Mourning Cloak

Nymphalis antiopa

mourning1

Common names include Morning Cloak, White Petticoat, and Grand Surprise. It is called Camberwell Beauty in Britain and is a rare stray from Europe on the island.

This butterfly is found in North America, from south of the tundra to Mexico. Seldom found in Gulf of Mexico regions. It inhabits Europe and has been found in Siberia and Japan.

It is one of the first butterflies seen in the spring, emerging from hiding spots under leaves, rocks, crevises, where it hibernates as an adult. Often spring individuals will look very torn up or worn.

It is thought the Mourning cloak is one of the longest lived butterflies (N.America), with an estimated life of 10 months.

The fresh young are around for a short period and then go into a short summer hibernation (they estivate) before emerging again in the fall for a brief time.

Wing span: 2 1/4 - 4 inches (5.7 - 10.1 cm).

Caterpillar hosts: Mainly willows (Salix) but also know to use American elm (Ulmus americana), aspen and cottonwood (Populus), willows (Salix), hackberry (Celtis occidentalis), and paper birch (B. papyrifera).

Eggs are laid in groups circling twigs of the host plant. Caterpillars live in a communal web. Pupate and emerge as adults in June or July. Older caterpillars may be found wandering around or on non-host plants.

Habitat: Mourning Cloaks are known to be wide ranging and migratory. May be found in nearly any location where host plants occur.

Flight time is April through October/November, with peak numbers in July (for this region) as they young butterflies hatch out.
