scientific name    Dasylophia anguina    

common name     Black-spotted Prominent

Arid native grassland and badlands in the valleys of the plains.

Adults have been captured in late June and July.

A medium-sized (3.0-4.1 cm. wingspan) relatively long-winged moth. Forewings dark grey-brown with horizontal black streaking in the male, shaded with yellow-brown in the female. There is a small pale patch with a black pupil marking the lower edge of the reniform. The lower part of postmedian line is sharp and rounded, with a black oval spot often joined with a second smaller one above, in the terminal area near anal angle. Male hindwings pale, slightly darker near outer edge; dark grey in the female. Male antennae bipectinate for about 2/3 of the length and then simple for the remainder. Female antennae are simple.

life history
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.

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).

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.
