The male of this small butterfly (wing span of 1.7 - 2.5 cm) is dark brown with purple iridescence on its upper side. The female is duller gray-brown, often with bright orange margins. The underside is pale with some black spots and an orangey zigzag border on its outer edge.

Bog Coppers are in flight from mid-June to mid-July. In the Algonquin Highlands, you will only find them bogs and marshes, especially where there are Cranberries growing. Females lay their eggs singly on the base of these plants. The caterpillars are bluish-green with short white hairs and feed on shoots and leaves. First-stage caterpillars hibernate in their eggs, and are capable of submergence in water during hibernation.

Adult feed strictly on the nectar from Cranberry flowers.
