The Purdue Entomological Research Collection

The Purdue Entomological Research Collection (PERC) is an integral part of the Department of Entomology at Purdue University. Specimens housed in the collection are the basis for research in systematic entomology at Purdue and by specialists worldwide. The PERC also serves as a reference to facilitate the accurate and timely identification of insects for extension and teaching needs. Approximately 2 million specimens are held, representing more than 140,000 species. This includes mainly dry-mounted pinned material as well as many specimens stored in liquid preservative or mounted on slides.
