Do Wheel Bugs Bite? Uncovering the Truth about These Insects

folder_openHemiptera, Insecta
comment26 Comments

Wheel bugs are fascinating insects known for their unique appearance and beneficial role in the ecosystem. These large, distinctive-looking bugs get their name from the cog-like toothed wheel on their thorax, a structure unique to their species in Illinois and the U.S. source. They play a crucial role in controlling pest populations, as they are predators that feed on other insects.

While wheel bugs are considered beneficial to have around, they are also known for their painful bite. It’s crucial to handle these bugs with caution, as their bites can be more severe than a bee sting source. In fact, a wheel bug bite has been described as much more powerful than a hornet or wasp sting, taking about 10 days to heal and leaving a small scar source.

Understanding Wheel Bugs

Appearance

Wheel bugs (Arilus cristatus) are distinctive insects known for their unique, cog-like structure on their thorax. They can be quite large, measuring between 1 to 1-1/2 inches long, with a light gray to grayish-brown color. The most notable feature is the “wheel,” which has 8-12 teeth or tubercles 1. These insects have thin, rusty brown antennae and front legs adapted for capturing prey 2.

Distribution and Habitat

These insects are widely distributed and can be found throughout the United States 3. They are commonly found in various habitats, such as forests, gardens, and fields, where they prey on other insects, including ants, beetles, and aphids 4.

Lifecycle

The lifecycle of a wheel bug consists of several stages, from eggs to nymphs, and finally, adults. Female wheel bugs lay clusters of eggs, which eventually hatch and release nymphs 5.

Nymphs undergo several instar stages, progressively growing larger and developing their characteristic “wheel.” They change color during this process, initially appearing red and transitioning to a cryptic gray 6.

Wheel Bug Bites

Why Wheel Bugs Bite

Wheel bugs, or Arilus cristatus, are a type of assassin bug that prey on pest insects to feed themselves. Though helpful for controlling pests, they tend to bite humans when they feel threatened or are mishandled. A wheel bug bite can be more painful than a hornet or wasp sting. It’s important to treat their bites with caution, especially when dealing with children.

Symptoms

Some common symptoms of a wheel bug bite include:

  • Painful sensation at the site of the bite
  • Redness and swelling
  • Itching and irritation
  • Hives or welts

In some cases, individuals who are allergic to insect bites and stings might experience anaphylactic shock. This could be a life-threatening situation and requires immediate medical attention.

Treatment

When bitten by a wheel bug, consider the following treatment options:

  • Wash the wound: Clean the area with soap and water to reduce the risk of infection.
  • Apply a cold compress: This helps to minimize swelling and pain.
  • Use a topical cream: Apply a hydrocortisone or antihistamine cream to alleviate itching and inflammation.

If the symptoms worsen or an allergic reaction occurs, seek immediate medical help.

An overview of wheel bug bites:

Aspect Wheel Bug Bite
Cause Threatened or mishandled wheel bugs
Pain level More painful than a wasp or hornet sting
Symptoms Pain, redness, itching, swelling, hives
Treatment Washing, cold compress, topical cream

Remember to handle wheel bugs carefully to avoid getting bitten, and seek medical help if the symptoms worsen or an allergic reaction occurs.

Wheel Bugs and Your Home

Indoor Infestations

Wheel bugs (Arilus cristatus) are members of the Reduviidae family, known as assassin bugs. They are beneficial insects that prey on other pests like flies. However, these bugs can occasionally venture indoors and infest homes, especially in areas like Florida, where they are more prevalent. Despite being helpful for controlling pests, wheel bugs can deliver a painful bite, making them unwanted visitors in residential spaces.

When found indoors, it’s essential to address wheel bug infestations with caution, as their bites can be more severe than a bee sting. Proper pest control and preventative measures can help reduce the risk of an infestation.

