Eight-eyed Expedition

We need your help. This project will collect and sequence the genomes of native Tetragnatha spiders found in California to better understand the spatial organization of genetic variation in these species, known as their ‘genetic structure’. The spider family Tetragnathidae , the

Restoration Project

Plants on campus provide food and shelter for a variety of arthropods, birds, and other urban wildlife. The Essig Museum is working with students and the campus landscape team to restore native plant communities around the Valley of Life Sciences

Holdings & Databases

Essig Museum staff and volunteers have been building several databases, including a list of species and specimens in the collection. Digitizing activities were greatly amplified by the CalBug project (2010-2015) funded by the National Science Foundation. For many specimens, labels

Public Events

We have not been able to host our typical public events this year due to the coronavirus. So we are going virtual. Join us on Wednesday, December 16, for a virtual tour and a look at insects under the microscope.

During the coronavirus pandemic

Following guidelines set forth by UC Berkeley and the State of California, beginning 17 March 2020, on-site services at the Essig Museum are suspended until further notice. Specimen loans and curation are limited as staff are mostly working remotely. We have access to email and can respond to data requests.

Our Mission

The Essig Museum of Entomology on the campus of the University of California at Berkeley houses an active research collection of over 5,000,000 terrestrial arthropods. From humble beginnings as a teaching collection over a hundred years ago, through exponential growth as the California Insect Survey beginning in 1939, the Essig Museum is now one of the largest and most important university-based research collections of insects in North America. Primarily a collection of specimens from the Western Hemisphere, regional emphasis is on the eastern Pacific Rim, in particular California, Mexico, and Central America, and the islands of the central Pacific. The mission of the museum is utilization of the collection to facilitate and document research, teaching, and outreach in arthropod biology. We are committed to making the information contained in our collection as accessible as possible to researchers, students, and the nonacademic community, and actively pursue interactions which will foster this development, within the Berkeley Natural History Museums consortium, as well as nationally and globally.
