The Behren's silverspot butterfly was first listed on December 05, 1997. It is currently designated as Endangered in the entire range.
The Behren's silverspot butterfly occupies early successional coastal terrace prairie habitat that contains Viola adunca (early blue violet), the larval host plant, adult nectar sources, and adult courtship areas. Several populations have apparently been extirpated, and the species likely remains at a single location near Point Arena, Mendocino County, California. It was federally listed as an endangered species on December 5, 1997 (62 FR 64306). Threats include invasion by exotic species, natural succession, fire suppression, residential development, and collection. (Federal Register: January 20, 2004 Volume 69)
