Features
Butterfly
The wingspan of the moth is about 25 to 28 millimeters. The forewings are dark brown to gray-black staining. The square box between the ring and kidney blemish is deep black, as well as some small stains on Costalrand. Ring and kidney stigma are yellow brown and stand out clearly. The kidneys blemish is extended in the direction of ring flaw in the Shape of a L. The inner field of the journal blemish has a dark brown color and a yellow-brown border. The midfield is tinted dark brown, intersected by some bright veins and also limited by light transverse lines. The wavy line is jagged, somewhat lightened the narrow outermost Saumfeld. Body and hind wings are uniformly dark brown.
Egg, caterpillar, pupa
The egg is yellowish-white, spherical, flattened at the base and has some fine ribs. The caterpillar is dark earth brown color, has a bright back line that is extended diamond-shaped on each segment and two adjoining ridge lines that are limited brown the top. The slim, light brown doll has two very short, hook-like thorns on the cremaster.
Similar Species
Similar types are:
- Chersotis alpestris ( Boisduval, 1837), slightly larger, breitflügeliger and more brightly colored.
- Chersotis transiens (Staudinger, 1897), first set up as a variety of Agrotis ocellina, she was recognized in 1954 by Charles Boursin as an independent species. The color of forewings and thorax dark red-brown. It is located mainly in the Russian- Asian region, it does not come together before with Chersotis ocellina and can therefore be distinguished on the basis of certain locality.
- Chersotis Oreina Dufay, 1984, occurs partly in the same habitat as Chersotis ocellina. It has a dark brown ground color of the fore wings with very distinctive drawings.
A reliable differentiation of all the above types can only be performed by specialists or by a genital examination.
Geographical distribution and habitat
Chersotis ocellina occurs in Europe in hilly or mountainous areas, especially in the Alps at altitudes of 1500-2500 meters and in the Apennines, the Pyrenees and the Cantabrian mountains. For the population in the Pyrenees REZBANYAI - Reser has the subspecies Chersotis ocellina pyrenaellina erected in 1999. Older information about discoveries in Baden- Württemberg proved in retrospect to be misidentifications or could not be confirmed by copies. Recently, the species has been reported but from Daghestan (Russia). This would expand the distribution area very far to the east or would be completely isolated from the present area of distribution. A confirmation is not yet available; it could also be an occurrence of Chersotis transiens whose distribution area extends at least into the Southern Urals, so is much closer geographically. Fibiger also mentions an earlier detection of Chersotis alpestris from the southeastern part of European Russia, which is probably is Chersotis transiens.
The species is mainly found in open, rocky areas and alpine meadows.
Way of life
Chersotis ocellina is univoltine, meaning it only one generation per year will be created. The moths fly in July and August. They are predominantly diurnal, fly preferably in the sunshine and love to visit flowers of various plants. However, they are also numerous in artificial light sources and the bait. The caterpillars feed on low herbaceous plants. The caterpillars also hibernate.
Endangering
The species occurs in Germany only secured in Bavaria before, there is area as numerous and will not be classified on the Red List of endangered species in this state as endangered.
