Hi Carrie,
Your insect is a beneficial predator known as a Milkweed Assassin Bug that will help keep your plants pest free, though they will also prey upon beneficial pollinating insects.  Treat the Milkweed Assassin Bug with respect as they might give a painful bite if carelessly handled.

Ambush Bug

Bizarre yellow bug with red eyes!
September 14, 2009
We found this little guy/gal (1/4 or 1/8 of an inch long) on some flowers in the yard. I have never seen anything like it before in my life. Does anyone know what the heck this thing is?

Ambush Bug

Hi Nessa,
This is a predatory Assassin Bug known as an Ambush Bug.  Not too long ago, Ambush Bugs were classified in their own family, but they have recently been downgraded to the subfamily Phymatinae of the Assassin Bug family Reduviidae.  True to their name, the camouflaged Ambush Bugs will wait on flowers until a pollinating insect arrives to feed.

Wheel Bug trapped in Spider Web

Mean Looking Armored ?
September 13, 2009
I found this bug in a web on my fence walkthrough. I have never seen anything like it. 6 Legs, “Spiky armor” down it’s back. and it’s head is like a needle. This is one mean looking bug! I don;t know weather it made the web or just got caught in it. On it’s lower-side, very back there is a red spot and it seems that it’s dripping down the web in the photos.

Corsair Assassin Bug: Unnecessary Carnage

Beetle (?) Identification
September 13, 2009
A few days ago, I noticed one of these flying around the living room, and at first thought it was a yellow jacket. Yesterday, there were two, and today I’ve killed 3!
I’ve about worn myself out looking at bug sites and image searches, and thought you might be able to help. I’m not sure if its the recent rain, or the long drought proceeding it that has brought them inside.
Looking around, I thought they looked a bit like soldier beetles, but with opposite colorings. They are about an inch long, and seem to be attracted to the lights.
The bug in the pictures has been squished, but hopefully the markings are enough!
Thanks!

Corsair Assassin Bug Carnage

Corsair Assassin Bug Carnage

Dear Sarah,
Though they are not aggressive, if they are carelessly handled, Assassin Bugs in the genus Rasahus, known as Corsair Assassin Bugs, can bite painfully.
Despite this fact, we still feel that these beneficial predators need not be killed unnecessarily, leading us to classify your letter as Unnecessary Carnage. Based on images posted to BugGuide, we believe your individual is Rasahus biguttatus.

Bug on goldenrod
September 13, 2009
Photographed this guy/gal on a goldenrod plant along driveway–think it’s gorgeous and would like to know what I’m admiring. Also want to enter photo in competition and need ID to accompany it.

Hi Sue,
There is an entire ecosystem that thrives when the goldenrod blooms, from the nectar and pollen seeking creature, to the predators that prey upon them.  This is an Assassin Bug in the genus Pselliopus, probably Pselliopus cinctus.  According to BugGuide it is often found where insects visit flowers.

Thanks so much for your reply.  I sort of thought it was an assassin bug based on what I could get from my insect guides.  Sue

Mating Wheel Bugs

September 10, 2009
Just found these and searched for over an hour to find out what they are! I’m happy to say they’re beneficial in my yard, and thankfully I’m not a bug killer in the 1st place unless necessary. Would you like to add the photos to your collection? My 5 year old son is fascinated by them. Thanks for a great web site, its our go to for our bug questions.

Jagged Ambush Bug

13mm, green, armored tank/assassin bug-like body, with mantid forelimbs and a turtle head.
August 26, 2009
Hello again Bugman!,
Love your site.
I was looking over a stand of ragweed today, admiring all the activity, when I noticed there was a dead fly on one flowerheads, so I began looking deeper, in between the flowers, for a crab spider or something like that…and found this instead. It was scrunched down between flowertops as if lying in ambush. When I spread the flowers apart, it came walking out and stepped right up onto my finger. Didn’t seem to mind me photoing it numerous times, and even let me move it to the B-B-Q grill for better contrast. It only flied away when I tried to move it back to the ragweed. It’s about the same length as my fingernail (included for scale). I’ve never seen one of these before, but it does bear strong resemblance to the assassin bugs, except for it’s head, which is entirely different, looking more like a sea turtle from a Pixar movie. It has forelimbs like a mantid, or possibly a tiny cicada. It was also pretty hard to the touch like a stinkbug, and kind of weighty for it’s t iny size.
Mostly translucent green with a dark band across it’s abdomen, and a hard bony shell of a thorax which has a couple of knobs that protrude forward and up much higher than it’s head.
In a word, handsome.
Thanks much, Jeff Volpert

