Entomology (Study of Bugs)/What is this bug?


Mystery Bug
Mystery Bug  
I am trying to figure out what type of bug this is for a Biology lab. It looks like a beetle, but I can't find what kind of bug it is. It crawls. I'm in North Manchester, IN and this bug was observed on 09/20/14 at 1:45 pm in a dorm room.

Hi, Elizabeth:

Thank you for including an image with your question.  This is a "Western Conifer Seed Bug," Leptoglossus occidentalis .  Despite the name, this insect is now found coast-to-coast in the northern half of the U.S.

Here's a blog post I wrote about it:


and another:


These are at most a "nuisance pest" that does not affect the health of people or pets, or destroy property or crops.

Have a great school year, Elizabeth :-)

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