Prevention Measures

To prevent wheel bugs from entering your home, consider implementing the following strategies:

  • Seal Cracks and Gaps: Check for cracks and gaps around doors and windows. Seal them using caulk or weatherstripping to deter these pests from coming in.
  • Install Screens: Ensure all windows and doors have well-fitted screens to keep out wheel bugs and other insects.

The table below gives a brief comparison of two prevention methods:

Method Pros Cons
Sealing gaps Effective in keeping insects out Can be time-consuming
Installing screens Allows airflow while blocking bugs May require professional installation

Addressing wheel bug infestations often requires a balanced approach, as they are beneficial insects. Limiting the use of insecticides and pesticides can help maintain their positive impact on controlling other pests while taking proactive steps to keep them out of your home.

Ecological Role and Benefits

Predatory Behavior

Wheel bugs, also known as assassin bugs, are beneficial insects that serve as predators in the garden. They are known for hunting various arthropods, especially soft-bodied insects such as caterpillars and moths. With their piercing, sucking mouthparts, they easily catch and consume their prey. It’s important to understand their predatory behavior, as this knowledge can assist in utilizing them as beneficial insects for garden pest management.

Examples of wheel bug prey:

  • Caterpillars
  • Moths
  • Soft-bodied insects

Benefits to Gardens

Wheel bugs are valuable predators in gardens due to their appetite for many common pests, such as stink bugs and bees. Specifically, they have been known to prey on the brown marmorated stink bug, which has been an increasingly persistent problem for gardeners. Additionally, these true bugs can help keep populations of unwanted insects in check, promoting an overall healthier environment for your plants.

Key benefits of wheel bugs in gardens:

  • Prey on a variety of pests
  • Help control stink bug populations
  • Support healthy plant growth

Comparison table: Wheel Bugs vs. Brown Marmorated Stink Bugs

Feature Wheel Bugs (Assassin Bug) Brown Marmorated Stink Bugs
Size Gray, 1.0 – 1.25 inches long Brown, 0.5 – 0.6 inches long
Appearance Red and black, with a distinctive cogwheel-like structure on their back Brown, marmorated color pattern, with a shield-shaped body
Harmful to Garden No, they are beneficial predators Yes, they feed on plants and can cause damage
Overwintering Yes, they can overwinter as adults Yes, they can overwinter as adults
Pest Management Role Beneficial predator, helps to control pest populations Pest, can cause plant damage and requires management

By understanding the ecological role and benefits of wheel bugs, gardeners can harness their predatory behavior to maintain a healthy and thriving garden ecosystem. Their presence has positive effects, such as the reduction of stink bug populations and damage to plants. Remember to appreciate the wheel bugs in your garden and the important contributions they make!

Assassin Bug Family and Related Insects

Assassin Bug Family

The Assassin Bug family, also known as Reduviidae, is a group of insects that are primarily predators of other insects. One of the most well-known members of this family is the wheel bug (Arilus cristatus). Wheel bugs are large, distinctive-looking insects with a prominent cog-like toothed wheel on their thorax. These insects are important predators of forest insects and provide valuable pest control services in gardens and yards.

Examples of other insects in the Reduviidae family include:

  • Kissing bugs
  • Masked hunters

Kissing bugs are known for transmitting Chagas disease, which can be harmful to humans. On the other hand, masked hunters prey on household pests like bed bugs and cockroaches.

Other Insects in the Hemiptera Order

The Hemiptera order encompasses a wide variety of insects, including wheel bugs and other assassin bugs. This order is composed of over 80,000 species of insects, with some being wingless while others having wings. Examples of insects within the Hemiptera order are:

  • Aphids
  • Leafhoppers
  • Scale insects
  • Stink bugs

These insects are characterized by their piercing and sucking mouthparts, which allows them to feed on plant sap, other insects, or even vertebrates like birds and reptiles.

