Finding and Appreciating Bay Area Plant Galls 
Wednesday, September 21, 2022 07:30pm

Galls are intriguing plant structures induced by insects (usually), creating a sheltered home for the larval stages of the inducing organism. They have diverse and sometimes incredible shapes and colors, and their natural history is equally fascinating, with complex life cycles, tiny parasites, and more!

Michael Hawk (Nature's Archive podcast and Jumpstart Nature) and Dr. Merav Vonshak (BioBlitz Club) will talk about gall biology, common host plants and gall inducers. They will discuss how you can find and identify galls, with numerous examples including gall look-alikes.
