The soldier beetle is a fascinating insect that you might have come across in your garden or nearby fields. These beetles play several crucial roles in the ecosystem, such as pollination and helping to control various pests. In this article, we will provide you with essential information about these intriguing creatures, so you can better understand their behavior and significance.
Adult soldier beetles are generally about ½ inch long and can range in color from yellowish to tannish-brown, with soft wing covers. They have a black head, black legs, a black spot behind the head, and an oval, black spot on each wing cover link. Often referred to as “leatherwings” because of their soft, cloth-like wing covers, these beings come in various shades from yellow to red, with brown or black wings or trim link.
As you continue to read, you’ll learn more about the life cycle, behavior, habitat, and other noteworthy aspects of this charming little beetle. Armed with this knowledge, you’ll be able to appreciate the valuable contribution that soldier beetles make to our environment and garden ecosystems. So, let’s dive into the captivating world of soldier beetles and discover all you need to know about them.
What Are Soldier Beetles
Soldier beetles belong to the family Cantharidae and are often seen in gardens, fields, and forests. They play an important role in controlling pests, which is beneficial to gardeners and farmers.
There are various species of soldier beetles. Each displays unique features and characteristics. Here are some key aspects of these beetles:
- Soldier beetles have soft, elongated bodies, typically measuring 5-15mm in length.
- Their color ranges from yellow, brown, red, or black, with some having black markings on their bodies.
Common soldier beetles in North America and Europe include the hogweed bonking beetle and the goldenrod soldier beetle. In Australia, the common red and the margined soldier beetles dominate the landscapes.
These beetles exhibit specific behaviors. Here, we discuss a few of them:
- Adult soldier beetles feed on nectar, pollen, and aphids, making them natural pest controllers.
- They are active during the day and can be spotted on flowers or foliage.
- Soldier beetles are usually harmless to humans and do not sting or bite.
To wrap up, here’s a comparison table of two common soldier beetle species:
|Attributes||Hogweed Bonking Beetle||Goldenrod Soldier Beetle|
|Length||7-12 mm||13-14 mm|
|Color||Black with red markings||Yellow with black markings|
|Primary habitat||European gardens||North American meadows|
Now that you know a bit about soldier beetles, next time you spot these friendly insects, you can appreciate their role in maintaining a healthy ecosystem.
Soldier beetles display a variety of colors, which range from yellow to red with brown or black wings or trim. Their heads can also be black, as well as portions of their legs.
Size and Appearance
These insects are elongate and slender, measuring about 1/2 inch in length. Their antennae, which are threadlike and 11-segmented, are commonly held forward of the body. Soldier beetles have wing covers referred to as elytra that can have a smooth to velvety appearance.
Some interesting comparative features are:
|Body length||~1/2 inch|
|Head color||Black or dark-colored|
|Legs color||Black or dark-colored, with spots|
|Wing covers||Smooth to velvety, colored|
A few unique features of soldier beetles include:
- A black patch behind the head and an oval, black spot on each wing cover.
- Wing covers do not completely cover the body, which leaves the abdominal segments exposed.
- Their heads are clearly visible and they have chewing mouthparts.
By learning about the physical characteristics of soldier beetles, like their color mixture, size, appearance, and unique features, you can more easily identify them in your garden or out in nature.
Soldier beetles can be found in various locations across the world, with a significant presence in North America and Europe.
In the US, the Goldenrod Soldier Beetle is quite common, particularly in the Midwest. They are often spotted on goldenrod flowers, roses, and other plants.
North America is home to the Pennsylvania Leatherwing, which is the most common soldier beetle in this region. They can be found in large numbers in gardens and meadows.
Europe also has its fair share of soldier beetles. They thrive in various habitats, including grasslands, forests, and gardens.
Here are some key features of soldier beetles:
- Soft wing covers
- Elongated bodies
- Brightly colored
- Chewing mouthparts
These beetles play a vital role as natural predators, helping control garden pests. Here are the pros and cons of soldier beetles in your garden:
- Natural pest control
- Attracted to diverse plant species
- Possible accidental invaders
Remember, soldier beetles are your friends in the garden, so take care of them and appreciate their hard work!
Habitat and Behavior
Soldier beetles thrive in warmer seasons, particularly spring and summer. During these periods, you can notice them in gardens, meadows, and yards where flowers are abundant. In winter, they are less active and might be hiding in the soil or leaf litter to survive the cold.
For example, the Goldenrod Soldier Beetle is commonly found on goldenrod flowers during the warm season.
Soldier beetles favor various types of habitats, such as:
- Flowering fields
- Home yards
These insects typically prefer habitats with an abundance of flowers, as they feed on nectar and pollen. Additionally, they require soil or leaf litter to lay their eggs.
During daylight hours, soldier beetles actively search for food and mates. They primarily feed on:
- Flower nectar
- Other small insects
Here are some of the daily activities of soldier beetles:
- Crawling on flowers or leaves
- Flying from one plant to another
- Defending their territory from rivals
- Mating in gardens or meadows
In summary, soldier beetles are essential members of your garden or yard ecosystem. They are more active during warmer seasons, like spring and summer, and thrive in environments rich in flowers, soil, and leaf litter. Knowing their habitat and behavior can help you appreciate the beneficial role they play in controlling pests and maintaining the balance of biodiversity.
Life Cycle of Soldier Beetles
During the egg stage, female soldier beetles lay their small, oval-shaped eggs in concealed places like soil, leaf litter, or under bark. These eggs usually hatch within a week or two, depending on environmental conditions.
