What's That Bug? does not endorse extermination

Look at what my cats found
July 13, 2010
They were getting along so I knew something was up. They found this running accross the carpet in my bedroom. First time I’ve seen more than a fly inside the house. The weather outside has been really hot the last couple of days, is that related?
Thanks, Devan

Red Flat Bark Beetle

Hi Devan,
Your photo is blurry which often makes identifications difficult, but we are relatively certain that this is a Pole Borer,
Neandra brunnea, one of the Long Horned Borer Beetles in the family Cerambycidae.  According to BugGuide:  “Larvae bore in trees, as well as structural wood (such as poles, crossties) in contact with moist ground. Adults frequently come to lights, though sometimes adults emerge, mate, and lay eggs in the same cavity they occupied as a larva“.

It is Cucujus clavipes.

Thanks Eric,
According to BugGuide, the Red Flat Bark Beetle,
Cucujus clavipes, is “Found under the bark of ash and poplar, especially recently felled trees” and is “presumably predaceous on other arthropods.

Hi Daniel,
Sorry about the camera but I can say that the pictures on that link look exactly like what I have in front of me.  You rock!
Thanks,
Devan

    Sorry but it is actually Cucujus clavipes – Red Flat Bark Beetle. Longhorns aren’t so flat.
