features

butterfly

The moths have transparent wings that are only scaled on the wing veins , the discal spot and the wing edges. They reach a wingspan of 14 to 25 millimeters. The forewings are reddish in color at the edges. The fringes are brownish. In the middle a crescent-shaped, black-brown or red-brown discal spot can be seen, which extends from the front to the rear edge. The hind wings have a narrow dark band and a small black-brown discal spot. The head, antennae , thorax and abdomen have a blue-black sheen. There is a red ring on each of the fourth and fifth segments of the abdomen. Sometimes the sixth segment is also colored reddish. The anus tufts are strongly fan-shaped, bluish-black in color and have yellowish white hairs on the sides.

Similar species

There is a certain resemblance to the red dock glass winged ( Pyropteron chrysidiformis ), which also has reddish dusty forewings , but shows whitish rings on the segments of the abdomen and whose anal bush is hairy red.

Geographical distribution and occurrence

The willow glass-winged bird is common in almost all of Europe, but is absent on most of the Mediterranean islands. It is also found in Ukraine , the northern areas of Asia Minor and the Black Sea coast, as well as in the Caucasus region. The species was detected at altitudes of 2200 meters. Their main habitat are brook and river edges, floodplains, swamp forests, raised bogs and pasture cultures.

Way of life

The diurnal moths fly in the months May to July, at higher altitudes until August. They are particularly active in the sunshine. They like to visit the flowers of various plants, for example those of elder ( Sambucus ), Dost ( Origanum ), ragwort ( Senecio ), privet ( Ligustrum ) or raspberry ( Rubus idaeus ). Male moths also fly to pheromone traps . The maggot-shaped caterpillars live under the bark of various types of willow ( Salix ) as an annual or two-year-old , and more rarely in the trembling aspen ( Populus tremula ). They prefer injured, sick, or older trees. In particular, they are found in cancerous growths. The caterpillars overwinter and pupate in spring at the end of the feeding tunnel under the bark of the food plant.

Danger

In Germany, the willow glass-winged bird occurs in all federal states and is classified as not endangered.