Wheel Bug Aphid
Appearance Gray, cog-like wheel on thorax Tiny, pear-shaped body
Feeding Habits Predatory Plant sap
Role in Ecosystem Pest control Plant pests

When dealing with pest insects in the Hemiptera order, using insecticides can be effective. However, it’s important to remember that beneficial insects like wheel bugs and other assassin bugs can also be affected by these treatments. Therefore, it’s crucial to ensure that pest control methods do not harm beneficial insect populations.

Hi,
I took this photo yesterday (10/24/2010) of a large bug in my driveway. This is in SouthWestern Pennsylvania which is under a stink bug assault right now. The funny thing is several others at work have seen this bug just this weekend. One person brought in the same thing but it was entirely black instead of brown colored. We’ve called it the ”stink bug queen” and ”mutant stink bug” but really have no idea. What is this?

Wheel Bug

Dear Eric,
We have gotten so many requests in the past week to identify Wheel Bugs that despite it being chosen Bug of the Month in November 2008, we felt it warranted receiving the title again this year.  The Wheel Bug,
Arilus cristatus, is the largest Assassin Bug in North America.  They are slow moving predators, and though they are capable of biting, we receive very few reports of people being bitten even after handling Wheel Bugs.  Many people describe the Wheel Bug as looking prehistoric or comparing them to dinosaurs, particularly the Stegosaurus.  In the spring, we get numerous identification requests for Wheel Bug hatchlings that look like red and black ants clustered around the remains of the egg mass that has passed the winter attached to a tree branch or fence post.

Letter 2 – Immature Wheel Bug

 

Help with identification, please?
Hi, I just found your site…I can’t stand bugs but this is a great idea! We’ve seen these bugs just in the last year or two here around our home. We live just across the road from the Susquehanna River, in Northeast PA (about 40 miles from the capitol of Harrisburg.) And we live near a chicken farm (with trees between us and the farm.) This photo shows what I believe to be a baby –we call them "red and black bugs". They don’t fly but live in the trees and also collect on the top rail of our fence and on the roof of the kids’ playhouse. They are sometimes found on what we call a "nest" –a kind of dark colored, low profiled honeycomb looking thing attached to the tree bark. Not sure if this is where they live or where they store their food? They grow to be at least an inch long, and if I recall correctly, the red on their tail section becomes less pronounced. They’ve got this strange red tail section that sticks up in the air. They have 3 legs down each side, 2 long antenna, and a hook-like thing at their mouth, which in the first picture is extended outward. They seem to be able to tuck it in and out whenever they want to. When they see you coming, they make evasive maneuvers to get away from you and will not hesitate to jump down to the grass from their perch in order to get away. I have seen one or two eating/carrying bugs. Also, some have a black stripe down the back of their red tail section, and some don’t have that. This particular example has the black stripe. I guess if you could tell me if they’re harmful, bite, sting etc. and of course what they’re called, I would sure appreciate it…also, what we can do to get rid of them? Or just leave them be? Thanks so much, I look forward to your reply.
Marjorie

Hi Marjorie,
What a nice descriptive letter. You hit all the points we like people to tell us regarding the photos they send. This is an immature Wheel Bug. They are predators and very beneficial in gardens and orchards. They eat many harmful insects. On the down side, they can bite painfully, but the bite is not dangerous. Just don’t handle them. Adult Wheel Bugs have wings and can fly. They have a distinctive coglike crest which alludes to the common name.

The most awesome image of a Wheel Bug

Dear Terrified,
Franklin D. Roosevelt said “The only thing we have to fear is fear itself.”  This Wheel Bug is a predatory Assassin Bug and it might bite if provoked, and the bite would likely be painful if it occurred, but it is our opinion that Wheel Bugs are relatively docile as Assassin Bugs go and they are far less likely to bite than other blood-sucking members of the family and also some less threatening relatives that are much more likely to bite, like members of the genus
Zelus.  We have chosen to feature your submission as the Bug of the Month for October because of your awesome subject line and your dramatic letter, and because Halloween is this month and also because we got to mention blood-sucking.  However, we find your image a tad morose and though we will include the poor dead Wheel Bug in a Plastic Bag on Friday image, we suspect it was alive when you encountered it and we consider that Unnecessary Carnage.  We are taking the opportunity to post once again, originally posted in 2007, our favorite image of a live Wheel Bug which many folks write to us calling a Dinosaur Bug or Stegosaurus Bug.

