The wingspan of the butterfly is 48 to 60 millimeters. Front and rear wings have on the top of a light brown to reddish-brown color. In the Submarginalregion forewing top two to three black ocelli take off. The top of the rear wing is provided with one or two black eyespots near the Analwinkel. All ocelli are surrounded more or less orange, which can be the butterflies well distinguished from other Oeneis species. The undersides of the forewings are yellow -brown, the eye-spots of the upper side shine through. The hind wing underside is mottled black-gray to blackish brown.
The ball-shaped eggs are initially green yellow and discolor soon in brownish hues. On the entire surface is a polymer formed from many whitish, strongly serrated longitudinal lines stripe pattern.
Full-grown caterpillars are brownish, ocher or greenish colored and provided with red-brown side lines and stripes. The body is very short brown haired and slightly forked at the end.
The yellowish doll shows lots of brown spots and heavily darkened wing sheaths.

Way of life
The moths fly in one generation, depending on the region May to August. Occasionally they suck nectar of flowers. They like to rest with folded wings on tree trunks and are therefore to predators difficult to detect. As a food plant of the caterpillars several Sedge family ( Cyperaceae ) such as Eriophorum be spissum called Carex Carex concinna and geyeri. As the type predominantly occurs in regions with only short periods of heat and nutrient-poor vegetation, it takes two years to develop. The caterpillars overwinter first in first, second or third, and for the second time in the fourth, fifth or sixth instar.
