The Frost Entomological Museum is an active research institution, associated with the Pennsylvania State University's flagship campus in University Park. The museum houses a research collection, estimated at 2 million arthropod specimens, and a public exhibition and educational space. Although the museum was founded in 1969 much of the collection dates to the early 1900s and even the late 1800s. The research collection provides a record of the insect biodiversity of the Commonwealth of Pennsylvania and the eastern and southeastern United States. Major collection holdings include: Aphididae, Anoplura, and Odonata.
