Features
The wingspan of the butterfly is 39 to 45 millimeters. The color of the forewings varies from light brown to dark brown to reddish brown. Cross lines and blemishes (ring and kidney blemish ) are usually clearly marked. The flaws are outlined usually somewhat darker and often white. The transverse lines may be lighter or darker than the base color. Often darker transverse lines are bright margins. The hind wings are yellow with a black border union band. The black, crescent-shaped Diskalfleck is clearly drawn. The early stages are known insufficiently.
The egg is hemispherical with flattened base. It measures 0.5 to 0.5 mm in height and 0.6 to 0.7 mm in diameter. The surface has at the top two-thirds of about 30 wide and clear longitudinal ribs that intersect with weaker transverse ribs. But most of the cross- ribs do not reach the Mikropylregion.
The bead should be " lively " colored than the caterpillar of Noctua Orbona.
Similar Species
Noctua interposita distinguished by the following features Noctua Orbona: The mean transverse line is created to know their start at Costalrand, the Costalfleck at the end of the shaft line is dark brown, not deep black and not sharply limited to the wing the base. Click on the yellow hind wings the dark edge binding and the crescent- shaped central spot are slightly wider. At Noctua comes missing this spot or only diffuse light to dark brown. Usually cross lines and blemishes with Noctua interposita are more clearly developed than Noctua Orbona and Noctua comes. Clearly can be the species differ by a genital examination.
Geographical distribution and habitat
The fact that the species was only (re) recognized relatively late as an independent type, the distribution area is known insufficiently. After Fibiger that species have a Mediterranean-Asian spread. It is proven safe in South, Central Europe and Southeastern Europe, but usually only patchily. But you seem to be missing in the British Isles. To the east and southeast includes the distribution area of Turkey, the Caucasus, Armenia, Southern Russia and the European part of Kazakhstan and Western Siberia. The species is known as a migrant butterfly; it is therefore also reported repeatedly from Sweden and from Finland.
The preferred habitat is steppe, dry forest margins, warm slopes and river valleys.
Way of life
Noctua interposita is one generation per year, the butterflies fly in from warmer regions May to September infrequently until well into October. Depending on the region keep the moths a different long summer rest. The moths are nocturnal and come to artificial light sources. Visit flowers and can be baited. The caterpillars can be found in August. They overwinter and pupate mainly in April of the following year. They feed on the leaves of various herbaceous plants and grasses.
Endangering
Since Noctua interposita is not yet long been known as a distinct species and can be easily confused with other species, the spread in Germany is still insufficiently documented. On the red list of endangered species it is (assuming risk, but status unknown) in the category G rated.
