Features
Butterfly
The wingspan of the butterfly is 28 to 36 millimeters, the color of the forewings varies from slate and silver gray on gray brown to blue-gray or purple -gray. First and foremost, climatic or geological factors for the color configuration are responsible. Kidney and ring stain are large, often significantly light gray, partially filled gray brown and framed by a dark midfield. At the root of a short black Basalstrich be seen. From the wavy line extending outward to hem a slightly darkened area. The ring stain have a distinctive, slightly obliquely positioned, elliptical shape, resulting in the Grey Bergraseneule can be well distinguished from standard drawing and color similar species. In the males, the hind wings are solid light gray-brown, with the females slightly darker. The veins are easily visible.
Caterpillar, and chrysalis
The caterpillars are dull brown in color, have a fine, whitish dorsal line, which emerges clearly only the first segments and indistinct, bright side back lines that are limited dark down. Striking are the black spiracles and the light brown head. The doll is in the middle of the back segments each have a recess. At the cremaster are eight fan-like bristles positioned.

- Dry grassland Blättereule ( Pachetra sagittigera )
- Arrow Patch Kräutereule ( Lacanobia contigua )
- Zahneule ( Hada plebeja )
- Lasionycta orientalis ( Alphéraky, 1882). These sister species has been confused with the proximal long in Central Asia, but preferably mountainous steppe areas, which the animals can be distinguished most likely due to the locality.
Geographical distribution and habitat
The distribution of the species extends from Spain patchy across Europe and further east to East Asia ( Amur region ). You lack in the northwest of the British Isles. In the north, the incidence ranges to near the Arctic Circle, to the south by the Mediterranean to the Caucasus and Mongolia. In the Alps, it rises to around 2500 meters altitude. The Grey Bergraseneule is by Bergmann indicator species of open grassland herb of rocky, warm Halden crippled, lights bushes vegetation in valley meadows of the lower mountain zone. However, in Baden-Württemberg it is more likely in montane fir and spruce forests and upper montane Nardus grassland areas ( Nardetum strictae ) and prior to dry forest edges.
Way of life
The Grey Bergraseneule is univoltine; that is, It is usually formed only one generation. The moths of this generation fly from June to August. In the Southern Alps, a second generation should set their butterflies fly in October. The moths are mostly nocturnal, but during the day occasionally found in the Alps in flower at dusk for example, on thistles, knapweed (Centaurea ), and agrimony ( Eupatorium ). They appear at night with artificial light sources, rarely also on KödernDie caterpillars live mainly in August. They feed at night on the leaves of various plants. These include Spitzlappiger lady's mantle ( Alchemilla vulgaris), Dandelion (Taraxacum ) and sagebrush species ( Artemisia ). When breeding they also frills dock ( Rumex crispus ) and garden bellflower (Campanula ) on. The caterpillars overwinter and pupate in May or June of the following year.
Endangering
The Grey Bergraseneule is common in many regions of Germany and not there at risk, in North Rhine -Westphalia and Lower Saxony, however, rare and therefore there on the red list of endangered species in Category 2 ( high risk ) classified.
