Essig Museum of Entomology, Entomological museum at University of California, Berkeley, US.
The Essig Museum of Entomology is a research facility at UC Berkeley housing millions of insect and arthropod specimens from around the world. The collection focuses on species from western North America and the northern neotropics, with particular emphasis on regional biodiversity.
The museum originated in the 1880s as part of UC Berkeley's University Museum and expanded significantly after becoming the California Insect Survey in 1939. This transformation enabled more systematic research and expanded collecting efforts across the state.
The collection serves as a central reference for understanding California's insect diversity and how populations shift due to environmental changes. Visitors can observe how researchers document these changes and why this work matters for the region.
Research visits require advance arrangements with the Collections Manager, while general public access is limited to special events such as Darwin's Birthday and Homecoming Weekend. It is best to contact the facility ahead of time to confirm current visiting opportunities and availability.
The museum maintains significant collections of specimens from the Pacific Islands, a region with exceptionally high endemic species diversity and critical conservation needs. This focus makes it an important resource for understanding the threatened biodiversity of these remote areas.
