The moths reach a wingspan of 32-40 millimeters. You have dark brown upper wing in three to five yellow, different sized ocelli can be found in black and in white core on each wing. The ocelli are separated from each other, but are sometimes very close to each other. The lower wing is the same as the upper surface of dyed. The ocelli are very variable in their appearance and number. Falter who live at higher altitudes with them usually much narrower yellow borders.
The caterpillars are about 20 mm long. They are light beige or light green and have a dark, whitish on the sides of the back. On the sides of the animals you can see several very fine, dark longitudinal lines.

Occurrence
They come from France to over Central and Eastern Europe and especially in the South and Central German Uplands and the Alps often. In the north German lowlands they are almost extinct. They particularly live on sunny forest edges, clearings and meadows, on verbuschtem dry grasslands on mountain and fen meadows but also in peripheral areas of bogs and wet meadows. They are found up to an altitude of 2,300 meters. In Austria occurring in the Alps, has become rare in the foothills.
Flight times and caterpillars
The moths fly from mid-May to mid-July in one generation. The species is so far the first Central European ringlet, which occur in the year. At higher elevations they occur from mid-June. The caterpillars are found from July to April.
Way of life
The females lay their eggs singly or in small groups on blades of grass. The caterpillars feed on the leaves of Upright Brome ( Bromus erectus ), skipjack or sheep fescue ( Festuca ovina ) and other grasses. The caterpillars overwinter almost fully grown and pupate until the following spring in loosely spun blades of grass on the floor in a doll's chamber. Herein is light - beige, on the wing buds and the abdomen segments black striped doll upright. Sometimes it happens that the caterpillar overwinters twice before they pupate. The moths are often found on flowers of thistles and Dost sitting. In total there is about the food of the moth and the caterpillar is still relatively little known.
