The Field Guide to California Insects has been updated and republished by UC Press with all new photographs. Originally published by Jerry Powell and Charles Hogue in 1979 (reprinted in 1982) with illustrations by Charles Hogue, this field guide remains
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

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.
