BugFilter: What is this giant bug?

July 11, 2005 5:13 PM

BugFilter: What is this bug? It was crawling around outside my apartment here in Austin and actually walked toward me whenever I would move, which creeped me the eff out. It's about two inches long and... just check out the photo. It was a slow and deliberate mover. I have to know what it is, and if I should keep a weapon nearby in case it comes back.

It looks like, and the description is compatible with, a borer beetle, family Cerambycidae (long-horned beetles) of which there are thousands of species so no idea which one. They (or their larvae) bore into trees or dead wood. The introduced Asian long-horned beetle is currently the source of panic here in the Northeast (but yours isn't one of them, although somewhat similar appearance). They're all completely harmless if you aren't made of wood.

I think it's a Cottonwood Borer, so TimeFactor is correct. And yes, it's harmless - it's not all that serious a pest even for trees.

I think TimeFactor has it. Closest thing in my handy-dandy field guide is a cottonwood borer.

Ah, the article says they emerge in June or July, so maybe he was just disoriented. He was moving a little awkwardly. Thanks for the help.
