Spring White
Pontia sisymbrii
This high elevation, early-spring mountain species apparently resides only along the Gabilan crest in east Monterey County. Much of this landscape is private property; at this time, the only known localities for this species are in Pinnacles National Park, where it is often seen, on good weather days in March-April, in the Chalone Peaks area. Pinnacles Ranger Paul Johnson has found its host plants on the east side in San Benito County.
Numerous searches for this species at other access points - Fremont Peak State Park, Gloria Road, and Highway 198 - have been unsuccessful.
