Entomology (Study of Bugs)/Beetle...Roach...I'm lost!!!



Mystery Bug....
These have been seen in my lower level laundry room and also in our garage.  They are black look like they are 3 sections. Very fast.  They come out in the dark more because when we moved a box in the garage, there were two that crawled away very quickly.  In our laundry room I have seen one here and there, our hvac unit is also in there.  They have six legs, the longer section being the 3rd back section.  I've uploaded a picture as well. It isn't the best picture, I made my husband pick it up (don't mind his dirty hands from working on his car).  I'm terrified its a roach!


Hi, Sarah:

No worries, this is not a cockroach!  These are ground beetles, family Carabidae, genus Harpalus :

Most are predatory on other insects (good!), but a few eat seeds of grasses, grain crops (not always so good).

Hope this helps.  I would let them be, as they will kill insect pests in the garage, garden, yard.

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.
