Each year around January-February, 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 Saturday, 8 February 2020, at the Essig Museum in UC Berkeley.
