Brachionycha nubeculosa

Brachionycha nubeculosa, the Rannoch sprawler, is a moth of the family Noctuoidea. It is found across the Palearctic from the British Isles in the west, across central and northern Europe over Russia, Siberia to China. The species is only locally distributed in central Europe, but is often relatively common in this region. In southern Europe, the occurrence is limited to some mountainous regions. In Germany, it reaches as far as the summit regions of the low mountain ranges. The species is moisture loving and prefers moist, cool temperate forests, mixed forests, wooded valleys, river and stream edges as well as orchards. Source
