The alpine and subalpine.
Late August in Alberta, June to August elsewhere (Razowski 1979).
The forewing varies from pale white to reddish brown but is most commonly light yellow. A brown line is normally prominent from the middle of the costa to the anal angle and a similarly coloured small mark near the apex. A small basal dark marking and reticulations throughout the forewing are also occasionally present. The hindwing is usually off-white, but can occasionally be grey.
The larva feeds upon Subalpine Larkspur (Delphinium barbeyi) in Alaska. (Razowski 2002)
