Features
The moths have a wingspan of 22-24 millimeters ( 20 to 30 millimeters). The ground color of the forewings is slate gray, light gray to white gray. Two striking, wide lines cross the forewing. They are light brown, brown to black-brown. The inner transverse line is nearly straight, the outer transverse line bent with two outwardly facing spikes. When occurring in Central Europe subspecies ( ssp imbutata ) on the outside connects to the teeth of the outer transverse line to a brownish yellow to reddish-brown field. Root Windwärts and also in Saumfeld outside, another very fine transverse lines may be located. In some specimens the two lines can be connected in the rear half of the wing together by a "bridge". The fringes are alternately light and dark. From the Apex a Apikalstrich draws to reddish brown box.
Egg, caterpillar and chrysalis
The blunt- oval egg is initially whitish, later yellowish. The surface is covered with an irregular network pattern. The rosette of the micropyle shows eight leaves ..
The caterpillar is reddish yellow to brownish red and provided with a fine dark line of the back and side as thin ridge lines. The yellow side stripes are relatively wide and have red spots in the recesses of the middle segments. The spiracles are lined with yellow rings.
The slim doll is yellowish brown and has a reddish abdomen. The elytra have a forked appendage on ..
Geographical distribution and habitat
The species has a huge area, the Labrador (eastern Canada ) on the North American continent, northern Asia extends to the British Isles. In Northern Europe, the range extends to northern Russia and northern Fennoscandia, in the south to the Carpathian Mountains, Hungary and Transylvania, as well as to the Central Alps and the Swiss Jura.
She lives only in dwarf shrub rich bogs and peat bogs. In Baden- Württemberg the species is detected to about 1000 meters above sea level. In the Alps, they are found in the bogs of the Central Alps.
Way of life
The Cranberries release forms one generation per year; the moths fly from June to August. They are predominantly diurnal and crepuscular, but also come at night to the light. The caterpillar eats exclusively at Ordinary cranberry. They are found from April to the end of June / beginning of July to the food plants (Vaccinium oxycoccos ). The egg overwinters.
Systematics and Taxonomy
The species was described in 1813 by Jacob Hübner as Geometra sororiata first time scientifically. It is now assigned to the genus Carsia Hübner, 1825. Type species of this genus is Geometra imbutata Hübner, 1813, a taxon that is now regarded as a subspecies of Carsia sororiata. In the older literature the taxon is also known as Anaitis paludata Thunberg, 1788. Phalaena paludata Thunberg, 1788 is a junior homonym of Phalaena paludata Linnaeus, 1758 and thus invalid. Currently, the following subspecies are excreted:
- Carsia sororiata sororiata that Nominatunterart in Northern Europe
- Carsia sororiata imbutata ( Hübner, 1813), Central Europe
- Carsia sororiata anglica Prout, 1937, British Isles
- Carsia sororiata alpinata Packard, 1873, North America
- Carsia sororiata labradoriensis (Summer, 1897), Labrador
- Carsia sororiata thaxteri Swett, 1917, Newfoundland
- Carsia sororiata columbia McDunnough, 1939, North America
Endangering
The species is regarded in Germany as critically endangered (category 1).