Upon hatching, the larvae emerge and begin their quest for food. They are carnivorous and actively hunt for prey like small insects and insect eggs, keeping your garden pest-free. During this stage, the larva undergoes a series of molts as it grows bigger, shedding its old exoskeleton to make room for its expanding body.
As the soldier beetle larva reaches its maximum size, it enters the pupa stage of metamorphosis. Encased in a protective cocoon, the larva transforms into an adult soldier beetle. This pupation process typically takes a couple of weeks.
Once the metamorphosis is complete, the adult soldier beetle emerges from its pupal case. In this stage, both males and females actively search for mates to continue the life cycle. Adult soldier beetles feed on nectar, pollen, and small insects, and they play a vital role in controlling garden pests. After mating, the adult beetles will live for a few more weeks before dying.
- Egg Stage: Female lays small, oval-shaped eggs
- Larvae Stage: Carnivorous larva grows and molts
- Pupa Stage: Transformation in a protective cocoon
- Adult Stage: Mating and pest control
Diet and Predation
What Do They Eat?
Soldier beetles feed on various types of insects, mainly focusing on soft-bodied insects such as aphids and caterpillars. In addition, they enjoy consuming insect eggs, protecting your plants from future pests. The adult soldier beetles are attracted to flower gardens because they consume nectar and pollen as part of their diet. Some examples of their food sources include:
- Nectar from flowers
- Pollen from plants
- Insect eggs
This versatile diet makes soldier beetles valuable allies in maintaining the health and balance of your garden.
Who Are Their Predators?
Despite their beneficial role in controlling pests, soldier beetles also face predatory threats. Common predators of these beetles include:
- Smaller mammals
These predators find soldier beetles to be an easy meal due to their small size and relatively slow movement. However, the presence of predators contributes to maintaining the balance within your garden’s ecosystem.
To sum up, soldier beetles play a crucial role in pest control in gardens, feeding on soft-bodied insects such as aphids, caterpillars, and insect eggs. They also enjoy consuming nectar and pollen from flowers. Their predators include birds, spiders, lizards, frogs, and other small mammals. Keeping these facts in mind, you can appreciate the importance of soldier beetles and the delicate balance in your garden’s ecosystem.
Importance of Soldier Beetles
Role in Pollination
Soldier beetles play a crucial role in pollination. These beneficial insects are often found on flowers, where they feed on nectar and pollen. While doing so, they facilitate the transfer of pollen from one flower to another, aiding in the reproduction process of plants. For example, the Goldenrod Soldier Beetle is commonly seen on goldenrod flowers, and their presence enhances the plant’s chances of successful pollination.
Use in Pest Control
Soldier beetles are also valuable allies in controlling garden pests. As predators, they prey on various soft-bodied insects and their eggs, helping to keep pest populations in check. Here are some common garden pests that soldier beetles target:
- Cucumber beetles
- Spider mites
- Various caterpillars
- Grasshopper eggs
- Beetle larvae
Because they target these pests, soldier beetles can reduce the need for chemical pesticides in your garden. They are considered beneficial insects and contribute to a healthy and balanced ecosystem.
By understanding the importance of soldier beetles in pollination and pest control, you can appreciate their role in maintaining a thriving garden environment. By encouraging their presence in your garden, you’ll be supporting a healthy ecosystem and promoting the growth and reproduction of your plants.
Interactions with Humans
Are They Harmful?
Soldier beetles are generally harmless to humans. They do not have the ability to sting, and their bites are rare and usually painless. Although their presence around your home might be a bit of a nuisance, they are not known to cause any significant damage to your property.
Attraction to Homes
At times, soldier beetles may be attracted to your homes, primarily due to their search for prey, such as aphids and other soft-bodied insects. They might also be drawn to sources of light around your home.
How to Discourage Them
To discourage soldier beetles from entering your home or becoming a nuisance, you can consider the following steps:
- Seal any gaps and crevices around your home using caulk to prevent easy access for the beetles
- Reduce the abundance of their prey around your home by managing aphids and other soft-bodied insects
- Minimize the use of outdoor lighting at night or switch to yellow “bug” lights, which are less attractive to insects
Remember, while soldier beetles may be a slight inconvenience, they are important natural predators that can help control other pests in your garden and yard.
Interesting Facts about Soldier Beetles
Soldier beetles, often seen on flowers, are fascinating insects with unique features. Here are some interesting facts about them:
- These beetles have wings that are more leathery than shell-like, and their wing covers don’t completely cover the body, leaving some abdominal segments exposed (source).
- Soldier beetles vary in color; some are brown or black, while others are red or orange with dark brown or black markings (source).
- They are good at controlling garden pests as they are predators of insects like aphids and caterpillars. Additionally, they are pollinators (source).
One common species you might encounter is the goldenrod soldier beetle, which is almost 3/4 inch long and often found on goldenrod, roses, and other flowers. It has an orange body with two prominent brown-black spots on the elytra (source).
Soldier beetles might remind you of lightning bugs or fireflies due to their similar body shape, but they don’t produce light. Compared to wasps, soldier beetles have a more flattened and elongated form, and they don’t make any distinct sound or scent.
While observing them, you may spot females and males pairing up during the mating process. These beetles don’t pose any threat to humans or plants, so you can admire them up close without worry.
In summary, soldier beetles are beneficial insects that play a key role in pest control and pollination. By understanding their interesting features, you can appreciate their presence in your garden.

