Euphyes vestris, commonly referred to as the dun skipper, is a butterfly belonging to the Hesperiidae family. It appears as a brown, medium-sized butterfly found across the United States and southern Canada. Euphyes vestris inhabits multiple environments, including open fields, oak woodlands, and riparian wetlands. There are currently four recorded subspecies of Euphyes vestris, three of which have been identified across eatern, western, and mountainous regions of North America. The fourth subspecies, Euphyes vestris harbisoni, known as the Harbison's dun skipper is geographically restricted to southern California and northern Mexico.
The dun skipper, Euphyes vestris, is categorized within the genus Euphyes, a known group of ten closely related skippers found in North America. Species belonging to this genus live in environments with high humidity, such as swampy habitats, and occur in small populations. Across its subspecies it has been recognized that E. vestris relies on sedges, which are plants in the family Cyperaceae, as host plants for its larval development.
