features
butterfly
The relatively narrow forewings of the moths, which have a wingspan of about 26 to 32 millimeters, are dark brown in color and show an orange-yellow band in which there are two indistinct, small, white-pithed eye spots near the apex . Characteristic for the species are several small, pure white dots in the submarginal region of the hind wings, which are also responsible for the German name of the species. This distinctive marking makes the species unmistakable. A division into two parts can be seen on the underside of the forewings. While the outer field is colored yellow-brown, the middle and inner area shows a pale red-brown color. The undersides of the hind wings are unmarked brown in the males, gray-yellow in the females. Often the white spots shine through from the front, in the males stronger.
Egg, caterpillar
The egg is round and white. The caterpillars are light brown in their youth stage and have six fine, darker longitudinal lines; as adults they are coffee brown and show a dark brown, white-lined back line, fine secondary lines and broad side lines. The head is dark brown, the rear end is slightly tapered and ends in a short anal tip.
Synonyms
- Erebia arete (Fabricius, 1787)
distribution and habitat
The white-dotted black butterfly occurs in the Alps mostly at altitudes between 1600 and 1900 meters. It mostly lives in very small, narrowly defined habitats in the Austrian federal states of Salzburg , Carinthia and Styria . The species prefers to fly on southern slopes.
Way of life
The moths fly in July and August mainly in bushy meadow areas. Forage plants of the caterpillars are bristle grass ( Nardus stricta ), turf sedge ( Deschampsia cespitosa ) and common bluegrass ( Poa trvialis ).
Danger
