Adult: The ventral (lower) side is pure orange without markings; the fringe along the edge varies from orange to brown. The dorsal (top) side is similar in both males and females, with dark margins, black-lined veins, and a line at the end of the forewing cell. All markings in the female are wider, giving her a distinctive appearance. Females also have black at the base of the forewing. Males do not have a stigma (a black spot on the top of the forewing that produces pheromones to attract females).
As a grass skipper, this species commonly rests with the forewings held open in a V shape while the hindwings are held out horizontally to the side. It may also have all four folded together so that only the bottom surfaces are visible.
Larvae are bluish-white with black dots and a crescent-shaped bar at the rear. The head is white with black bands and lines.