Letter 1 – Brown Leatherwing
Brown Leatherwing Beetle
Location: Northern California
May 3, 2011 3:03 am
I have noticed a different kind of bug hanging around my house and was very curious on what kind of bug it was. I took a picture of this bug and started researching the bug. I located the identification of the bug on your web page; Brown Leatherwing Beetle. I would like to know what this beetle likes to eat and if it will harm or damage anything? I would also like to know where the beetle likes to lay it’s eggs?
The Brown Leatherwing, Pacificanthia consors, is a common California species, and this year they seem to be more numerous. They are also attracted to lights, so they are frequently encountered by humans, however, our typical sources, BugGuide and the Insects of the Los Angeles Basin, a book by Charles Hogue, do not provide information on the life cycle, though both agree that this is not a harmful species. We did locate some wonderful information on the Pacific Horticulture website. Frédérique Lavoipierre, Garden Ecologist writes: “In his detailed and fascinating 1964 book, Beneficial Insects, Lester Swan comments on several beneficial species of soldier beetles and their associated prey, then notes that, unfortunately, they have not been studied extensively. Not much has changed in the ensuing four decades. ‘Oh, those! I have them in my garden, but I didn’t know they were beneficial,’ is the now familiar response when I point them out to garden visitors. Yet soldier beetles surely warrant the same recognition given to lady beetles and lacewings. In suitable habitat, they are a reliable and valuable ally. It is far easier to supply ideal living conditions for soldier beetles in gardens than in agricultural fields. This lack of potential for commercial use may help explain why soldier beetles have been so little studied, despite a voracious appetite for aphids, caterpillars, grasshopper eggs, mites, and other small pests. They are even reputed to attack cucumber beetles—reason enough for gardeners to agree that soldier beetles deserve further study!” We are thoroughly charmed by the Pacific Horticulture website, and we fear for the longevity of information that is provided on the internet because websites come and go. At the risk of getting dinged for copyright infringement, we feel compelled to directly quote more of the information provided by Frédérique Lavoipierre including this information on mating rituals: “The female soldier beetle sometimes attracts hordes of males with the pheromones she emits, but generally only one male is successful. Most beetles don’t engage in elaborate courtship behaviors, but some soldier beetle males may ‘nibble’ females. Considering that soldier beetles usually only mate once, when there are a lot of these beetles in the garden, there seems to be a lot of ‘nibbling’ taking place! Since each female has a huge supply of eggs, building up good garden populations need not take a long time. The nocturnal larvae hatch in spring and are found in damp areas beneath rocks, in leaf litter, or under bark, where they prey on insects and other small organisms. A year or more after hatching, the larvae pupate and emerge as adults.
Soldier beetles have a varied diet, feeding on aphids and other homopterans, grasshopper eggs, caterpillars, root maggots and other soft-bodied insects. Many genera of soldier beetles, such as Cantharis, Podabrus, and Pacificanthia, are primarily carnivorous in both the larval and adult stage, but a few are minor pests in the larval stage, feeding on roots. Larvae primarily eat eggs and larvae of beetles, moths, grasshoppers, and other insects. Adults are frequently found on a variety of flowers, where they feed on pollen and nectar in addition to insect prey such as aphids and mealybugs. Because they are generalist predators, soldier beetles may also eat beneficial insects, such as lacewing larvae and aphids that have been parasitized by wasps.” Finally, the Pacific Horticulture website provides this sage gardening wisdom: “Encouraging a resident population of soldier beetles is easy in gardens. Choose suitable flowers to bloom over a long season. Any habitat garden must include a water source; soldier beetles are particularly known to frequent moist habitats. It is important to the life cycle of soldier beetles (and many other beneficial organisms) that they have undisturbed, mulched soil in which to pupate, so include permanent perennial plantings in gardens. A fragile and important community thrives at the interface between soil and organic matter. In permanent plantings, avoid raking and add organic material to the surface of the beds as needed to keep the soil in good fertility.”
Letter 2 – Goldenrod Soldier Beetles Mating
August 31, 2009
I thought you might like a photo of some margined leatherwing beetles in the mating act.
near Omaha NE
Thanks for sending us your Bug Love image, but we don’t believe these are Margined Leatherwings. That species, according to BugGuide, is “Very similar to C. pennsylvanicus, but pronotum has wide dark band, instead of an irregular dark spot. Elytra of C. marginatus often more extensively dark than pennsylvanicus. C. marginatus is also somewhat smaller and is active earlier in summer than C. pennsylvanicus.“ In our opinion, your photo depicts mating Goldenrod Soldier Beetles or Pennsylvania Leatherwings, Chauliognathus pensylvanicus. Compare your image to the images posted on BugGuide.

