During the webinar, Dave Johnston will present The Incredible Ecology of California Bats, and Jack Owicki will introduce Critters That Shine in the Dark—With a Little Help from UV. Together, they’ll reveal a hidden nighttime world that many of us rarely get to see.

We’ll explore how bats navigate and forage in total darkness, the important pest-control services they provide, and the conservation challenges they face. We’ll also discover how ultraviolet light reveals glowing arthropods such as scorpions and millipedes, uncovering a surprising and beautiful side of nighttime nature.

This webinar is intended for beginner and enthusiast naturalists from the San Francisco Bay Area and beyond. If you’re a little uneasy about bats, scorpions, or walking in the woods at night, this webinar is for you, too! You’ll learn how fascinating these animals are—and may even feel more comfortable encountering them after dark.
