features
butterfly
Both sexes have different sizes. The female moths reach wingspans of 32 to 53 millimeters, the males 28 to 40 millimeters. The color of the forewings varies from yellow-gray to gray-brown to chestnut brown. Sometimes a few small, dark spots can be seen. The hind wings are not marked and colored light ocher to brown-gray. The abdomen clearly exceeds the length of the wing - especially in the case of female butterflies. The antennae of the males are long, double-combed, those of the females are only short comb-toothed.
egg
The egg is elongated, rounded on the sides and white-gray in color.
Caterpillar
Adult caterpillars are slender, elongated, slightly flattened on the underside and dirty white in color. They have two indistinct brown, broken back lines. The head and the first two breast plates show brownish tones.
Doll
The brown-gray pupa is elongated and has several rows of thorns on the back as well as dark wing sheaths and a beak-like frontal process.
Distribution and occurrence
The tube bit is widely used in most of the reed areas in Europe and Asia and has also been detected in Japan and Taiwan . It is also native to some parts of the landscape in North Africa. The species prefers to live in reed beds, on flat moors, swamp meadows and on the banks of rivers, streams, ponds and lakes.
Way of life
The male moths fly mainly in the late evening and at dawn. They also like to visit artificial light sources . The main flight time of the species are the months May to August. The caterpillars use the reed ( Phragmites australis ) as a forage plant , in whose shafts the animals live and pupate. The development of the caterpillars is two years.
Danger
In Germany, the pipe drill occurs in different numbers, in the northern regions numerous, in Baden-Württemberg , however, it is on the warning list. Although the species is not classified as endangered on the Red List of Threatened Species , because of its attachment to the reed, the species is threatened wherever this vital plant is in decline, e.g. B. by draining.
