Essig Museum of Entomology (EMEC-EMEC)

The Essig Museum of Entomology maintains ca. six million pinned, slide-mounted, and fluid preserved specimens of terrestrial and fresh water arthropods with a focus on western North America, particularly California. Other well-represented regions include Costa Rica, Chile, Australia, New Caledonia, Hawaii, and French Polynesia. The collection was formalized in 1939 with the launch of the California Insect Survey, although some specimens date back to the 1890’s. New accessions continue to add to our holdings through faculty, staff, and student research, and generous donations from insect enthusiasts and other collectors. The Essig Museum is part of the Berkeley Natural History Museum consortium.