The mechanics kept it alive and only temporarily put it in the bag as proof they got it out.
Thank you for informing me of its stinging bite, I stayed up all night researching it and closed mouth crying.
Best,

Hello again Terrified.
Thanks for letting us know.  We will remove the Unnecessary Carnage tag.  You have some pretty thorough mechanics for them to have gathered the evidence of the extenuating circumstances that led to your unfortunate accident.

We must thank you for cheering us up with your kind letter, and also because though we do not believe your image documents typical Wheel Bug mating, we are nonetheless thrilled to post it.  Probably the greatest reason your letter cheered us is that we just made a Wheel Bug posting Bug of the Month for October, but there is no reason we cannot add a second Bug of the Month posting for October, but with a more positive outcome for the Wheel Bugs.

Thank you, that was a strange bug!! And its not typical? I don’t know much about bugs, lol. However i did see one more picture of that bug with two of them on its back and it was called something like a mating frenzy haha.

Dear AJS,
This is an immature Wheel Bug, one of the Assassin Bugs.  In the spring, we often get identification requests for hatchling Wheel Bugs which resemble ants and stay in a group, and beginning in mid summer, photos of adult Wheel Bugs will begin to appear in our mail. Your photo is of an older nymph that has ventured from its siblings.  Wheel Bugs can bite if provoked, and the bite is painful, but they are advantageous predators.

How you want your letter signed:  Melba

Wheel Bug

Dear Melba,
Wheel Bugs do not sting, however we frequently caution our readers to handle Wheel Bugs with caution as they might bite, though unlike other Assassin Bugs, we rarely get reports of actual bites from Wheel Bugs.  Though the bite of a Wheel Bug is not considered dangerous, the local effects of a reportedly painful bite might last some time.

Hi Greg,
Often the identification of immature insects can be very difficult and your specimen is a nymph.  It is not a Leaf Footed Bug, but rather an Assassin Bug.  We are relatively certain this is a Wheel Bug, one of the larger Assassin Bugs that is quite distinctive as an adult because of the coglike “wheel” on the thorax that is not evident in the nymph.  Assassin Bugs are beneficial predators, but they will also bite humans if mishandled, and the bite is quite painful.

Sir,
My picture’s don’t clearly show the black sparkly tar like oval (I call her ”eye”) on the back of her wings. We watched her lay eggs, maybe? 2nd picture (blurry – sorry – I was freaking out about being that close to her), shows some of the shiny ”eggs” (I’m assuming they are eggs) she put on the post. Do you know what this is? If you need more pictures, and can promise me this thing just looks mean (but very cool!), but really isn’t, I can take more. It moved to a log on the porch, and hasn’t moved for days. My guess, she is still there. I avoid bugs, but this thing is just too interesting to not try to find out what it is. First saw her on Halloween. We live at the top of a mountain, along Michaux State Forest, and now she does too.
She looks like a stink bug/cricket combo that I’ve nick named dinosaur cricket.
Thank you for any information you can provide!

Dear Dana,
We love that you have named this native, predatory Wheel Bug the Dinosaur Cricket.  Wheel Bugs are Assassin Bugs and they are in the same insect order as Stink BugsWheel Bug Eggs are laid in a regular, geometric mass that resembles barrels.

Thank you for your response! That is exactly what she is!! With this new information, I can get more pictures of her and her glistening black “eye” on her wings. She didn’t lay a whole lot of eggs, but I hope to see more wheel bugs in the future, so I will be watching her eggs in the spring.
I think this is the first time I’ve ever thought a bug was cool, and happy it was on my porch.
It is the closest thing to a “dinosaur” that I ever want to see.  🙂
Thank you again!

