Dun Skipper (Euphyes vestris) is a small butterfly (wingspan 23â32 mm) with uniform chocolate-brown wings with a purplish hue and tan fringes on the outer margins. Adults sit with their hindwings laid flat and their forewings held upright. The head and thorax of adults (both sexes) are yellowish-orange. Eggs are pale green, crescent-shaped, globular, and smooth when first laid, but prior to hatching the top of the egg changes to a reddish colour. Larvae have a shiny, pale green body with many fine and wavy silvery lines. Pupae are various shades of yellow, brown, and light green, with a blunt, ridged edge at one end.
Dun Skipper was designated as Threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 2001. The reasons for this assessment were that the western population of Dun Skipper (vestris subspecies) occurs in a restricted area. It has all but disappeared from Vancouver Island and its continued survival on the island is doubtful. Although the mainland population is limited by the availability of suitable habitat, populations at some locations are relatively secure. The butterfly is listed as Threatened in Canada on Schedule 1 of the Species at Risk Act (SARA). In British Columbia, Dun Skipper is ranked S3 (special concern, vulnerable to extirpation or extinction) by the Conservation Data Centre and is on the provincial Blue list. The B.C. Conservation Framework ranks Dun Skipper as a priority 2 under goal 2 (prevent species and ecosystems from becoming at risk). Recovery is considered to be biologically and technically feasible...
The population and distribution goal is to maintain current populations for Dun Skipper throughout the species natural range and distribution in British Columbia.
