The tubular sack carrier ( Taleporia tubulosa ) is a butterfly from the family of the real sack carrier (Psychidae).
features
butterfly
The adult animals are characterized by a clear sexual dimorphism . The elongated wings of the males reach a span of about 16 to 20 millimeters, have a glossy gray-brown to yellowish-brown basic color and usually show an indistinct net-like pattern. There are long fringes on the edge of the wing. Female animals resemble maggots , are reddish brown in color, have a cylindrical body and a tuft of yellow-gray anus wool on the abdomen. They do not have wings, but have well developed legs.
Caterpillar
The caterpillars are colored white-yellow, have a black-brown head and breast shields. You spin yourself into a sack-like living tube. Their cross-section is round to triangular, about 14 to 16 millimeters long and has a uniform diameter of two to three millimeters. The caterpillar attaches tiny plant particles and grains of sand to the outside.
Similar species
- The similar male moths of Taleporia politella can be distinguished by their slightly larger wingspan, the more elongated, more clay-yellow colored and less reticulate wings. The tube is also a bit longer.
Distribution and occurrence
The species is locally widespread in Europe, from southern Scotland through western and central Europe, east to Russia , to the Balkans and in the north to the high latitudes of Fenno Scandinavia . For the Mediterranean towards them is less frequent. In the mountains it can still be found at an altitude of 1,800 meters. The animals predominantly inhabit deciduous and coniferous forests.
Way of life
The male moths fly from May to July. They rarely visit artificial light sources . During the entire caterpillar stage, the caterpillar remains in its protective cover and also pupates in it. The male adult butterfly leaves the caterpillar sac and seeks out the flightless female, who sits on the outside of the sac tube, to mate. Both sexes have a very short lifespan of just a few days. The caterpillars prefer to feed on green algae and various types of wood and lichen. The larval sac tube of the animals is attached to trunks, posts and walls at a height of usually one to two meters.
Danger
The species can be found in large numbers in all federal states in Germany and is therefore classified as not endangered on the Red List of Endangered Species .
