Habitat:
Woodlands, woodland edges, parks, and rarely (despite the photos) in open fields taking nectar.

Overwintering Strategy:   Adult Butterfly

Flight:   
This butterfly has one brood which emerges in July, flies throughout the summer and fall, hibernates, and then flies and mates in the spring.

Caterpillar Host Plants:
Willows including Black willow (Salix nigra), and Silky willow (S. sericea); also American elm (Ulmus americana), Cottonwood (Populus deltoides), Aspen (P. tremuloides), Paper birch (Betula papyrifera), and Hackberry (Celtis occidentalis)

Notes:   
Although it is usually seen singly, the Mourning Cloak is a fairly common butterfly throughout Wisconsin and one that should be expected in every county.

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.
