Dear Bugman,
Could you help me find the name of this bug we found in a park yesterday.
Thank you very much.

Hi Emma,
This is a Wheel Bug, the largest Assassin Bug in North America.  While Wheel Bugs are not aggressive toward humans, they should be handled with caution as they are capable of inflicting a painful bite.  We have been receiving many more Wheel Bug identification requests than usual this season, which causes us to suspect that they are more numerous than usual.

Thank you very much for taking the time!

  1. I found one last year that had a Japanese beetle in its clutches, so I was curious what it was. Now I see the wheel bug nymphs all over the place and I know to leave them alone.

  2. I saw one on my house the other day. I thought it was a queen stink bug! The a friend said she saw one at work. Glad w didn’t touch it!

  3. Found a wheel bug in Manassas, VA – I’ve lived in Northern Virginia all my life and have never seen a bug like this. Quite interesting!

  4. I didn’t see a single Wheel Bug this year, or any Preying Mantis. There were a lot less Japanese Beetles as well, I think there’s a connection.

      • I had read an interesting article (on the interwebs) that plants under attack can give off “distress signals” to warn their neighbors, who in turn, will initiate whatever defenses they have, and also pass along the signal which will eventually attract predators. But we also had a brutal winter.
