The almost square field between the ring and kidney flaws is conspicuously black-brown, as are the inner and outer borders of the same. The inner third and the extension of the tenon flaws towards the edge are also colored. There are other smaller dark spots on the Costa . The wavy line is yellowish and strongly wavy. On the inside there are individual arrow marks in the upper part. The seam area has a slightly darkened tint. The hind wings are unmarked and monochrome gray-brown. The lighter colored individual form f. dissoluta Stgr. has lighter hind wings, ash-gray forewings with strongly protruding black markings and more sharply contoured and lighter transverse lines, while the mainly in Turkey flying and earlier than ssp. subdissoluta Wagner is extremely dark brown in color. The ssp. Found in the Pyrenees as well as in Spain and Morocco . andreae Dufay is drawn smaller and less contrasty.

Caterpillar, pupa

The caterpillar is yellow-brown in color, has a thin, pale, white-yellow, dark-lined back line as well as indistinct side back lines with dark diagonal stripes in between. The light side stripe is wide and has black-brown stigmas embedded in it . The slender, red-brown doll has two short thorns on the cremaster .

Geographical distribution and habitat

The brown lab-cabbage owl is common in Europe and can be common in very limited places. In the mountains it can still be found at heights of over 2000 meters. The species is also found in Morocco , Turkey , Armenia , Syria , Iran , Lebanon , Israel, and the Caucasus . The species is mainly found in warm, mountainous areas with limestone soil .

Way of life

The brown lab-owl forms one generation per year, the moths of which fly from mid-June to mid-August. The moths are mostly diurnal and prefer to fly in the sunshine. They like to rest on the flowers of various plants. But it also occasionally comes across artificial light sources . The caterpillars live on bedstraw species ( Galium ) from September , mainly on meadow bedstraw ( Galium mollugo ). They hide during the day and usually feed at night. They overwinter and pupate mostly in May of the following year.

Danger

The species is very rare or completely absent in many northern regions and is listed in Germany in Category 2 (severely endangered) on the Red List of Endangered Species . In Austria , too , it is considered a rare, severe regression type.

Systematics

Fibiger (1990) synonymizes most subspecies and forms with the nominate form; he only recognizes a subspecies in addition to the nominate form.

  • Chersotis multangula multangula (Hübner, 1803), wingspan 32 to 36 mm,
  • Chersotis multangula andreae Dufay, 1973, wingspan 28 to 32 mm, Pyrenees, Spain and Morocco
