Common NameCalifornian Granite
SeasonalityApparently double brooded in Alberta, with peak flights in late May and early June, and again in late July to early September.
IdentificationThis species is uniform brown-grey in colour with faint costal wedges and transverse lines; although the dark markings vary somewhat, this is one of the most nondescript species in the genus. Genitalic disection may be required to confirm identification (see McGuffin, 1972).

This species is uniform brown-grey in colour with faint costal wedges and transverse lines; although the dark markings vary somewhat, this is one of the most nondescript species in the genus. Genitalic disection may be required to confirm identification (see McGuffin, 1972).
Life History

Conservation
Further habitat and distribution data are required before status can be assessed.
Diet Info
Larvae feed on Lotus crassifolius (Scoble 1999), which does not occur in Canada. Presumably other legumes are used in Alberta.
