Hi, in the previous 24-hour period, I have found 3 of these creepy crawlers. One in the garage and two on the front porch. It is about 1.5″ – 2″ long. It’s gray in color. If another photo is needed, I can take another photo. It seems like a cross between a stink bug and a spider (6 legs though).

Wheel Bug

Wheel Bug

Dear Rena,
Your image of a Wheel Bug is shot from an atypical perspective.  Most people take images from the side in order to feature the coglike projection or “wheel” on the thorax and many people describe the Wheel Bug as prehistoric and some have even coined the name Stegosaurus Bug.  The Wheel Bug is a beneficial predator, but they should be handled with caution as a painful bite might result.

Hi Daniel,
Thank you for the timely response and identification. I have pest control service coming out. If there was only one around, I wouldn’t have called but after finding three, I was afraid they could cause damage (of course not knowing what it was when I called). As a beneficial predator, what do they prey on?
Thank you,
Rena

Hi Rena,
They will prey on many species of insects.  We already provided a link to a Wheel Bug feeding on an invasive, exotic Japanese Beetle.

We have seen these in our backyard where the kids play didn’t know if they were bad?

Dear Lee,
This is an immature Sycamore Assassin Bug, and though they are not considered dangerous, they are capable of biting and the bite of a Sycamore Assassin Bug is reported to be painful.

Found this bug in Kokomo Indiana. It was carrying a hornet as young can see in the picture. Do you know what this could be?

Immature Wheel Bug

Immature Wheel Bug

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.

Could you help id this bug. Much like a grasshopper but has a scorpian like tail. Throws the tail over the back when mad. They are all over the stable which houses racehorses.

Wheel Bug

Wheel Bug

Dear Catherine,
This is a beneficial, predatory Wheel Bug that feeds on other insects.  It will not harm your horses, though we are very curious why there are large numbers of them near the stables.  Perhaps they are feeding on flies.

Thank you so much for answering my question. There are a lot of flies around the barns so they must love the atmosphere. Thanks again. Catherine

Can you help us figure out what kind of bug this is? Never seen one like it before.

Newly Metamorphosed Wheel Bug

Newly Metamorphosed Wheel Bug

Dear Thesouphead,
This is a Wheel Bug, the largest North American Assassin Bug, but what makes your image so interesting is the coloration.  Wheel Bugs are a dark gray, but just after metamorphosis, before the exoskeleton has a chance to harden, the color is much lighter.  Your Wheel Bug has just undergone metamorphosis from a nymph to a winged adult.

Found this crawling on my computer screen today. I had a window open, but still, not sure how It got in the house. I thought he might be a Praying Mantis, but the eyes have me baffled. Anyone know what this is?
Whatever it is, it’s in my garden now. He looked like a predator, so I wanted to give him a chance to do what he was made for. :)

Spiny Assassin Bug Nymph

Dear Kyrus,
This is an immature Assassin Bug, and though they are not related to Mantids, they share the physical feature of raptoreal front legs.  We believe your nymph is a Spiny Assassin Bug in the genus
Sinea, and you can compare your image to this image on BugGuide.
