This preserve is a great spot to see a variety of butterflies: Blues, swallowtails, admirals, sisters, buckeyes, checkerspots, crescents, and many more. We’ll take the time to observe them as they go about their business of finding nectar, attracting mates, detecting the proper plants to lay eggs on, and engaging in a practice called “puddling”. If you’re not sure what “puddling” is, you’ll have to join us and see. Remember to bring binoculars, if you have them. This lecture is intended for ages 15 and up. We request that no pets (except service animals) attend. High fire danger cancels: Call (415) 893-9527 after 8am on the morning of the event to hear a recorded message if cancelled.
