Entomology (Study of Bugs)/Can not identify this bug


Hello! I saw this pesky bug crawling on my arm and it concerned me. I'm not sure what it is and if there could be more. It is very small, the shape of a lady bug, but smaller. It appeared brown with white spots. Thank you for your time and help!


Thank you for including the image with your question, though it was clear to me from your description what you were talking about.

This is a carpet beetle.  Easily 80% of the questions I receive are about these insects.  Here is a blog post I wrote about them that should answer most of your questions:

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.
