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


Iv only seen a couple of these recently. I can not figure out what it is. Can you identify it?

Hi, Patrick:

Thanks for including the image with your question.

The insect is an assassin bug in the family Reduviidae, genus Pselliopus .  Here's more about them:


I think they overwinter as adults, so perhaps the ones you found indoors were seeking a snug place to spend the winter.  No worries, they are not pests, or dangerous in any way (though they can bite painfully if carelessly handled).

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.
