Adults are nocturnal and come to light. There is apparently a single brood. Unlike most members of the family, which feed on trees and woody shrubs, the Black-spotted Prominent will use herbs in the Pea family, and in Alberta can be found in areas devoid of trees or shrubs.
Conservation
Alberta is at the northern edge of the range of anguina, and here it is rarely encountered.
Diet Info
No Alberta data; elsewhere reported to use legumes including clovers (Trifolium sp.), Lespedeza, locust, and wild indigo (Baptesia).
Range
From the Atlantic west to the Rocky Mountains, south to Florida, Texas and Colorado. In Alberta it has been collected in the southern part of the province, from Lost River to Lethbridge.
