The Illinois Natural History Survey Crustacean Collection is one of the largest state collections of crustaceans in North America.
The collection contains primary types of 13 species and secondary types of 20 species. The collection contains over 135,000 specimens and 17,500 lots of approximately 400 species in 30 families. Almost all are from North America. About 50% of the collection is from Illinois; the remainder is mostly from the southeastern United States. The best represented groups are crayfishes, shrimps, scuds, slaters, and pill bugs. A few lots of marine crustaceans found along the North American coastline are also present in the collection. We also maintain a tissue collection that contains high quality tissues from a portion of our vouchered specimens, mostly those collected after 1998.
