The Sierran East Slope subspecies, with greenish hindwing disc below; spots heavily silvered. Looks like a small S. coronis! On our transect occurs only at Sierra Valley, flying early like other callippe (June-July); visits Thistles, Alfalfa and yellow Composites. A moist-meadow species, presumably feeding on moist-meadow violets. Another colony occurs at the Donner Camp historic picnic site north of Sierraville on Highway 89.
