Life History
Poorly known. There is a single brood each year, and the adults are nocturnal and come to light. The adults fly in late summer so the wintering stage must be the egg or early instar larvae.
Conservation
A common widespread species; no concerns.
Diet Info
No Alberta data; elsewhere reported to use Pedicularis canadensis, Galium, Vaccinium sp., etc. (Handfield, 1999).
Range
Nova Scotia to British Columbia, south in the mountains east and west. In Alberta found throughout the grasslands and parklands region, as well as in the lower foothills and southern boreal forest.
