Each year in January, the Pacific Slope chapter of the Lepidopterists Society gathers at either the Essig Museum at UC Berkeley (even-numbered years) or the Bohart Museum at UC Davis (odd-numbered years). Guests chat, exhibit specimens, use the museum collections to help identify their own materials, and enjoy presentations on a wide range of Lepidoptera topics. There is no particular program for the day and guests are free to come and go.
The next gathering is scheduled for late January 2020, at the Essig Museum in UC Berkeley. Contact essig.museum[at]gmail.com for more information.