Ambush Bug

Ambush Bug

Hi Jeff,
It would seem that Ambush Bug is an apt common name for your insect based on your letter.  Recently Ambush Bugs have been downgraded from a family to  becoming a subfamily status of the Assassin Bugs, Phymatinae.  Your specimen is one of the Jagged Ambush Bugs in the genus Phymata.

Slow Moving, Non-Flying Bug at Hummingbird Feeder
August 14, 2009
Hi! Thanks so much for this site! It’s fabulous!
This insect appeared at a hummingbird feeder and seems to have a probiscus. It was challenged by a hummingbird whilst at the feeding station and lifted up its two front arms but tucked its head and probiscus under. It appears very gentle, moves VERY slowly and likes to drink sugar water. When not feeding, it perches on the top of the feeder, hanging off the sides. It doesn’t seem to mind direct sunlight. It also appears to have bilateral eyes at the tip of an eye stalk. The probiscus curls under, like an elephant trunk. What on earth is this?

Wheel Bug

I finnally got a chance to see one in REAL LIFE!
August 13, 2009
I never thought I’d ever actually get the chance to see a wheel bug, but I finally did get my chance! How Cool! They are smaller than I pictured. I was in Lake Ozark, MO. THEY WERE EVERYWHERE, ( including on the inside of some muscle-mans shirt. ) ( he freaked out and killed one! I wasn’t happy about that, but my mouth is too big for CPR! ; P

Hi Sherri,
We are thrilled to hear that a Wheel Bug sighting made such a big impression on you.  Your muscle man story reminds us of the old header we had on our Unnecessary Carnage page when we used Dreamweaver to post information to our website, prior to our site migration.  We are working with our web master to get this introduction as a header on the Unnecessary Carnage page once again.  Here it is.
Insects are prone to unnecessary slaughter, be it from an overzealous homemaker who doesn’t want to see bugs, or from a strapping he-man who is a closet arachnophobe, or from a youngster who likes to torture. At any rate, we get a goodly amount of photos of poor arthropods whose lives ended prematurely. In an effort to educate, we present Unnecessary Carnage. This page is not intended for the squeamish.

Hi Patrick
Your newly metamorphosed Wheel Bug will turn black or dark gray when its exoskeleton hardens.
The colors of your photograph are quite striking.

Immature Hemipterans on Cicada Exoskeleton

Litte red bugs, on a cicada shell?

I found these little red bugs which look like ants with tiny antennas all over a cicada shell. I have no idea what they are!

Hemipteran Nymphs on Cicada Exoskeleton

Hemipteran Nymphs on Cicada Exoskeleton

Dear Shannon,
All we are able to determine from your photo is that these are immature Hemipterans, but why they are on the Cicada exoskeleton is the curious question.  We believe the Hemipterans might be immature Milkweed Assassin Bugs, but your photo lacks the detail necessary to be certain.  It is possible there were fluids left after the Cicada metamorphosis, and the Assassin Nymphs are feeding on the fluids.

Assassin Bug Nymph

Tiny, spiky bug
July 30, 2009
This little guy came inside with some flowers and I almost missed him as he was crawling around on my furniture. He was truly minute; my camera didn’t even pick up on him so the picture quality is bad. As a size reference, he literally had to climb up onto the white placemat in the picture. You’ll be happy to know I took his picture and then carefully carried him back outside on a leaf and put him back on the flowers.
As cute as he was, he probably would have been pretty scary looking if he had been bigger. You can see he is covered in spikes and he had a pretty severe proboscis. I don’t even know where to start looking as far as how to identify him. Thank you for you help.

Hi Lisa,
This is an immature nymph of one of the spiny Assassin Bugs in the genus Sinea that is well represented on BugGuide.  It sounds like you are a gardener, so you will be happy to know that Assassin Bugs are important predators, but they must be handled with caution as they will bite and certain species are reported to have very painful bites.
