Varied Carpet Beetles
Dear Tina,
These are Varied Carpet Beetles, Anthrenus verbasci, a common household pest. According to BugGuide, the larvae of Carpet Beetles “feed [on] keratine and chitine, and may cause considerable damage on wool, fur, feathers, and natural history collections.“ Most of the identification requests we receive at What’s That Bug? are of the larvae or of the emerged adults that congregate around windows in an attempt to gain access to the outdoors. They die on windowsills in great numbers. The adults feed upon pollen and do not cause any damage in the garden or indoors.