Letter 11 – European Hornet attacks Wheel Bug

 

Bug help….
Hello,
A few months ago by using your website I was able to identify a mysterious bug I had never seen before sitting on my basil planter outside as a nymph wheel bug. Well, here we are a month or so later without having seen the wheel bug and we walk outside and find the now “adult” wheel bug sitting out on our deck right before we watched it get attacked and killed by a (European hornet?). Please identify the bug attacking the wheel bug in the attached picture. Thanks for your help!!!
B&D
Sellersville, PA

Dear B & D,
Your identification of a European Hornet, Vespa crabro, attacking a Wheel Bug is correct. According to BugGuide, the European Hornet is : “Predatory on other insects, used to feed young. … The workers capture insects, bringing them back to the nest to feed the brood. Workers need more high-energy sugary foods such as sap and nectar, and hornet larvae are able to exude a sugary liquid which the workers can feed on.”

Hi Again Terry,
Yesterday we wrote you a quick reply identifying your insect as a newly metamorphosed Wheel Bug, one of the Assassin Bugs. We have been thinking about your wonderful image, and wanted to post it. Sometimes time will not permit us to post everything we want to post, but we needed to revisit your submission. Many years ago, we received a similar, though very blurry photo. Your photo is so crisp and sharp and shows the orange coloration of the newly metamorphosed Wheel Bug as well as the black discarded exoskeleton. The orange color will soon darken. This Wheel Bug is still not mature. When it becomes an adult, it will have fully functional wings as well as the signature coglike wheel on its thorax.

Hi Spooked,
Prehistoric is a word that is frequently used by our readers to describe a Wheel Bug. Your letter is so delightful and descriptive. The Wheel Bug, Arilus cristatus, is one of the largest and most distinctive looking of the Assassin Bugs. They are predators and they are beneficial in the garden, but like all Assassin Bugs, they are capable of biting a hapless human and the bite is painful. You can read more about the Wheel Bug on BugGuide. It is the time of the month to select our Bug of the Month for November, and since we will be leaving town for a few days before the first, we have decided to select our winner from the pool of likely candidates early. Congratulations, your image of a Wheel Bug will be prominently featured at the top of our homepage for the entire month of November. Speaking of candidates, it seems we can’t rip our eyes from the news coverage lately, and your state has been so prominently featured. We can’t help but wonder if you have been cheering and waving signs behind one of the presidential or vice presidential hopefuls.

six legs, scorpion end, black & red/orange, walks like a walkingstick
Fri, Jun 26, 2009 at 5:36 PM
Hello!
This is my first submission of a picture to you, I think. Though I have used your site for years. Thanks! 🙂 We live in West Lafayette, Indiana and we found this bug on June 26th, 2009. We took several pictures – do with them what you like. I found this bug crawling up the side of an interior door frame in our house. At first glance, I was sure it was a spider. Then I could only find six legs and two long antennae. I also thought of a scorpion as its rump went up in the air. The way it walked reminded me of a walkingstick or praying mantis. It was black and bright red/orange. We tried to take pictures of it inside, then finally took it outside and got a few shots.
Please, do you know what kind of bug this is?
Thanks! 🙂 -Anne

This little critter kept coming to visit a photography class we were having. It looked like a spider, except for the rear end, which was held up like a scorpion holds it’s stinger. One of the staff at the park told us this was a stink bug, but I don’t really see a shield shape.
Thanks for any help you can give me in identifying it.

Wheel Bug Nymph

Hi Anne,
This is an immature Wheel Bug,
Arilus cristatus, and when it is fully grown, it is North America’s largest Assassin Bug.  When fully grown, it is easily distinguished from any other Assassin Bug by a coglike projection on the thorax.  You can find numerous images of adult Wheel Bugs on our website, including this example dating back to October 2009.  Wheel Bugs and Stink Bugs are both True Bugs in the suborder Heteroptera, so your observation has merit.  Additionally, Wheel Bug hatchlings, like this grouping sent this past January, are frequently mistaken for Spiders.  Wheel Bugs are one of our Top 10 identification requests, though upon viewing that tag, we realize that we have not added any new images of Wheel Bugs in years.

