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.

Possible
About 20% of wildlife watchers report a Dun Skipper sighting in Congaree National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 145 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
August
In that month about 50% of wildlife watchers report a Dun Skipper in Congaree National Park on a given day, against under 5% in May–June and October–March, the lowest months.

GBIF citizen-science records
It is estimated from how often the Dun Skipper is recorded against all the insects logged in Congaree National Park (27 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