Your letter to the bugman: Hi Bugman,
I need your help identifying this bug. I have no where else to turn and I have searched for hours for an answer.
Thank you for your service
How you want your letter signed: A bug wonderer
Dear Bug Wonderer,
This is a Soldier Beetle in the family Cantharidae, and based on this BugGuide image, we believe it is Cantharis rufa. According to BugGuide: “native to, and widespread across the Palaearctic, adventive in NA (e. Canada & ne. US: NF-ON to MA-NY).” According to the family page on BugGuide: “Adults eat nectar, pollen, other insects; larvae are fluid-feeding predators, feed on insect eggs and larvae,” hence they are beneficial.

Our three best guesses for your Beetle’s family are Soldier Beetle family Cantharidae, Net-Winged Beetle family Lycidae or Firefly Beetle family Lampyridae. Interestingly, all three families are in the same superfamily Elateroidea. It looks similar to the Red Soldier Beetle, Rhagonycha fulva, a species native to Eurasia, introduced into North America and pictured on Focusing on Wildlife.
Dear sir….thank you so much….i also found similarity with red soldier beetle but was confused as i read that its not native to India….then how come its founs here ao asked for identification..thank you again

A longhorn beetle?
April 23, 2010
Hello. This cute little guy flew into my house at night. The “fern” like legs are very attractive. it’s about half an inch long with fuzzy brownish grey wings, and a red head. I wonder if it’s a type of longhorn beetle? thanks in advance for your help!
We have been seeing these Brown Leatherwings, Pacificanthia consors, formerly Cantharis consors, on our own front porch windows where they are attracted to the porch light. Though the antennae of the Brown Leatherwing are long, they are not Longhorned Beetles, but rather, Soldier Beetles in the family Cantharidae.

OK Ive been going nuts on Google trying to find these guys , i made a little garden around a sycamore tree and these things are EVERYWHERE hundreds of them and i cant seem to ID him would be appreciate it , Sorry about the photo quality hard to take a pic of em , they seem to ”sleep” during the day and if you wake them they run off and fly they’re about an inch long total wish i could describe them better , Thanks.
Though your photo is quite blurry, we are relatively certain you have Brown Leatherwings, Pacificanthia consors, though that common name is attributed to Charles Hogue in his awesome book, Insects of the Los Angeles Basis, and the common name is not recognized on BugGuide. According to Hogue, Brown Leatherwings feed on small insects they find among leaf litter, so they will not damage you nor your property.
Thanks for the quick response , yep thats them alright its very much appreciated thank you for your time.

A bunch of these guys just showed up around our porch light. They don’t do much. We never noticed them here before.
Greetings from neighboring Mt Washington. Thank you so much for supplying this image of a Brown Leatherwing, 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. Here is what Charles Hogue wrote 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.” We will try to flesh out this posting a bit more if we are able to locate any specific information on the Brown Leatherwing. While this is probably a more appropriate candidate for our May Bug of the Month, we couldn’t resist posting a photo of an unidentified Click Beetle that we also found at our Mt Washington location.

