Lycaena heteronea Boisduval 1852

No obvious concerns.

One yearly flight, peaking in mid July.

Central BC and southeastern Alberta south to California and northern New Mexico (Opler 1999). In Alberta, primarily found south of the Crowsnest Pass (Bird et al. 1995).

The males of this species are the only coppers that are blue, and it is therefore more likely to be confused with the blues than other coppers. The greyish-white underside will distinguish both sexes of the Blue Copper from other blues and coppers: the forewing has very prominent black spots, while the hindwing markings are faint or absent.

Dry montane meadows and hillsides.

The larva is pale green with a covering of short hairs and pale lines (Layberry et al. 1998). The pupa is green with brown spots, and the egg presumably overwinters (Bird et al. 1995). Males patrol rather than perch, and visit damp earth (Bird et al. 1995).

Larvae feed on buckwheat (Eriogonum spp.) in the western states (Opler 1999). Subalpine and Sulphur Umbrella-Plant (E. umbellatum and E. flavum) are the most likely hosts in Alberta.
