The Blue-eyed Grayling ( Minois dryas ), also blue core print , is a butterfly ( butterfly ) from the family of Nymphalidae (Nymphalidae). The specific epithet is derived from the dryads (forest nymphs ) from Greek mythology .
features
The moths reach a wingspan of 45 to 60 millimeters. The upper side of the wing is dark brown, slightly shimmering black-blue and has two small black eye-spots with a light blue core on each fore wing, of which the outside is slightly smaller than the inside. These spots are much smaller in the male than in the female. On the upper side of the hind wings there is another, much smaller eye spot. The underside of the wing is gray-brown in color and has the same eye-spots on the forewings as can be found on the upper side. The spot on the hind wings may be missing on the underside. A pale gray band over the fore and hind wings can just be seen.
The caterpillars are about 30 millimeters long. They are broadly light brown and white striped lengthways in different color levels. In addition, the colors are finely marbled. A dark brown longitudinal stripe runs along the back, which is indistinct at all segment boundaries. On the sides, over the stigmas, there is a continuous vertical stripe of the same color. Between the two dark stripes, a fine, indistinct dark line is surrounded by light, wide vertical stripes. The head capsule is light brown and has 6 dark, noticeable longitudinal stripes. There are two semicircular appendages next to the mandibles .
Occurrence
The animals mostly live in damp, rarely in dry, open areas such as B. on litter meadows near moors or on dry grassland . They have become very rare and occur in Central Europe in the east of Northern Germany , on the Kyffhäuser , in Northern Bavaria on the Upper Rhine and especially in the Alpine foothills .
Flight and caterpillar times
The blue-eyed forest porter flies in one generation from July to September. The young caterpillars can be found from September, they overwinter and can be observed until June the following year.
Way of life
The moths are typical inhabitants of different biotopes. These are species that can inhabit several different biotopes and live in them like biotope inhabitants. The blue-eyed forest porter occurs in both dry and wet areas. Often found sunbathing with wings wide open; this is atypical for butterflies.
Food of the caterpillars
The caterpillars feed on various sweet grasses , but above all pipe grass ( Molinia caerulea ), land riding grass ( Calamagrostis epigeios ) and upright brusque ( Bromus erectus ).
development
The females drop their eggs on the ground near the forage plants. The caterpillars overwinter before the first molt. The caterpillar digs a shallow pit on the ground for pupation. To do this, it uses its semicircular appendages next to the mandibles.
