The California oak moth (Phryganidia californica) returns to the Cal campus for the second year in a row. The summer generation moths will give rise to late summer caterpillars that will attack coast live oak trees.

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

Each year we host three events when we open our doors to the public: Darwin Day (February), Cal Day (April), and Homecoming (October). Each has a slightly different focus.   As a research collection, the Essig Museum does not have

Following guidelines set forth by UC Berkeley and the State of California, beginning 17 March 2024, the Essig Museum is effectively closed for the next several weeks.  There will be no on-site identification services, specimen loans issued or received, or curation, as staff will be working remotely. We have access to email and can respond to data requests, but all on-site operations are suspended until further notice.

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.

            	                    Dragonflies are amazing arial predators, but like many insects they can get too cold to fly. This guy was found early one morning and is using a strategy of wing vibration to warm his flight muscles up. #odonata #dragonfly #insect #vibratingwings #thermoregulation

            	                    The Cecropia moth (Hyalophora Cecropia) is North America's largest native moth, and belongs to the family Saturniidae. Aaron Pomerantz is a PhD candidate at UC Berkeley who studies how wing patterns develop in giant silk moths. He has used the Essig Museum collection of Saturniidae to compare how wing patterns evolve across this charismatic family of insects.

            	                    It's national moth week everyone!  In celebration, here is a noctuid moth. They are subtle and unassuming, but upon closer inspection you see beautiful hints of orange in its complex pattern. Fun fact: its genus Hecatera references a Greek goddess of the underworld, Hecate.
