Dun Skipper, Euphyes vestris

Dun Skipper

Euphyes vestris

Description:
Below, this skipper is mainly a black species with just a hint of a lighter spot band on the hindwing. Both the male and female are very dark from above. The male has a barely-visible stigma that blends in with the dark color of the wings, while the female usually has two very tiny light spots in the middle of the forewing. In good light and especially in fresh specimens the head of the Dun Skipper is golden brown.

Habitat:
Found in a variety of habitats including open upland habitats, and may be found nectaring in wetland areas. This species is more common along woodland edges and trails through woodlands in the northern part of the state

Overwintering Strategy:   Mid-stage Caterpillars

Flight:   
This species normally has a single brood that may be found from late June through late August.

Notes:   
The Dun Skipper is one of the most common skippers in Wisconsin and is found throughout the state. It seems more common in the northern part of the state, where it becomes abundant after the European Skippers abundance has waned.

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.
