features

butterfly

The wingspan of the moth is 32 to 37 millimeters. The upper side of the forewings is dark brown to black-brown, the submarginal region whitish, sometimes also darkened gray-brown. An ocher-colored, sometimes light pink line extends from the root over the inner edge and including the outer transverse line. The blemishes are reduced to indistinct black spots. A large, dark shadow can be seen below the very pointed apex . The hind wings are gray-brown without drawing. The proboscis of the moths is well developed. The long palps are stretched out like a beak.

Caterpillar

Adult caterpillars are greenish in color. They are slim, 14-footed and show clearly separated segments. The segment incisions are yellow. The green head, brown on the sides, is dotted with black. Individual hairs protrude from the black point warts.

distribution and habitat

The blueberry beaked owl is widespread in Central Europe. To the east the distribution area extends to Armenia . In the Alps it rises to altitudes of 1,800 meters. The animals are preferably found in coniferous and mixed forests as well as in raised and heather bogs.

Way of life

The crepuscular and nocturnal moths fly in one generation between May and September and are sometimes scared away from the vegetation during the day. They visit bait and artificial light sources at night . The leaves of the bilberry ( Vaccinium myrtillus ) are the main food of the caterpillars . Occasionally they have also been observed on bog berries ( Vaccinium uliginosum ) or heather ( Erica ). The species overwinters either as an adult caterpillar or as a pupa.
