The U. S. National Insect Collection is the second largest insect collection in the world, with approximately 35 million specimens representing over 300,000 species. The collection includes over 100,000 holotypes and many additional paratypes and secondary types. The size and quality of the Nearctic and Neotropical collections are unparalleled, but there are specimens from all over the world, with especially strong representation from Sri Lanka, the Philippines, and Papua New Guinea. The specimens represent approximately 60% of the known insect families, with especially strong collections of butterflies and moths, flies, mosquitoes, beetles, and wasps. The majority of the collection is pinned or point-mounted and stored dry in drawers, but there are also many specimens housed in alcohol, on slides, and in envelopes.
