Plant Galls for the Curious Naturalist

September 7, 2022 @ 5:30 pm - 6:30 pm

| Free

Galls are intriguing plant structures. This webinar will explore this unique biology.

Join BioBlitz Club, Jumpstart Nature, and Keep Coyote Creek Beautiful for a special webinar about plant galls! 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! This event is scheduled in the middle of Gall Week 2022 – a global event aiming to document gall diversity worldwide.

During the webinar, 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.

This webinar is intended for beginners looking to better understand and learn how to find galls, as well as gall enthusiasts who are already exposed to the diverse world of galls, and would like to learn more. Even though the webinar will include many West Coast species, principles and approaches apply to most locations, so everyone is welcome to join in!

NOTE: Even if you are not able to attend, please register so you can receive the YouTube link to the recorded video, which will be released within a couple of days of the event.
