Bay Nature Hike: Evening Mothing Workshop with Allen Fish and Cat Chang

Join Bay Nature with expert naturalists Allen Fish and Cat Chang for an evening mothing workshop at Tilden Park Environmental Education Center on Saturday, June 27 from 8:00–9:30pm. Inspired by Bay Nature’s Spring 2026 story “Putting On Your Moth Goggles,” this hands-on program will introduce participants to the surprisingly beautiful and diverse world of moths hiding in plain sight around us.

The evening will begin with an introduction to mothing basics, including equipment, observation techniques, and how to start noticing moths in your own neighborhood and outdoor adventures. Allen and Cat will share learning handouts, answer questions, and discuss the growing community of people discovering nocturnal insect life through curiosity and close observation. After sunset, we'll gather for live observation at mothing sheets set up around the Environmental Education Center. June is one of the best times of year for moth activity, and we’ll hope for a warm evening with plenty to see.
