Butterflies of the Sierra Nevada


General Description:

The Sierra Nevada is rich in butterflies, and the Yuba Pass area is no exception. As many as 70 species of butterflies may be found on a single day by visiting 3 or 4 locations in a sequence of elevations. More than 100 species of butterflies have been located from the lower elevations near Camptonville over the pass to near Graeagle, including the campus itself... see Butterfly List

We will study the ecology, behavior, life zones, flower visitation, and life history of the area's butterflies in several elevational habitats. The instructor will use non-lethal means to study the butterflies, including netting, placing live butterflies in small containers, followed by their release; observation with close-focusing binoculars; and close-up photography. The goal will be for you to familarize yourself with the butterfly species seen during class trips and to learn about butterflies of different families and to understand their behavior, and ecological place in the environment. You should be able to stalk and study butterflies as well as to take recognizable photos.

Evening or morning slide talks will supplement the course by including topics such as intorduction to butterflies, local butterfly identification, western endangered species conservation, Monarch life history and tagging studies, butterfly gardening, and moth diversity and biology.

"We will take short hikes, but on one or two days they may be a bit rigorous. Many of our trips are on dirt roads, and particpants may be asked to drive or car-pool."
