Features
The moths reach a wingspan 34-42 Millimetern.Kopf and thorax are light green in color and fitted with black spots on patagium and tegulae. The ground color of the forewings is celadon green. These are equipped with black spots, which are concentrated in the range of Basallinie, medium shade and wavy line and the transverse lines trace. The wavy line is continuously developed in most specimens, and lined dark green on the outside. The inner and outer transverse line, however, are only indicated by single, irregular points. The kidneys and ring stain are well developed and usually black in color. The hind wings are gray and darker towards, with an indistinct transverse line and clear Diskalfleck to the terms. The underside of the ornamentation of the top reflects in as, but is trained far less clear. The outer skirt is black dotted.
The egg is yellowish and strongly flattened at the lower end ( hemispherical ). The surface is covered with thin, serrated longitudinal ribs. Near the micropyle one to two sickle-shaped red spots are formed.
The caterpillar is in the base color dark gray to almost black. The fourth, sixth and ninth segment has ever on a white or yellowish-white transverse ridge. The remaining segments are provided with thinner, light brown Querwülsten. The topline is designed as a fine, usually more or less broken double line. The side ridge lines are significantly wider, but also usually more or less broken. On the side of several thin lines are usually present. The caterpillars are very hairy. The whitish to reddish, long hair standing in tufts on warts. The center recessed head is black, reddish brown to light brown.
The doll is rather thick and shiny reddish-brown. The cremaster is flattened with circularly arranged, very short, outwardly curved thorns. The males have six spines, the females four thorns.
Similar Species
The Seladoneule is the Green Eicheneule ( Dichonia aprilina ) are very similar in color. However, these flies only in the fall, so that the flight times almost never overlap. However, the drawing of the front wing is distinctly different. Thus, for example, the agent shadow clearly formed as the wavy line is drawn usually weak.
Geographical distribution and habitat
The Seladoneule lives of the Iberian Peninsula and southern England in the West over large parts of Central Europe, the Balkans, Asia Minor, Russia, Belarus, Ukraine, the Caucasus region through Siberia to the Far East ( Russian Far East, northern China, Japan, Korea). In the north, the range extends to southern Scandinavia and Central Finland. In the south it extends to northern Spain and northern Portugal, northern Italy ( in the Apennines until well after reaching the South ) and Northern Greece. The species is widespread, but nowhere really often. It prefers deciduous and mixed forests, marshes and parklands. In the Alps, it comes up to about 1000 meters altitude before.
Way of life
The Seladoneule forms one generation a year, flying the moth of May to early August. They are nocturnal and fly to artificial light sources. They are occasionally observed at the bait. The caterpillars are found from June to September on the leaves of pedunculate oak Quercus robur ), but also other types of alder ( Alnus ), birch (Betula ), hazel (Corylus ), hornbeam (Carpinus ), poplar (Populus ), flour berries ( Sorbus ), Prunus ( syn. Cerasus ) and hawthorn (Crataegus ). Pupation takes place in a solid cocoon.
The pupa overwinters and is often several years.
Endangering
The Seladoneule is in Germany a kind of early warning. However, the risk situation in the individual federal states looks quite different. In Hamburg it is lost or extinct. In Lower Saxony and North Rhine -Westphalia she is considered high risk, in Brandenburg, Mecklenburg- Western Pomerania, Saxony and Saxony- Anhalt, is at risk.
