features

butterfly

The wingspan of the moth is on average 19 to 21 millimeters. The basic color of the forewings varies from white-gray to light-gray to green-gray. The forewings show an alternation of different colored bandages. A typical wing drawing consists of the following color sequence: The basal region is dark brown and is bordered by a narrow light band. The disk region is brown or dark gray, can vary in width and shows a black center and a jagged bulge along the edge. The post-fiscal region is light brown. This is followed by the dark brown submarginal area , from which a white wavy line stands out. The individual bandages usually begin very clearly at the front edge and weaken slightly towards the rear edge. The posterior wings, which are not marked, have a silky white sheen.

Caterpillar

Adult caterpillars are yellow-green in color, have dark back and side back lines and wide light green side stripes. These are reddish in the middle and whitish at the top.

Doll

The yellow-green pupa shows dark wing sheaths. There are two thorns on the cremaster .

Geographical distribution and occurrence

Perizoma incultaria can be found in the entire Alpine region up to the Carpathians and the mountains of the Balkan Peninsula . In the Alps, the species occurs at altitudes between 1200 and 2300 meters. It prefers to inhabit barren mountain and mountain landscapes as well as alpine meadows.

Way of life

The moths fly in one generation from May to August, sometimes during the day and suckle in damp places. At night they also visit artificial light sources . The caterpillars feed on the seed heads of various Primrose - ( Primula ), Bartsia - and saxifrage species ( Saxifraga ) or minieren on its leaves. The fully grown caterpillars pupate in a light web on the ground. The species overwinters as a pupa.

Danger

Perizoma incultaria occurs in large numbers in Germany in the Bavarian Alps and is not endangered there. An older reference to an occurrence in Baden-Württemberg is certainly based on a mix-up or a wrong determination.