Please help! We’ve noticed a large amount of these flying insects on a nightly basis since it has warmed up in the area. In 13 years, I’ve never seen these bugs before & they’re highly attracted to the light. I’m not a fan of any bugs & besides being gross, is there anything I need to know about these creepy crawlies?
I’d appreciate your help!!
The Brown Leatherwing is a harmless, beneficial species. They seem to be appearing in prodigious numbers across the state of California this year, which prompted us to declare them the Bug of the Month for May, a feature posting that you somehow missed when you visited our website where it is prominently featured on our homepage. Brown Leatherwings are attracted to lights, so keeping the porch light turned off will keep them from coming to your home.
Thank you so much! We have been keeping all outside lights off & it seems to help! Not sure how I missed the Bug of the Month, but I will check it out again!

Thanks for sending in this photo. We have been neglecting taking a photo of the Brown Leatherwings that are attracted to our own porch light each spring. The Brown Leatherwing, Pacificanthia consors, is a west coast species that is considered beneficial. 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 prey on other insects.” They pose no danger to you or your family. Brown Leatherwings appear each spring and remain for approximately six weeks.

In an effort to educate our readership and to promote tolerance of beneficial insects that pose no threat to humans, we created an Unnecessary Carnage tag for letters like yours. This Brown Leatherwing appears to have been squashed in a paper towel. The Brown Leatherwing, Pacificanthia consors and formerly Cantharis consors, is a species of Soldier Beetle and adults are frequently attracted to porch lights in southern California. Keeping the porch light off at night will conserve energy as well as eliminate the number of Brown Leatherwings that enter your home. Soldier Beetles are predators, and the Brown Leatherwing feeds upon other insects.

Dear Curious Dad,
Normally as the most commonly liked posting on our site states, What’s That Bug? will not do your Child’s Homework, but we liked the earnestness of your request, so we will point you in the right direction, and let you do the research. This is a Brown Leatherwing, Pacificanthia consors, and it is a common Southern California sighting in May because this Soldier Beetle is often attracted to lights. We are quite fond of this predatory species since we are located in Southern California in the Los Angeles neighborhood of Mount Washington, so there are numerous postings on our site.

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.

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.

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!

Because this Soldier Beetle in the family Cantharidae is either newly metamorphosed, or it has been injured or it is just deformed, it will be difficult to identify in most field guides. We believe it is Atalantycha bilineata based on this BugGuide image. According to BugGuide, it is called a Two Lined Leatherwing and its habitat is “hardwood and pine forests; adults like the flowers of Red Haw, Viburnum rufidulum.“
Thank you so much!!! My love of bugs is only about 10 years old. I used to fear them but then slowly began to find them incredibly interesting which eventually turned into finding them wonderful.
I also wanted to mention that I was just on your firefly page and clicked an ad for Nume curling irons. The ad on the page had a promo code, shop24 which was supposed to yield a significant discount. When I went to check out it said the code had expired. I’m not really looking for you to resolve this issue :-), I just thought you guys should know since they advertise on your site that there’s a small possibility they might not be on the up and up. Of course, this could’ve simply been a clerical error. Just an FYI.
Anyway, thank you so much again. You have absolutely made my day! 🙂

For Bug Love
These are mating Soldier Beetles, and there is not a high enough resolution in your image to be certain of the species. We located several similar looking species on Nature Spot, and regarding the species Cantharis cryptica, Nature Spot indicates: “7 to 8.5 mm. An orange/brown beetle with black rings above the ‘knees’ and all-yellow palps. There are several similar species and precise identification may need detailed examination.” Another possible species is Cantharis rufa, and Nature Spot indicates: “Length 9 – 11 mm. This soldier beetle is largely all orange but sometimes there is a black mark on the pronotum which is quite square looking and doesn’t reach to the front border (extending just over half way). The legs may be be pale or dark but with contrasting ‘knees’ in both cases. Similar Species: This species is larger than the similar Cantharis cryptica and C. pallida – both of which are 7-8mm in length. Rhagonycha translucida lacks the blacks knees and has a pronotum that narrows towards the head.” Of the similar looking Cantharis pallida, Nature Spot indicates: “They are frequent visitors to thistles and umbelliferous flowers, where they probably prey on other flower-feeding insects.” That is a thistle in your image. Finally, we could not rule out the larger Common Red Soldier Beetle, Rhagonycha fulva, and Nature Spot states: “A very common beetle throughout most of Britain.” After all that, we hope a family identification will suffice.

This little red guy loves to hover around my little lime hydrangeas. They can fly, albeit slowly, even next to the bumbles that devour my lavender that lives next to my hydrandea. I would love to know what they are and if/how they are beneficial to my garden.
These are Soldier Beetles in the family Cantharidae, and we believe we have correctly identified them as Rhagonycha fulva thanks to this BugGuide image which shows the black tipped wings. According to BugGuide: “adults often found on flowerheads of herbaceous plants during the day” where “adults feed on small insects that visit flowers; larvae feed on snails, slugs, and ground-dwelling insects.” BugGuide also notes it is “native to Eurasia; introduced to North America some time ago” and “well-established in British Columbia and Quebec.” Despite not being a native species, all indications are that this is a beneficial insect in your garden. Finally, we are amused that BugGuide notes that its common name is Hogweed Bonking Beetle.

