Features
Butterfly
The moths have a wingspan of 28 to 32 millimeters and strong violet-brown to dark reddish brown or burgundy colored forewings. Waves and transverse lines are obscured, but often occur out not very strong. At the apex there is a whitish slash. The Saumfeld is brightened somewhat. Ring, kidney, and Zapf blemishes are blurred and only hinted at. The hind wings are provided uniformly gray-brown with lighter and fringes.
Caterpillar, and chrysalis
The caterpillars have a green color as well as white - back and side- back lines and a yellow side stripes. In addition, some white dots. The pupa is light brown in color, has a bluish tires and has two downwardly curved thorns on the cremaster.
Similar Species
- Typical of the Red-brown Ulmeneule ( Cosmia affinis ) are two white spots on the forewing Costalrand. Striking are also the very dark colored hind wings.
- In the White-spotted Ulmeneule ( Cosmia diffinis ) and in Cosmia confinis white spots occur most Costalrand shining beacon, whereas the whitish slash at the apex is missing.
Dissemination
The species is widespread in Central Europe, in the north to the Midlands and the south Fennoskandinaviens, south to northern Spain and central Italy and east by Bulgaria to the Caucasus and on through Asia to Korea and Japan. In the Alps, it rises up to 1600 meters. The Violet Brown Ulmeneule is mainly to be found but in mixed forests, meadows and valleys on orchards and in gardens and parks.
Way of life
Main flight period of moths are the months of June to August. They are nocturnal and visit artificial light sources and bait. As food plants serve the caterpillars, not so much on elms (Ulmus ) are bound as affinis and diffinis, various fruit trees, and willows ( Salix), oak (Quercus ) and other deciduous trees. They live from May to June and are regarded as murder caterpillars, ie they engage both in nature, but especially during the breeding cramped spaces, the caterpillars of other species, occasionally even other dogs, and suck it dry. This behavior is for example also of the caterpillars of the related Trapezeule ( Cosmia trapezina ) and other Cosmia species are known. They pupate in a cocoon between plant parts. The egg overwinters.
Endangering
The species is widespread in Germany, only in a few regions rare and is classified on the Red List of Threatened Species as not at risk.
