Wheel Bug Stalks Stink Bug

Giant Stink Bug?

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.

  1. [...] there was no place to upload pictures! Just wanted to say how excited I am that you’ve chosen the Wheel Bug as the Bug of the Month! I sent in a picture to be identified back in Nov. 2008 and have followed my wheel bug family ever [...]

    I found and took a picture of a wheel bug, in western Pennsylvania on about the same day…I am not sure how to post pictures, but, I am just wondering, did they all have a convention of sorts, because I had never seen on before in my lifetime.

    The green eyes fascinated me! So happy to find it to be bug of the month…they must have decided they were due some recognition!
