Entomology (Study of Bugs)/Small black bug found on bed today



This morning I found a small black bug sitting motionless on top of a blanket that was folded on my bed. I put it in a small plastic container and observed it to be shiny black, looks a little like a beetle, and unfolds wings but hasn't flown (maybe it is exhausted I'm not sure).

I hope very much that it is unrelated but last night while sitting on my bed I got a few itchy spots, very small red bumps that I thought look like mosquito bites. Would this bug possibly be one that likes to bite? It is the only one I found.

Dear Patty - This is indeed a small beetle, and thus almost surely would not be responsible for any of your bite symptoms. I cannot tell for certain from your images, but it might be a black carpet beetle or a relative. Be on the lookout for slender larvae having a bristly 'tail' as in this image:
 If you find any, see for some control recommendations.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
