scientific name    Lycaena cuprea    

common name     Lustrous Copper

Found along alpine gullies and streambeds, occasionally below treeline.

Adults are most often encountered between mid July and early August.

The bright, brassy uppersides are matched only by the Ruddy Copper (L. rubida), which lacks the many underside spots and occurs in prairie habitat. Alberta populations are appropriately assigned to subspecies henryae (Guppy & Shepard 2001).

life history
Little is known about the immature stages of this species. In the U.S., the egg is a dirty-white colour matching that of the rocks on which it is often laid (Scott 1992). The mature larva is green with faint markings, and the pupa is brown (Scott 1992).

Not of concern.

diet info
The larvae presumably feed on mountain sorrel (Oxyria digyna) and dock (Rumex spp.) (Layberry et al. 1998).

This species occurs in three population segregates, one in the coast ranges of central BC and northern Washington, the Rockies from Pink Mountain, BC south to northern New Mexico, and central Oregon to central California (Layberry et al. 1998, Opler 1999).
