Anthrenus museorum
museum beetle
Anthrenus museorum is a small dermestid beetle commonly known as the museum beetle. Adults measure 2–4 mm with round bodies and dark elytra bearing bright colored spots. The larval stage is the primary damaging form, feeding on dry animal materials including skin, hair, feathers, and occasionally dry food products like cheese, flour, or cocoa. The species is native to Europe and has become globally distributed through commercial trade, now occurring across the Palearctic, Near East, Nearctic, and other regions including China and Australia. It is a significant pest in museums, where larvae damage taxidermy specimens and insect collections.