What is this ?
Location: Pool Cage – Tampa FL
April 15, 2011 1:24 pm
Hi There,
A friend told me of your site. Trying to identify this spider like bug in my yard. It is near my pool cage. We have never seen them in the 7 years living here. We now have had 8 over the last week. One of them stung my girlfriend on the wrist when she was sitting on the ground. It looked like a small puncture mark. She then had some aching and throbbing of her veins in her wrist. Then she has some discomfort extending up her arm. So, it seems like there is venom. BTW – we live in Tampa FL. Our house does not back into the woods. It is a settled neighborhood and we have houses on all sides of our property. I have spray some concentrated bug killer around the pool cage, but we are still seeing 1-2 per day. Today I killed 2 and I’m going to try seeing if I can find a local exterminator company that I can bring one that I captured in a jar. Any help from you is much appreciated!

Arilus cristatus, have recently hatched in many parts of their range, people are beginning to request identification information.  We have posted at least four letters with images of immature Wheel Bugs in the past week.  Your letter contains information about your girlfriend being bitten, and we have indicated that we rarely receive reports of people being bitten by Wheel Bugs, but that there is a possibility it will happen.  Wheel Bugs are beneficial predators and we would urge you not to spray needless pesticides.  We are linking to an image on BugGuide of a Wheel Bug feeding on prey so that you can see the piercing and sucking mouthparts.  We are preparing your letter and image in advance to post live during our absence from the office for several days next week.

Letter 21 – Immature Wheel Bug

 

Weird texas bug
Location: Houston, Texas
April 18, 2011 6:26 pm
I live in NE Houston, Texas, and I have an organic garden. I found this insect on a cucumber plant after having the sprinkler on for an hour or so, so I’m not sure if he was there seeking cover, or he is a pest on the cucumbers. I would like to know if it is a pest, or potentially beneficial, or neutral, I hate picking bugs off plants when I don’t know what they are!

Hi Jen,
This is an immature Wheel Bug nymph.  We have posted numerous images of immature Wheel Bugs in the past few days, and they have all been submitted from Florida.  Wheel Bugs are found in many parts of North America.  They are beneficial predators and you should return this individual back to your organic garden.

Hello Bugman,
We have quite a few stink bugs around our house this time of year (Clarksville, MD) and I found this one that resembles stink bugs though perhaps isn’t related? It is actually a large bug with a diamond-esque back with two smaller (though still large!) ones attached to its back. Pretty amazing, actually. Please let me know what this bug is!

Hi Andy,
These are Wheel Bugs.  They are members of the Assassin Bug Family Reduviidae in the suborder Heteroptera.  Stink Bugs are also Heteropterans, however, they are in the family Pentatomidae.  This is the second image of three Wheel Bugs attracted to one another that we have received in the past week.

Dear blonde girls,
This is an immature Wheel Bug, and we always warn folks to handle them with caution since the bite is reported to be quite painful, though not dangerous.  Thanks for your letter that supports our warnings.  We just posted a photo of an adult Wheel Bug, the largest North American member of the Assassin Bug family.  Assassin Bugs, including Wheel Bugs, are predators that use their piercing proboscis to suck the fluids from their prey.  Hapless humans might also be bitten though this is usually an accidental encounter, like your coworker, or a case of careless handling.

thats terrific! thank you for your repsonse, I was leaning towards wheelbug for most resembles, but it didnt have all the characteristics yet!!!

Hi,
I have always liked bugs… mostly the pretty ones, but I find them all interesting nonetheless. I have never seen this creepy little critter before and this year I have them all over my yard. They seem to especially like my mimosa tree. I live in eastern Oklahoma and I think I started noticing them around the beginning of June. I’ve asked several of my friends and none of them seem to know any more than I do!
Thanks for your help!

