Adult Food: Nectar from flowers of low-growing plants including blueberry, wild strawberry, and Canadian cinquefoil.
Habitat: Open areas near woods including valley bottoms, barrens, meadows, grassy hillsides, tundra, scrub oak openings.
Range: Holarctic. In North America, from Alaska south and east to central Ontario and northern Michigan. Isolated populations in Labrador and arctic Quebec, the central Appalachians, and the Rocky Mountains from central Alberta south to northern New Mexico.
Conservation: Populations on eastern shale barrens (subspecies wyandot) should be monitored and conserved.
