Description The Bog Copper or Cranberry-Bog Copper (Lycaena epixanthe (=Epidemia epixanthe)) is a North American butterfly in the family Lycaenidae. Adults like to sip drops of dew clinging to leaves and almost exclusively nectar on their host plant, Cranberries. Because of this, Bog Coppers will spend their entire lives within the area of a single acid bog. Even though their flight is weak and close to the ground, Bog Coppers are hard to catch because of the habitat in which they live in. Also, 85% of the Bog Coppers life span is spent in the egg.

The Bog Copper is the smallest U.S. copper. The upper side of the males wings is dark gray-brown with a purplish sheen (it glows under UV light very strongly). The male has very few black basal spots on the fore wing. The hind wing outer margin has orange markings. The upper side of the females wings is very similar to the males except the female has a lighter purplish iridescence. The underside of the wings in both sexes varies from whitish-gray to yellowish-tan. The wingspan measures ⅞ to 1 inch.

Dimensions 7/8-1" (22-25 mm).

Habitat Freshwater swamps, marshes & bogs.

Range Plains, Great Lakes, New England, Eastern Canada, Southwest, Mid-Atlantic, Western Canada.
