|scientific name Digrammia californiaria |
common name Californian Granite
Occurs in prairie badlands.
Apparently double brooded in Alberta, with peak flights in late May and early June, and again in late July to early September.
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).
Poorly known. It appears to be double-brooded. Adults are attracted to light.
Further habitat and distribution data are required before status can be assessed.
Larvae feed on Lotus crassifolius (Scoble 1999), which does not occur in Canada. Presumably other legumes are used in Alberta.
Southernmost BC and Alberta south to California (McGuffin 1972). In Alberta it occurs in the grasslands region, north to Tolman Bridge on the Red Deer River.
