The University of Arizona Insect Collection (UAIC) contains approximately 2 million specimens representing 35,000 species of pinned, alcohol-preserved, slide-mounted and frozen-tissue preserved arthropods mostly from the Sonoran Desert Region. Significant holdings include Coleoptera, Hemiptera, Hymenoptera, Orthoptera and Lepidoptera, but all insect groups are extensively represented. The UAIC user community is diverse, ranging from outstanding undergraduate and graduate students to highly active emeritus insect systematists. Annually, we host thousands of visitors, ranging from resident researchers to individual walk-ins, campus tour groups, and vast numbers of people seeking information on the biology of the Sonoran Desert Region.
