Entomology (Study of Bugs)/Bug?


I found this in my bed this morning and I was wondering what it is?  Do I need to do something about it? Will it bite? etc

Any information would be greatly appreciated!


Hi, Jessie:

Thanks for including the nice image with your question.  This is an adult "carpet beetle" in the genus Anthrenus .  With your permission, I'd like to use this image in a blog post I have already published about these insects.  Here's the post, with more information about them. You can see my images aren't the greatest, and yours depicts a more common species, actually.


No, the beetles do not bite.  Be on the lookout for the larvae, as they can be a pest in stored products like dry pet food, cured meats, taxidermy mounts, wool blankets and garments, silks, furs, and other animal-based products.

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.
