Discussion
Variety auriculatum is a highly variable taxon that occurs along the coast and in the adjacent mountains (Alameda, Contra Costa, Humboldt, Lake, Marin, Monterey, Napa, San Benito, San Francisco, San Luis Obispo, San Mateo, Santa Clara, Santa Cruz, Solano, Sonoma, and western Stanislaus counties).
A related and as yet undescribed variety, known only from the Antioch sand dunes area of Contra Costa County, California, is the host for the federally endangered Lange’s metalmark butterfly (Apodemia mormo langei).
