A member of the Satyrinae subfamily, C. pegala 's common name is misleading as it mostly occurs in fields and open areas. Eastern Canadian subspecies is nephele.

Identification: Males are dark brown, females slightly lighter in color and larger. Prominent eye-spots with white pupils on both top and bottom forewings. Upper hindwing may have up to three eyespots and the underside up to six. As with other Cercyonis species, the outer edges of the hindwings are markedly scalloped. Wingspan: 39-44 mm.

Life History: One brood. Hibernates as a newly-hatched caterpillar. Larvae are green with a dark green stripe on the back, two pale lateral stripes, and two reddish tails. Adults are weak fliers and can often be flushed up in disturbed fields and native grasslands. They can often be seen puddling and nectaring on flowers.

Habitat and Range: Open flowery meadows, old fields, and roadsides. It is common in the southern parts of the province and in the Ottawa District. It is found north to Lake Abitibi, the north shore of Lake Superior and Lake of the Woods. In Canada it is found in every province except Newfoundland.

Host Plants: Larvae feed on grasses such as Wild Oats (Avena fatua), Purpletop Grass (Tridens flavus), and bluestem (Andropogon spp.) Adults get nectar from thistles and Alfalfa (Medicago sativa).

Flight Period: Late June to early September
