Brachionycha nubeculosa

The Rannoch sprawler (Brachionycha nubeculosa) 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.

Hindwings whitish fuscous, with dark fuscous discal spot and terminal dots. Larva pale yellow-green deeper laterally ; tubercular dots pale yellow ; an oblique lateral streak on 4, and transverse streak on 12 yellow; legs more or less red. The larva habitually rests with the anterior segments strongly thrown back over the body, and the legs outspread.[1]

The moth flies from March to April .

The larvae feed on birch, willow, Populus tremula, Prunus padus, Lonicera xylosteum, Tilia, Rhamnus frangula and Aster species.
