Cosmopterix lienigiella is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae).
features
The moths reach a wingspan of 10 to 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 basal line. The apical area is more or less ringed white. The thorax is yellowish brown and has a white midline. The tegulae are yellowish brown and outlined in white on the inside. The forewings are yellowish brown and have a drawing consisting of five white lines in the basal region . The costal line extends from 1/4 of the forewing length to the inner, silvery shining band. The subcostal line begins at 1/3 of the forewing length and curves away from the costalader in the middle . The center line is straight and extends from the base of the wing to the center of the wing. The subdorsal line is short, it begins at 1/3 of the fore wing length and ends behind the center of the wing. The dorsal line follows the inner edge of the wing from the base to the middle. Behind the center of the forewing there is a yellow band that tapers towards the inner edge of the wing. It is surrounded inside and outside by a bumpy, silvery shining band. The inner band does not reach the costalader and occasionally has a black subcostal spot on the outside. The outer band is interrupted in the middle. There are black subcostal and subdorsal spots on the inside. A white costal stain borders the outer, silvery band. This is extended towards the apex . There is a slightly curved, white apex line at the apex. The fringed scales are yellowish on the Costa loader and yellowish brown on the inner wing edge. The hind wings are yellowish gray. The dorsal abdomen is yellowish brown.
In the male, the right brachium is hook-shaped and has a long, pointed apex. It's about eight times as long as the left brachium. The blades are semicircular, the upper edge is slightly concave , the lower edge almost straight. The valvellae are long and asymmetrical. In the middle they are bent at right angles. They are almost parallel-walled and taper to a point. The right lobe has a hook-shaped outgrowth. The left lobe has a small, irregular, dorsal outgrowth. The aedeagus is can-shaped. Its rear part widens distally and has a flange ventrally .
In the females the rear end of the 7th sternite is strongly arched. The 8th segment is one and a half times as wide as it is long. The ostium is egg-shaped and has a crescent-shaped sclerotization. The sterigma is diamond-shaped, the distal walls are more heavily sclerotized . The ductus bursae is significantly shorter than the corpus bursae. The corpus bursae is oval and has two small sickle-shaped signs.
Similar species
Cosmopterix lienigiella is similar to Cosmopterix salahinella , but differs from this species by the broader fore wings and the narrow midline in the basal region, which does not reach the yellow band.
distribution
The distribution area extends from Europe and North Africa to the Far East , to Korea and Japan .
biology
The caterpillars develop on reeds ( Phragmites australis ). They mine in the leaves and can be found from September through spring. The caterpillars overwinter in the mine. The mine begins as a feeding tunnel and soon widens into an elongated open space mine. The caterpillar droppings are first thrown out, later they remain in the mine and are distributed irregularly. The caterpillars usually mine upwards, but occasionally also downwards. They are clearly visible in the mine, but - unlike other Cosmopterix species - they do not make hiding places out of spider silk. A sheet can contain several leads. Pupation takes place in the mine in May. The species forms one generation per year that flies from late May to mid-October. The moths can easily be nested from the plants and come to light .
