Batrachedra praeangusta is a butterfly ( moth ) from the family of batrachedridae .
features
The moths reach a wingspan of 14 to 15 millimeters. The head, thorax and tegulae are white and mixed with gray. The antennae are curled grayish and dark gray. There are two white rings in the area of the probe tip. The forewings are white and heavily speckled with dark gray scales . A broad blackish line runs through the Kostalfold near the base of the wing, which is interrupted in the middle and distally by yellowish white dots. At the base of the wing inner edge there is an indistinct blackish spot that almost reaches the blackish line of the Kostal fold. In the middle of the fore wing there is a blackish line, which is interrupted in the middle by a yellowish white spot. A broad, yellowish white line extends from the base of the wing to 2/5 of the fore wing. There are yellowish white spots in the tornus (inner corner). In the apical area there are three yellowish white lines on the Kostalader, two yellowish white lines extend from the fringing area to the inner corner. The fringed scales are gray and mixed with white at the wing tip. The hind wings are glossy gray and become lighter towards the base of the wing.
Similar species
Similar species are Batrachedra pinicolella and Batrachedra parvulipunctella , which differ from Batrachedra praeangusta by their white and gray fore wings, respectively .
distribution
The species is native to all of Europe with the exception of the extreme north and south-east. In the east the distribution area extends into the Caucasus and Central Asia as well as over the south of Siberia to the Russian part of the Far East .
biology
The oligophagous caterpillars live on various willow plants such as white poplar ( Populus alba ), aspen ( Populus tremula ), white willow ( Salix alba ) and sal willow ( Salix caprea ). They develop from April to June (according to other sources from May to June) in the female catkins of willows and poplars , where the first track stadiums in flowers and seeds minieren . Later stages live in silky webs between the seeds. Sometimes the caterpillars also drill into the bud base and hollow it out completely. The partially ejected droppings are visible in the form of a small pile in the middle of the bud. The last stages of caterpillars also feed between young leaves. The adult caterpillar leaves its web to pupate in cracks in the bark of its host plant. The very slender brown pupae lie in a tapering felt-like cocoon , which is covered with pieces of lichen. The flight time of the moths extends from June to August, according to another source from the second half of June to the beginning of September. The moths often walk around on tree trunks and are attracted by artificial light sources .
