Description The Blue Copper or Lycaena heteronea has a greyish-white underside that distinguishes 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.
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.
Dimensions 1 1/8-1 1/4" (28-32 mm).
Habitat Canyons & caves, Forests & woodlands.
Range California, Northwest, Southwest, Rocky Mountains, Western Canada.
