The moths reach a wingspan of 37-67 millimeters, while the females are usually much larger than the males. Their forewings are fine light gray patterned and have two to four dark spikes bind to. In the males, the middle third of the leaf is often darker brown or gray. There are both very bright shapes in which one can see only the dark jagged bars on a light background, in extreme cases, as well as dark shapes that are one color dark brown or dark gray.

Your base color is initially weißlichgrün or yellow-green, later full yellow green or pinkish brown. The animals are hairy striking. They carry numerous long, the basic color matched hair on the sides; on the back until after the seventh segment. On the segments four to seven, they have very dense, likewise as the basic color or very light colored, upward hair brush. On the eleventh segment they carry another, but looking back, red or orange -colored hair brush that has considerably fewer, but longer hair than the other tufts. The pink-colored caterpillars whose color varies also to black. Between the segment rings the entire caterpillars are black in color. These areas can be seen clearly when the caterpillars curl up in danger. On the underside, the caterpillars are also jet black.
Through the red tuft of hair on the abdomen of the caterpillar moths are also called Redtail. This name is also still used for the singing birds of the genus Phoenicurus, to which both the garden and Black Redstart.

Occurrence
The animals are used in almost all of Europe, except in the far north and parts of the Mediterranean, east to the Caucasus front. They live mainly in deciduous forests, but also in hedgerows, parks and gardens. They are common and widespread.
Way of life
The nocturnal moths can be attracted by artificial light, particularly the males are attracted to the light. The animals stretch in its rest position their front legs forward, which is why they also get their German names.
Flight times and caterpillars
The moth flies in one generation in the period from May to June, the caterpillars are found from July to October.
Food of the caterpillars
The caterpillars feed on various deciduous tree and shrub species, especially of goat willow (Salix caprea ), hornbeam (Carpinus betulus ), beech ( Fagus sylvatica), oak (Quercus robur), common hazel (Corylus avellana ), silver birch (Betula pendula), apple tree (Malus domestica) and rowan (Sorbus aucuparia ).
Development
The females lay single- Eispiegel from up to 300 eggs in bark or branches. Initially, the caterpillars live sociable, closely packed. However, they are loners early age. When molting young caterpillars are sitting on a woven padding on the underside of leaves, older caterpillars pull up to in rolled-up leaves back. Pupation takes place on the ground between leaves in one, with her hair displaced, gray or brown to yellowish cocoon. The pupa overwinters, the moths emerge only in the spring, at appropriate temperatures. From historical times, outbreaks of the beech stretching the foot are known. However, since these occur late in the year, they have little influence forestry.
