The red-brown grass owl ( Mythimna turca ), sometimes also called marbel owl, is a butterfly ( moth ) from the family of the owl butterflies (Noctuidae).
description
butterfly
The wingspan of the moth is 34 to 46 millimeters. In terms of their size, they are sometimes considerably larger than other Mythimna species. The color of the upper side of the forewing varies from red-brown to rust-brown or red-gray to ocher. Two distinct, black-brown transverse lines are typical of the species. The kidney flaw is bordered in white and dark, and there are no tenon and ring flaws. There is a row of small black arrow marks along the hemline. The undersized upper side of the rear wing is dark gray-brown, only the edge and the fringes are reddish.
Caterpillar
Adult caterpillars have a reddish brown basic color, the ventral side is lighter. They show a thin, interrupted, light, dark edged back line as well as thin, dark, slightly jagged side back lines.
Doll
On the cremaster of the dark brown doll there are two long spines curved at the end.
distribution and habitat
The red-brown grass owl is widespread in Central Europe. The eastern extension extends through northern and central Asia to northern China , Korea and Japan . The species mainly inhabits bog and quarry forests, damp meadows and forest clearings as well as raised bog areas. In the Alps it rises to a height of around 700 meters.
Way of life
The moths fly in one generation in the northern range, in two generations in the south and are found between June and August. They are nocturnal, fly to artificial light sources , visit bait and have also been observed sucking on unspecified thistles and flutter rush ( Juncus effusus ). Various sweet grasses (Poaceae) as well as trembling grass sedge ( Carex brizoides ), rough sedge ( Carex hirta ) and chickweed ( Stellaria holostea ) are named as food plants for caterpillars . The species overwinters as a young caterpillar.
Danger
The red-brown grass owl occurs in all German federal states, but is in some cases in decline and is therefore included in the red list of endangered species on the "warning list".
