The Entomology Collection of the University of Colorado Museum of Natural History contains approximately 800,000 insects and arachnids. It contains specimens from around the world, and it is especially rich in material from the Rocky Mountain Region. The strengths of our collection are the Hymenoptera (bees), Lepidoptera (butterflies), Coleoptera, Orthoptera, Hemiptera (leafhoppers), and spiders. Regional biological collections such as ours are especially important to the ecological and systematic communities because of their historical value, the concentration of collecting in a particular area, and their unusually excellent label data.
The Entomology Collection is located on the CU Boulder campus, on the third floor of the Bruce Curtis Building (MCOL). We welcome visitors who would like to use the collection. Please contact us at (303) 492-6270 should you wish to visit (directions). We are generally available by appointment from 10am–4pm Monday-Friday.
