The gray lab -owl ( Chersotis margaritacea ), also known as the light rock-grass earth owl or pearl earth owl , is a butterfly ( moth ) from the owl butterfly family (Noctuidae).
features
butterfly
The wingspan of the moth is about 34 to 40 millimeters. The fore wing color is ash gray. The thorax is light gray, the head whitish. At the costal edge between the ring and kidney flaws there is an almost square black-brown spot that is occasionally slightly notched from below, as well as three other, smaller, dark spots on the costal edge. The blemishes and cross lines are indistinct. There is often a small black point in the cone flaw. The drawing can go out on some copies except for the black spot between the blemishes. The fringing area is a little darker gray, with a brownish tinted, washed-out region near the wing tip. The hind wings of the male butterflies are mostly snow-white, with short, thin, silky hair fringes. The hind wings of the females are gray-white.
Egg, caterpillar, pupa
The egg is gray-green with reddish spots on the pole and an equally colored band in the middle. The young caterpillar is gray-brown to yellow-brown in color and has light longitudinal lines, the older caterpillar develops additional dark, wedge-shaped oblique spots on the sides. Spot-like darkening can be seen in the segment incisions. The doll is colored reddish brown and has two short thorns on the cremaster .
Similar species
The species is similar to the gray late summer ground owl ( Eugnorisma glareosa ), which, however, has several more pronounced signs on the costal edge.
Geographical distribution and habitat
The species is distributed throughout southern Europe and in Central Europe to northern Belgium, the northern edge of the low mountain range, south-eastern Poland, the Ukraine (Crimea) and the northern Caucasus. It also occurs in North Africa ( Algeria , Morocco ), Asia Minor , Lebanon , Israel , Iran , Georgia , Armenia , Kazakhstan and as far as the Altai .
It is mainly found in warm areas with limestone soil and inhabits sunny slopes and scree slopes, among other things. In Spain it was found up to 1580 meters above sea level.
Way of life
The gray lab-eared owl forms one generation per year, whose moths fly from late June to early September. They are nocturnal and come to artificial light sources and visit the bait . The caterpillars live on bedstraw species ( Galium ) or Hill-Meier ( Asperula cynanchica ) from September . They usually feed at night, overwinter and pupate by May of the following year.
Danger
The species is very rare or completely absent in many northern regions and is listed in Category 3 (endangered) on the Red List of Threatened Species in Germany, and on the warning list in Baden-Württemberg.
Systematics
There are three subspecies:
- Chersotis margaritacea margaritacea (Villers, 1789)
- Chersotis margaritacea atlanticola swing shot, 1955, Morocco and Algeria
- Chersotis margaritacea orophila Rungs, 1967, Morocco and Algeria
The status as a subspecies has yet to be confirmed. Most of the other subspecies and varieties were reunited with the nominate subspecies by Fibiger (1993). Conversely, the earlier subspecies cyrnea Spuler turned out to be an independent species from Corsica in 1908.
