Identification of economically significant death-watch and spider beetles in Wisconsin
Snapshot: Two widely distributed beetle families, the death-watch (Anobiidae) and spider beetles (Ptinidae), include a number of economically significant species which cause damage to wooden materials and/or stored products. Distribution and abundance of several common species are known but the obscure lifecycle and small body size of many of these beetles often hinders identification. The purpose of this project was to develop a comprehensive list of all species in these families occuring in Wisconsin, and identify those which could potentially become problematic.
