Hi,
I found this bug nestled in my ceiling in my living room. I've never seen it before. Any idea what it could be?
Thanks!
Jay

Answer
Hi, Jay:

The insect in your images is either a Drugstore Beetle or Cigarette Beetle.  They are very similar and it takes at least a high resolution image (or better yet a specimen) to tell them apart.  Despite their names they are mostly pests of things other than tobacco and drugs:

Pantry Pests in general:

It is usually a matter of finding the infested item and discarding it.  Store vulnerable foodstuffs, including dry pet food, in metal, glass, or durable plastic containers with tight-fitting lids to prevent future infestations (or to contain infestations that occurred prior to purchase of a product).
