Features
Butterfly
The front wings have a wingspan of about 28 to 36 millimeters. They are dark brown in color and vary in the distinctness of the eye spots. The somewhat brighter -colored females show strong trained eye spots, both on the front and on the hind wings. In most butterflies is in the Postdiskalregion the forewing a short red-brown tie with two arranged very close to each other, distinct eyespots, which may also be referred to as a double eye and so led to the German name of the species. The underwings are almost without markings dark brown to yellowish brown and very clearly show translucent white -centered ocelli.
Egg, caterpillar, pupa
The egg is provided by shiny off-white, with weak ribs. In the adult caterpillar is dominated by a lehmgelber color, interrupted by narrow, violet-brown back stripe and well colored wider foot patrols. On the yellowish tinted doll, the dark veined leaf sheaths are distinctly.
Similar Species
A certain similarity to the round eye ringlet ( Erebia medusa ), but at OeME are the insides of the sensor piston black, while they have at medusa a reddish brown tint.
Distribution and habitat
The double eye ringlet occurs in the Alps, the Pyrenees, the Velebit, the Rhodope Mountains and the Carpathians, mostly 900-2000 meters before. It prefers wet meadows, mountain bogs and wet clearings.
Way of life
The moths fly in one generation from June to August. Main food plants of the caterpillars are different grasses, such as:
- Alpine bluegrass ( Poa alpina)
- Kentucky bluegrass ( Poa pratensis)
- Grove bluegrass ( Poa nemoralis )
- Ordinary red fescue ( Festuca rubra)
- Blue-green sedge ( Carex flacca )
- Horst- sedge ( Carex sempervirens)
- Vile dithering grass ( Briza media )
- Purple moor grass ( Molinia caerula ).
In the high mountains the way lived through a two year development cycle.
Endangering
In Germany the species is found only in the Bavarian Alps, where it is locally numerous. However, it is out on the red list of endangered species on the early warning list.