Dear AJ,
You were startled and disgusted by an immature Wheel Bug, a beneficial predatory species of Assassin Bug that might bite if carelessly handled.  We wonder if any studies have ever been conducted of the frequency of accidents caused by extreme reactions to insects, including stinging bees and wasps, that are discovered inside automobiles in motion.

Hi Daniel,
Thank you for the quick reply and providing me with the details on this bug.  I agree and also wonder if any studies have ever been conducted, I am curious to know.

Hi Anne,
Your image lacks critical detail, but this appears to be a Wheel Bug, the largest North American Assassin Bug, a member of a family of predators.  Some Assassin Bug in the genus
Triatoma, which are commonly called Blood Sucking Conenose Bugs or Kissing Bugs, pose a threat to humans because they can pass on the pathogens that cause Chagas Disease, however though they might bite, Wheel Bugs are not considered to be dangerous to humans.

Dear Hendersons,
Your study of mating Wheel Bugs is a tangle of limbs that would make a novice bug watcher suspect a sighting of some prehistoric, mutated creature.  This is a Perfect Halloween Feature, so we are making it the Bug of the Month for November 2014 and posting it early.  We wish you had a camera angle that could distinguish actual mating with mere coupling.

Dear Marilyn,
We believe this is the Egg cluster of a Wheel Bug, a species of beneficial predatory Assassin Bug.  The eggs will pass the winter and hatch in the spring.  Though Wheel Bugs are not aggressive towards humans, they might deliver a painful bite if carelessly handled.  Adult Wheel Bugs are quite distinctive looking.

Dear Aerin,
The primary insect in your image is an predatory, immature Wheel Bug, and it is possibly that it captured and fed upon the wasp that we cannot identify because of the angle in the image, but we find it puzzling that it would carry around its prey.  As Wheel Bugs have a mouth designed to suck food, they feed only on fluids and leave a dried husk as opposed to other types of predators that chew. 

Letter 32 – Wheel Bug bites woman in Georgia

 

Subject: please identify?
Location: Atlanta, GA
December 12, 2015 9:28 pm
dear bugman, i live 30 miles south of atlanta, ga and was up in my tea olive bushes cutting & shaping so i could hang the christmas lights from the gutters. i stepped down in the pine straw and felt something bite the back of my thigh! i grabbed the back of my bluejeans where i felt the bite and tried to squish ~ it bit me again. i ran in the house and as i got out of my pants as quickly as possible, i prayed, “please Lord, let me find what bit me!” Out dropped the bug i’m sending you the picture of below. it is about and inch and a quarter in length. The bite immediately stung like a bee – but quickly spread out to about the size of a dinner plate in area . it began to swell immediately. i made a poultice of baking soda and with everything in the news about the ‘deadly kissing bug’ drove myself to the ER. UGH – 5 hours later, they couldn’t figure out what the bug was. it left a hole in my leg – i can’t tell if its blood in the hole – it didn’t bleed – or what. gives me shivers to think too much about it. here on day 3, the round area of swelling had gone down but is back and now a rather odd shaped oblong patch that is beginning to itch terribly. i have an appointment in a week to have a blood test for changas but in my research have come across the fact that it hurts is a good indication that it isn’t a bad bug that spreads t-cruzi but i’m looking for some bug identification… please!!!

Wheel Bug
Wheel Bug

Dear Liz,
We are sorry to hear about your painful bite, but the good news is that this is NOT a Kissing Bug, but rather a Wheel Bug, and Wheel Bugs do not spread Chagas Disease.  Though Wheel Bug identifications are among our most frequent requests, and though Wheel Bugs are the largest North American Assassin Bugs, your report is the first in over 13 years we have ever received of a person being bitten by a Wheel Bug.  We have long suspected that a painful bite could result from carelessly handling a Wheel Bug, but unlike other Assassing Bugs that bite more readily, Wheel Bugs seem very reluctant to bite humans.  Your unfortunate encounter was doubtless due to the Wheel Bug finding itself trapped between your jeans and your skin.  Wheel Bugs are not normally aggressive toward humans.  Though we do not normally provide medical advice, in our unprofessional opinion, the blood test for Chagas is probably not necessary.

