description Mourning Cloak Overview

The mourning cloak, Nymphalis antiopa, is a large brush-footed butterfly found across much of North America and Eurasia. Adults have dark maroon-brown wings bordered by a row of blue spots and a broad pale yellow edge, while the caterpillars are dark, spiny, and often feed communally on willow, elm, birch, and related trees. Adults overwinter in sheltered places and can survive for many months, allowing them to appear unusually early in spring.