The Common Red Soldier Beetle, Rhagonycha fulva, is, according to BugGuide: “well-established in British Columbia and Quebec [Pat Bouchard]; recently recorded in Ontario from BugGuide photos … native to Eurasia; introduced to North America some time ago.” BugGuide also indicates: “adults feed on small insects that visit flowers larvae feed on snails, slugs, and ground-dwelling insects” and especially interesting, that it is also called Hogweed Bonking Beetle. ” The Garden Safari website indicates it is because “The Hogweed Bonking Beetle (Rhagonycha fulva) is often seen in copula on plants and flowers.”
Letter 19 – Leatherwing
You have a great website! I found some similar looking bugs, but not exactly. I’m hoping you can ID the bugs in these pictures. Thanks for your help! The bugs in PICT0268 and PICT0126 come in the house in large numbers through small cracks at the side of the screen. They seem to arrive in the fall. The majority move to windows on the side of the house with the sun. The bug in PICT0126 is a brownish gray with yellow markings (the coloring is a bit off). PICT0006 and 0008 are different sides of the same bug. They don’t come in the house. They arrive in early spring and have voracious appetites for aphids on rose bushes leaving black oilish smears on the leaves.
Your aphid eater is a Leatherwing, ond of the Soldier Beetles. It resembles Podabrus pruinosus pictured on BugGuide. BugGuide also indicates that many species eat aphids. We have neglected photographing our own species that has been attracted to the porch light for the past month.

Your letter to the bugman: Growing corn for years and this had never been an issue. Two types of bugs have destroyed all my corn in my garden.
How you want your letter signed: Emilia
Not every insect found on your corn plants is injurious to your crop. The image with the smaller beetles does not have enough detail for us to provide an identification, but the beetles in two of your images are Margined Leatherwings, Chauliognathus marginatus, and according to BugGuide: “Adult feeds on pollen and nectar; also predatory. Larva is predatory, known to attack corn earworm and corn borer.” This is actually a beneficial insect on your corn plants. The damage that is visible to the ears of corn in the images you provided does not look to us like it was caused by insects. We suspect rodents or some other larger creature is eating your corn at night, and that the Margined Leatherwings were accused of the damage through circumstantial evidence by merely being present at the scene of the crime.

These mating Soldier Beetles are living up to their name Hogweed Bonking Beetles. They are an introduced species from Eurasia and they are predators. The dark tips of the wings are an identifying feature.

Hi again Lori,
You submitted so many excellent photos, we wanted to post
another. These are mating Leatherwings, a type of Soldier
Beetle. We believe it is Chauliognathus omissus which can
be found on BugGuide
and is native to Arizona and vicinity. It looks very similar
to an eastern species, the Pennsylvania Leatherwing or Goldenrod
Soldier Beetle. Your photo doesn’t truly depict a “foursome”
since they are two pairs on different flower heads. Since
beetles and other insects don’t generally have a bedroom in
which to retreat for privacy, they have no choice but to procreate
in the open air. While such behavior might be unseemly in
humans, it is completely natural for insects. It is sad that
procreating in the great outdoors is taboo behavior for “civilized”
humans who are being denied the right to truly commune with nature lest they risk incarceration.

Thank you for your descriptive letter and wonderful images including the mating behavior of the Margined Leatherwings, Chauliognathus marginatus. According to BugGuide: “Very similar to C. pennsylvanicus, but pronotum has wide dark band, instead of an irregular dark spot. Elytra of C. marginatus often more extensively dark than pennsylvanicus. C. marginatus is also somewhat smaller and is active earlier in summer than C. pennsylvanicus.” Chauliognathus pennsylvanicus is known as the Goldenrod Soldier Beetle, and it makes its appearance in September when the goldenrod is blooming. The adults feed on nectar and pollen, and possibly aphids, but the larvae are considered beneficial predators. Your observation that birds don’t eat them is interesting, and it may be related to a foul taste. Interesting, according to BugGuide regarding the family name Chntharidae: “The compound cantharidin is named for this group of beetles, presumably, but was actually isolated from blister beetles, Meloidae–at that time presumably the family was included with the Cantharidae.” We are setting your wonderful letter and photographs to post live to our website between June 15 and June 22 when we will be visiting mom and working in her garden. That way our readership can get daily updates while we are out of the office.