P.S.  We are not tagging this as Unnecessary Carnage being that it was suspected of being a Kissing Bug and having the specimen was necessary for a correct identification.

Thank you for taking your time in such a quick reply! Your answer really did help me. I wouldn’t recommend anyone else getting bitten by those little buggers for at least another 13 year! UGH.
Sincerely,
Liz Felten

This bug was in a flower bed in New Hope, Pennsylvania. My four year-old son didn’t see it before it bit his hand. It definitely caused him quite a bit of pain and the mark was noticeable, though it didn’t seem to have any signs of venom or poison in it. It happened today, June 30, on a very warm summer evening. The bug is about an inch long, silver and orange in color, and the tail was curved upwards, resembling a stinger (almost scorpion-like). Any help identifying it would be very helpful!!
Thanks so much!

Dear Lauren,
This is an immature Wheel Bug, one of the Assassin Bugs in the family Reduviidae.  With the exception of Blood Sucking Conenose Bugs or Kissing Bugs in the genus
Triatoma that are known vectors for Chagas Disease, Assassin Bugs are not considered dangerous to humans, however many species will bite readily.  Though we often caution folks to handle Wheel Bugs with care to avoid getting bitten, we very rarely get reports of bites from Wheel Bugs.  Other species of Assassin Bugs bite more readily.

Thank you so much for your quick and thorough response! It is great to know what this is and where it came from.
Have a great holiday weekend!!

Cog-Wheel Bug

Dear Charlie,
Your insect bears such a strong resemblance to the North American Wheel Bug that we are quite certain it is in the same genus.  Many years ago we posted an image of a mating pair of similar looking members of the genus that we tentatively identified as
Arilus carinatus, but we do not know how many members of the genus are found in Central America.  Right now we cannot access BugGuide to verify how many members of the genus are known.  Flicker has an image of Arilus carinatus that looks very similar to your image, and we strongly suspect that identification is correct.  A google book entitled Latin American Insects and Entomology by the amazing Charles Leonard Hogue has a drawing on page 223 of the Cog-Wheel Bug, Arilus carinatus.

  • I can personally vouch for this critter’s natural armament, having been shanked by them not once, but twice. DO NOT pick one up with an unprotected hand unless you enjoy the sensation of having a miniscule, live fire-coal buried in your skin for 30 seconds, and of the embers smoldering there for an hour or so afterwards.

    The worst of the pain may not last long, but it was more than enough to make me forget everything else around me for that first 30 seconds.

    If you’re wondering why I picked up a Wheel Bug twice, well, I didn’t. The first time was childish (and ignorant) curiosity; the second was poor lighting and poor choice of hand placement in propping myself against a brick wall…

  • True story, the first time I saw one of these it was running at me very aggressively while I was sitting on the sidewalk in front of my work. I poked at it with a pencil (which makes most bugs run off the other way) but the thing reared up and charged me again! I decided to let him have the sidewalk!

  • I found one in my house. My dog was almost laying on it, I thought my dog had actually brought in a stick and chewed it up, that’s how big it was. It must have been 3 inches long and the back of it was shaped just like a giant stink bug. I picked it up with my hand at first because as I said it looked like a chewed up stick at first, but when it moved in my hand I dropped it quickly and saw that the bottom of it had a red stinger like thingy on its but, do the bite or sting humans?

  • Hi we found a few on our deck that appeared to be the same bug. We were not sure what they were and kept one in a baggie. The larger one evidently flew away. They looked just like the photo here and we did let the small one go. They’re just intimidating and definitely don’t want to be stung by one. Thanks for clarifying what it is.
