The arctic skipper is a member of the skipperling subfamily, Heteropterinae. They are a circumpolar species that is usually found in the north. The arctic skipper overwinters in its larval, or caterpillar form. They form a chrysalis that looks like faded glass in the spring and usually are on the wing in mid May to early June, with typically only one brood per year. Caterpillars typically feed on a variety of grasses while the adults prefer wild iris, bog laurel and Labrador tea.
