Cosmopterix lienigiella
Cosmopterix lienigiella is a butterfly (moth ) from the family of the splendor butterfly ( Cosmopterigidae ).
Features
The moths reach a wingspan of 10-13 millimeters. The head is yellowish brown, has a white center line and two white side lines. The antennae are gray-brown and have a short, white Basallinie. The apical region is more or less curled white. The thorax is yellowish brown and has a white center line. The tegulae are framed yellowish brown and white inside. The forewings are yellowish brown and have in the basal one consisting of five white lines drawing. The Costallinie ranges from 1/4 of the front wing length to the inner, shiny silver napkin. The Subcostallinie starts with 1 /3 of the forewing length and curves away in the middle of the Costa loader. The center line is straight and extends from the wing base to the wing center. The Subdorsallinie is short, it starts at 1/ 3 of the forewing length and ends behind the wing center. Dorsallinie the wing follows the inner edge of the base to the middle. Behind the front wing middle is a yellow band, which tapers towards the inner wing edge. It is surrounded inside and outside each of a nodular, shiny silver napkin. The inner binding is not sufficient to Costa loader and sometimes has a black Subcostalfleck on the outside. The outer bandage is interrupted in the middle. Are black subcostal and Subdorsalflecke on the inside. A white Costalfleck bordered on the outside of the outer, silver napkin. This is extended in the direction of the apex. At the apex there is a slightly curved, white apex line. The fringe scales are yellowish at the cost Alder and on the wing inner margin yellowish brown. The hind wings are yellowish gray. The abdomen is yellowish brown dorsally.
In the males the right brachium is hook-shaped and has a long, pointed apex. It is about eight times as long as the left brachium. The Valven are semi-circular, the upper edge is slightly concave, lower margin nearly straight. The Valvellae are long and asymmetric. In the middle they are bent at right angles. You are almost parallel walls and taper to a point. The right lobe is provided with a hook-shaped outgrowth. The left lobe has a small, irregular, dorsal outgrowth. The aedeagus is can -shaped. His rear portion extends distally and has a ventral flange.
In females, the rear end of the 7th sternite is strongly curved. The eighth segment is one and a half times as wide as long. The ostium is egg-shaped and has a crescent-shaped sclerotization. The sterigma is diamond-shaped, the distal walls are strongly sclerotized. The ductus bursae is significantly shorter than the corpus bursae. The corpus bursae is oval and has two small crescent-shaped signals.
Similar Species
Cosmopterix lienigiella similar Cosmopterix salahinella, differs from this species but by the wider front wing and the narrow center line in the basal region, which does not reach the yellow armband.
Dissemination
The range extends from Europe and North Africa to the Far East to Korea and Japan.
Biology
The caterpillars develop on reed (Phragmites australis). You nate in the leaves and can be found from September to spring. The caterpillars overwinter in the mine. The mine begins as a burrow and expands soon to an elongated space mine. The Raupenkot is first ejected, later, he remains in the mine and is irregularly distributed. The caterpillars nate usually upwards but occasionally down. They are clearly visible in the mine, but finished - unlike other Cosmopterix species - no hiding from spider silk to. A sheet may contain several mines. Pupation takes place in the mine in May. It makes one generation per year, which flies from late May to mid-October. The moths can be easily gekeschert of the plants and to come to light.
