C. P. Gillette Museum of Arthropod Diversity

Committed to Teaching, Research, and Extension

Our museum houses nearly five million specimens. The collection represents most orders of insects with a strong coverage of Rocky Mountain and southwestern species. 

We house holdings of national importance in the aquatic insect orders:

  • Lepidoptera – butterflies and moths
  • Diptera – flies, gnats and former Center for Disease Control mosquito collection
  • Hymenoptera – ants, bees, wasps and relatives

Unique Holdings

The Collection houses 83 primary types and more than 2,000 secondary types. The associated Bruner Family Library contains important systematic literature.
