It is found in North America from eastern Quebec, through northern Ontario (south to Sudbury), and the northern Prairies to northern British Columbia, the Northwest Territories, Yukon, and Alaska. It reaches just into the northern U.S. between Michigan and Montana, and also occurs in Asia, where it has been recorded from the Chukot Peninsula to the eastern Sayan Mountains and Amur. The habitat consists of large, open, grassy bogs and other areas with acidic soils. The wingspan is 35–44 mm. The wings are brownish black without eyespots. The forewings have a large chestnut-red patch both above and below. The underside of the hindwings is mottled grey and brown.[2] Adults are on wing from May to late July depending on location.[3] The larvae feed on Eriophorum species. Subspecies
