The Arctic skipper has a wingspan of 1 to 1.25 inches (2.5-3.3 cm). The uppersides of its wings are dark brown with large orange spots and patches. The underside of its wings is tan to dark brown with white to cream colored spots edged in dark brown.
The Arctic skipper caterpillar eats a variety of grasses, including purple reedgrass. The adult Arctic skipper eats nectar from flowers, including wild iris and Jacob’s ladder.
The female Arctic skipper lays single eggs on the leaves of a host grass plant from May to July. The eggs hatch in around 10 days. The larvae bind together leaves from the host plant with silk to make a shelter.
The Arctic skipper overwinters encased in its leaf home. When it emerges in the spring, it may rest for up to a week before it begins pupating. It emerges as a butterfly 5-6 weeks after pupating.
