The Dun Skipper is dark purplish brown, and a wing span of 2.3 to 2.7 cm. The male has no significant markings except for the black stigma; the female has a series of small white spots on her forewing’s upper and under sides, the underside spots are slightly smaller, and a faint pale-purplish crescent on the hindwing underside.

In the Algonquin Highlands you will find these butterflies on flowers, mostly on white, pink, and purple ones, along roadsides and in open, moist areas. They fly from late June to mid-August.

Females lay light green eggs singly on the leaves of a variety of sedges. The eggs change to a red colour before hatching. The larva is pale green and patterned with white and ringed with a thin black stripe; its cream-coloured head has a black spot in front and a brown stripe on each side.
