Bog Copper, Lycaena epixanthe

Bog Copper

Lycaena epixanthe

Description:
The male is brown above, with a purplish sheen on fresh specimens, a larger spot in the middle of the upper wing, and several smaller spots. The female has many more spots, and the spots are usually all similar in size. Below, the ground color is pale, with a reddish submarginal zigzag pattern on the hind wing.

Habitat:
Acid bogs where cranberries are present.

Overwintering Strategy:   Eggs

Flight:   
One brood from the end of June through July.

Notes:   
The Bog Copper is the smallest Copper found in Wisconsin. It is found exclusively in bogs where wild cranberry, its host plant grows. It is a very weak flier and typically flies very low to the ground in the wettest parts of the bog.

Overwintering Strategy

Two-way migration: Adult migrates from Wisconsin to Central Mexico
Small migration: Adult migrates from Wisconsin to southern US
Immigrant: Adult migrates into Wisconsin from warmer areas and don't fly south in winter
Adult Butterfly: Hibernates overwinter as an adult butterfly
Eggs: Eggs laid on stems, twigs or foot plants overwinter in diapause
Caterpillar: Caterpillars make nests on the base of plants and hibernate until spring
Chrysalis: Caterpillars shed their last skin, form a chrysalis and enter diapause.
