Entomology (Study of Bugs)/is this a carpet beetle or something else


Tiny Round Black Bug
Tiny Round Black Bug  
I live in the United States in Pittsburgh, Pa.  My cat found this bug and chose not to eat it so I had squashed it. It seemed to me to make a slight crunch sound when I squashed it.  It looks like it is round, maybe 1/16 or 1/32 of an inch or less, has what appears to be two segments one small head and a larger body and appears to have six legs. It may have been slightly smaller than a ladybug in nature.  On closer examination, but barely noticeable it look like it may have had two faint brown stripes on its back.  I could not find a picture online to tell me for sure what it was.

Dear Michelle - The image quality is not sufficient for me to make a positive identification, but based on your verbal description, it may well have been a carpet beetle. If you encounter any others, please try to get a clear picture of its topside without crunching it. I suggest that you first place it in a small container and then put it in a freezer for a while. That will either kill it, or at least keep it from moving long enough for you to photograph it.

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.
