Asked August 19, 2013, 8:02 PM EDT

A person I know found this bug. She said it made a hissing noise at them. I can't seem to find anything that would hiss.. a bore or a cutter don't from what I can tell. Could you please help us out.

Expert Response

It looks like an armyworm or cutworm, although a little difficult to tell from the pose. Neither of those - or any caterpillar I know of - would make a hissing sound. The Insect Diagnostician, Phil Pelletteri, at UW-Madison might be able to tell you more or offer an explanation for the apparent hissing sound. You can send the photo and question to him at and he should respond to you.
