Differentiation of Anthrenus fuscus from Anthrenocerus australis (Coleoptera; Dermestidae)

Accurate identification of pest species is the first line of defence for Museum IPM managers. Here we illustrate how to differentiate between two species that are on occasions found in museums and historic houses: Anthrenus fuscus and Anthrenocerus australis. The species can easily be differentiated with a microscope on the basis of antennal structure, or the presence of scales or hairs on the dorsum.