Before I post these pics for my friends to view, I was hoping to get some insight to see if I am right on the identification of these beetles. I took this picture a few weeks ago on a fishing trip and have since identified these two beetles as Pennsylvania Leatherwings (Chauliognathus pennsylvanicus), please correct me if I am wrong. But the other beetle in the second photo has me stumped. At first appearance to someone who is uninterested, it would appear the same. But I have been searching to identify this other beetle and have not done so yet. I was wondering if you could help me out with its identification. It was on the daisy right next to the daisy that the Pennsylvania Leatherwings were on. Thanks so much for your time and everything that you do…you have an awesome website!
Justin Stair of Nigh Wolf Lofts & Aquatic Wilds
Your identification is so close, but no cigar. It is a few months early in the season for Pennsylvania Leatherwings, also known as Goldenrod Soldier Beetles. They are active from late August to October, when the goldenrod is in bloom. All of your beetles are the closely related Margined Leatherwings, Chauliognathus marginatus. According to BugGuide, the Margined Leatherwing is: “Very similar to C. pennsylvanicus, but pronotum has wide dark band, instead of an irregular dark spot. Elytra of C. marginatus often more extensively dark than pennsylvanicus. C. marginatus is also somewhat smaller and is active earlier in summer than C. pennsylvanicus.“

Thanks for the positive words about our new site format. Your mating Pennsylvania Leatherwings, AKA Goldenrod Soldier Beetles, is quite a nice addition to our archives
Update: 29 September 2008
It is time for us to select a Bug of the Month, and we almost chose the Locust Borer, but that was our Bug of the Month for October 2007. Pennsylvania Leatherwings, Chauliognathus pensylvanicus, are a good choice, because like the Locust Borer, they are associated with that common wildflower Goldenrod. When the Goldenrod blooms in the fall, there is an entire ecosystem that depends upon it for survival. We have fond memories of running through the fields in Ohio when the Goldenrod was in bloom, after school started but before the cold winter weather arrived. Preying Mantids were everywhere, as were a variety of Orb Weaving Spiders. The Monarch Butterflies were migrating, and the last Swallowtails and Fritillaries and Painted Ladies came to the blossoms for nectar. Wasps and Bees and the beetles that mimic them like the Locust Borer were everywhere on the flowers. Grasshoppers were hopping and flying about. The Pennsylvania Leatherwings were also quite common, but their smaller size kept them from being the dramatic stars in the drama of eat or be eaten that was happening around them..

Hi. I love your site. Hopefully you can help me identify this beetle found on a flower in eastern ontario.
Despite being called the Pennsylvania Leather-Wing, the range of Chauliognathus pennsylvanicus extends beyond the Keystone state. Adults eat pollen and nectar and are often found on goldenrod and in meadows, fields and gardens. Larvae prey on grasshoppereggs, small caterpillars and beetles. The are great biological controls for Corn Earworms.

Dear unintentional entomologist,
The Pennsylvania Leatherwing or Goldenrod Soldier Beetle is frequently associated with goldenrod, a common autumn bloom, and we are surprised that your photo is the first submission this year. Typically, we begin to have identification requests for Pennsylvania Leatherwings beginning in September.
Actually, I took this picture on September 3, but I took a couple of hour’s worth of photos that day including ducks, egrets and blue herons which were having great success wading and fishing in a shallow section of a rain-depleted Fox River. Consequently, I did not get around to processing the macro-lens photos from along the river bank until October 27th. There were some pictures of goldenrod in the group, but none had this beetle in it.
I guess I still would have been your first submission this year, but at least it would have been within your expected time frame.

I photographed this guy in Costa Rica, at about 1000 m elevation. Can you help me to identify it? Thank you!
Depending upon how specific you would like our answer to be, we may or may not have an answer for you. This is a Beetle, a member of the insect order Coleoptera, the largest group of insects in the world. Beyond that, we cannot be certain. It appears that this beetle has deformed elytra, and we are not certain if that is a characteristic of this particular species, or if this is a deformed individual that did not develop correctly. We are favoring the latter possibility, which might greatly complicate its identification if it does not resemble other members of its species due to the deformity. It also appears to be a soft bodied beetle, without the hard elytra or wing covers that is a characteristic of most beetles. We are guessing this individual is likely in the superfamily Elateroidea. It resembles the Net-Winged Beetles in the family Lycidae and you can compare your specimen to this Golden Net-Wing pictured on BugGuide. as an example of how a “typical” family member looks. The light tip on the abdomen might suggest bioluminescence and could mean your beetle is a Firefly in the family Lampyridae. Your beetle also shares some characteristics of the Soldier Beetles in the family Cantharidae. There is much more diversity in the tropics and there are also many poorly documented species as well as undocumented species in the tropics. Our main source of information is the internet, and many organisms are poorly represented on the internet. We tried a web search of “red beetle Costa Rica” and most of the images produced by google were not even beetles. Perhaps one of our readers will be able to provide a more specific answer for you.
Eric Eaton provides an identification
Yes, it is a soldier beetle, family Cantharidae.
Do you agree it is either deformed or hasn’t had the wings fully expand after metamorphosis?
Yes, probably a bad molt.

