features
butterfly
The wingspan of the moth is 38 to 44 millimeters. The forewings are maroon or reddish brown in the basic color and relatively unmarked. The costal edge has a wide, straight, cream-white stripe from the root to about the level of the slightly light-edged kidney blemishes . This flows into one another with the ring flaw and forms a kind of tooth. The kidney flaw is outlined in cream color. There is a short, black root line. The hind wings of musiva are whitish with a light brown margin and clearly protruding veins.
Egg, caterpillar, pupa
The egg is hemispherical, colored white and strongly ribbed towards the pole. The caterpillar is dirty reddish-yellow to yellowish-brown, with dark longitudinal bands and diagonal stripes, light topline and weakly developed secondary dorsal lines. The doll is red-brown and has two pointed thorns on the cremaster .
Similar species
- Light-edged earth owl ( Ochropleura plecta (Linnaeus, 1761)) is significantly smaller with a wingspan of 28 to 34 mm
- Ochropleura leucogaster Freyer, 1831, is also smaller on average with a wingspan of 32 to 36 mm
Geographical distribution and habitat
The species occurs locally in some mountainous parts of Europe, Turkey, Armenia, the Caucasus, Turkestan , Asia Minor, southern parts of Siberia, Mongolia, Tibet, and western China. It prefers hilly and mountainous, dry terrain up to an altitude of about 2500 meters.
Way of life
The moths are mainly nocturnal, fly from June to September and visit Osthelder in the Alps to see the flowers of pigeon goiter ( Silene vulgaris ), as well as bait and artificial light sources . The caterpillars can be found polyphagous on herbaceous plants from September, for example on common chicory ( Cichorium intybus ), meadow bedstraw ( Galium mollugo ), as well as on wire-haired rock cress ( Arabis hirsuta ) and dandelion ( Taraxacum ). They overwinter and pupate mostly in April.
Danger
In Germany, the alpine matte earth owl is only found in a few places in Bavaria, is extremely rare and is classified on the Red List of Endangered Species as a species with geographical restriction (category R). In Baden-Württemberg, Albocosta musiva occurred on the Swabian Alb until the 1930s, after which it became extinct for unknown reasons. Occasionally she is found north of the Alps as an immigrant.
