features

butterfly

The wingspan of the moth is 21 to 29 millimeters. The basic color of the forewings is creamy white to bright white. The root and middle field are colored black-brown to blue-black. The latter is crossed by two bright transverse lines. In the center there is a deep black, jagged central point. In the light areas between the root and middle field as well as in the border area, gray or black spots of different types can be seen. The hind wings are whitish and show a small black central spot.

egg

The egg is sulfur yellow in color. The surface is provided with weak ribs.

Caterpillar

Adult caterpillars are brownish in color. On the back they show bright angular signs, the tips of which point backwards. They also have light side stripes.

Doll

The pupa is usually red-brown and shiny. The cremaster is flattened briefly and provided with four long, outwardly curved end spines. There are fine bristles on the sides and on the back.

Geographical distribution and occurrence

The black-eye binding spanner is widespread in Western and Central Europe including the British Isles . In the east it occurs to the Central Asian mountains, in the south to Asia Minor and Kyrgyzstan . In the Alps it can still be found at an altitude of 1500 meters. The species inhabits many different habitats, including deciduous and mixed forests as well as heather, shrubbery and park landscapes.

Way of life

The nocturnal moths fly in a first generation from early May to early July and in some areas in a second from mid-July to late September. At night they visit artificial light sources . The caterpillars feed on the leaves of different types of bedstraw ( Galium ). They overwinter in a solid housing on the surface of the earth and pupate in it in spring.

Danger

The black-eyed tie-tensioner occurs in all German federal states and is not considered endangered.