This is my second asking, as I did not receive an answer to my first request, and although I’ve quite a lot of looking at BugGuide and searching with google, I can’t figure out what this is. I’ve become concerned that it may be some kind of termite.
We found it on the carpet in our apartment in eastern Pennsylvania.
We apologize for the delay. Our tiny staff tries to respond to as many requests as possible, but we can never fully fulfill the demands of our readership. This is NOT a termite. It is the larval form of some insect, most likely a Beetle, but we need to do additional research. Hopefully we will eventually be able to provide an identification since larvae are often notoriously difficult to identify to the species level.
Thanks for getting back to me. I’m glad to hear it isn’t a termite.

Thanks to a comment from one of our readers, we are confident this is a Soldier Beetle Larva as it looks nearly identical to this photo posted to BugGuide.

Hello bugman, first and foremost I would like to thank you for helping me identify the species, and for the information I have already learned so much from!
There are several brown Leatherwing beetles on my porch tonight.
I know that this is a common time of year for this species, and I know they are attracted to light! I also learned from your site they are very beneficial. Thank you for that!
I was initially curious because all three specimen were on there backs, they appeared to be writhing. I would like to know what’s happening to them. Originally I thought it may be a female hatching her eggs, but after longer examination and further education from Pacific Horticulture, I realized the beetle had yet to produce any eggs (with microscopic examinatio)Also, they’re movement started to slow, they did not die however(at least as of now) and when I tried to flip the beetle over(making sure they weren’t stuck) they put themselves again on their backs, and continued the decreasing writhing!
Do you think something may be wrong? Is this the end of their adult life span(1 year)?
The only other theory I have is that it may have been a female releasing her pheromones?
I know the information is limited, but any additional information you may be able to offer would be much appreciated! I hate to see any living creature suffer, if this is the unfortunate reality!
Thank you again for all the education I gained from your site, including identifying the insect.

Thank you for your kind compliments. Alas, we don’t know what is troubling your Brown Leatherwings, but they are not acting normally. They seem to be dying. Perhaps they were exposed to toxins nearby. You might have a neighbor who is not as sensitive to the environment as you are. Adults do not live an entire year. Their lifespan is probably closer to six weeks, but since this is the start of the season that we generally see them, we don’t think they are dying of old age.

These are not Bark Beetles. They are True Bugs and we located a matching image on Insects of Spain, but it is not identified. Continued research led us to Honey Guide where we found images identified as Ground Bugs, Spilostethus pandurus. That scientific name led us to Fauna and Funghi of Malta and the common name Soldier Bug and the information: “A common insect often found solitary on wild plants or on the ground in vegetated areas. It is 12-15mm long and easily spotted due to its conspicuous red/black colour pattern. Despite it can be easily detected and caught by predators, it defends itself from them by secreting pungent odours and have a very repulsive taste, hence the predator will not eat another specimen of this species. It have pecial needle-like mandibles by which it pierce vegetative parts or other insects to feed on.” iNaturalist verified the common name Soldier Bug as well as numerous sightings in Spain.

Your insect is both a Stink Bug and a Spined Soldier Bug. Stink Bug is a general name for members of the family Pentatomidae.

While most Stink Bugs feed on plants using their sucking mouthparts, and many Stink Bugs are considered agricultural pests that would not be welcome in the garden, the Spined Soldier Bugs are predators, and though they may also prey on beneficial insects, their presence would generally be welcomed in the garden.

I thought this was a Spined Soldier Bug. The red patch on its back is not in any information I have found.
The angle of view of your photo makes it difficult to ascertain for certain that this is a Spined Soldier Bug, Podisus maculiventris, but we believe that you are probably correct because of the spines on the pronotum at the widest point of the body. A photo posted to BugGuide shows some reddish markings on the individual as well as reddish legs. Perhaps there are some latent genes that may eventually result in a population with red markings for this beneficial Predatory Stink Bug.

Been doing extensive research and can’t identify this beetle. I’m in Oak Park, Illinois and hoping it’s not destructive to the garden
This is not a Beetle, which might explain the difficulty you have had identifying this immature Stink Bug. We believe it is a predatory Spined Soldier Bug nymph, Podisus maculiventris, based on this BugGuide image. According to BugGuide it is: “available commercially as biocontrol agent against a wide array of agriculturally significant pests” and it feeds on a “Wide variety of insects; known to eat Mexican bean beetles, European corn borers, diamondback moths, corn earworms, beet armyworms, fall armyworms, cabbage loopers, imported cabbageworms, Colorado potato beetles, velvetbean caterpillars and flea beetles.”
Thanks so much for solving the mystery AND your quick response! I’m happy to hear it’s not destructive to my plants.
