Explore the butterflies of Cascade Canyon, a lush preserve tucked into the hills above Fairfax, and one of the gems of the Marin County Open Space System. Its 500 acres has some of the most pristine habitat in the Corte Madera Creek watershed. From swallowtails to checkerspots and blues, we will search for a variety of species and observe behaviors like puddling, nectaring, and maybe even egg laying. We’ll also take time to learn to recognize various host plants like California pipevine, ocean spray, sticky monkeyflower and purple needle grass as well as favorite nectar plants including yerba santa, blue dicks, and buckeye. This class is excellent preparation for the North American Butterfly Association annual butterfly count in June, the butterfly community’s equivalent of the Christmas Bird Count. Also open to youth (age 10-17) with adult attendance.
