The J. Linsley Gressitt Center for Research in Entomology is the premier collection of Pacific insects in the world. No other collection has the holdings, the scope, or the representation of specimens from the Pacific and surr­ounding areas. Greatest holdings are from the Hawaiian Islands, SE Asia, New Guinea, and the Philippines. The collection houses an estimated 14 million specimens and holds over 17,500 types mostly from the Pacific, but also those resulting from early Hawaiian-based biological control explorations from around the world.
