bug of the month.

Send a few more images and we will see if we need to update the posting which already looks great.  It will undergo minor alteration for the Bug of the Month.

Bug of the Month January 2011: Small Winter Stoneflies and Definition of Infestation

Need to Identify
Location: Northeastern Pa.

We have had an infestation of these bugs since early November. Have no clue what they are and have searched all over online but have not yet found a match. Can you please help us identify them?

Small Winter Stonefly

Dear desperate,
You have Small Winter Stoneflies in the family Capniidae and we are really looking forward to the opportunity to educate you regarding the complexities of the web of life on our fragile planet and to hopefully nurture an appreciation of your own unique ecosystem in Northeastern Pennsylvania.  We should start with a definition of “infestation” and for that, we are turning to our Webster’s Unabridged Dictionary that accompanies our Encyclopaedia Britannica.  “1:  the act of infesting … :  Plague, annoyance  2:  something that infests:  swarm … 3:  the state of being infested esp. with metazoan parasites in or on an animal or plant body.”  The dictionary goes on to define “infest” as “1 archaic:  to attack or harass persistently :  worry, annoy  2a:  to visit persistently or in large numbers  :  overrun, haunt …  b:  to live in or on as a parasite –used esp. f metazoan parasites of animals.”  At any rate, “infestation” has a negative connotation and though you may not understand how these Small Winter Stoneflies play a part in your ecosystem, and though you may be annoyed with their presence, they do not constitute an infestation.  They will not harm you, your pets, your home or its furnishings.
According to BugGuide, the “family is distributed throughout much of North America but many species have restricted geographic ranges, and are endemic to relatively small areas.
“  That means that you might have a unique species that is endangered.  The fact that there were enough individuals to spark your concern is indicative of a healthy population.  Additionally, Stoneflies have aquatic larvae that cannot survive in polluted waters.  The presence of a large quantity of adult Small Winter Stoneflies in your area is indicative of a nearby pure water supply.  A healthy population of Stoneflies are actually an indicator that there is a healthy and diverse ecosystem in your area.  This past March, we selected Winter Stoneflies as our Bug of the Month and that resulted in a request from the Xerces Society for Invertebrate Conservation.
Because we feel so strongly about the preservation of the environment as well as promoting an appreciation of the lower beasts, we are selecting your letter and images as our featured Bug of the Month for January 2011 even though Winter Stoneflies have occupied that position of distinction on our website in the past.

Small Winter Stoneflies

I so appreciate your e-mail and sharing of knowledge on these Small Winter Stoneflies.  I understand that ‘infestation’ has a negative connotation and I didn’t mean for it to come across as negative although they are “visiting persistently and in large numbers” and are often falling from the ceiling  of our basement or siding of our house onto our bodies or into our hair.  The backside of our house is literally covered in them and you can’t come in the door without a few making their way in as well.  Nonetheless, I’m very happy to learn that they are not harmful to us, our pets, or our home. We do have a seasonal creek that runs back behind our house, so I’m wondering if that is the source of “unpolluted” water they are being attracted to?
Again, thank you for your time in helping us to identify this insect and learn more about them! We’ll tread more carefully from here on out…
The Becks in Pa.

The creek sounds exactly like the habitat needed for the larvae to mature in an aquatic environment.  Stoneflies live in running water, not standing water.
