Cosmopterix scribaiella
Cosmopterix scribaiella is a butterfly (moth ) from the family of the splendor butterfly ( Cosmopterigidae ).
Features
The moths reach a wingspan of 10-11 millimeters. The head shines brown and has a white center and two white side lines. The antennae are brown and have a white line that extends from the front edge of the sensor base to the middle. In Subapikalbereich there are two white portions, the inner consists of three segments, the outer of two segments. The two white sections are separated by a two- brown segments section. The probe tip consists of five white segments. The thorax is brown and has a white center line. The tegulae are brown and have a white line on the inside edge. The forewings are dark brown. In the basal region, there are four narrow white lines. A slightly curved inwards Subcostallinie runs from the wing base to about half of the wing also. A short center line is located above the anal fold. The Subdorsallinie is as long as the center line or a little shorter and a little further away from the wing base. A short Dorsallinie located on the first fifth of the wing inner edge. A wide orange binding runs behind the wing center, it tapers to the wing inner edge and is elongated in the middle thin towards the apex. On the inside borders an obliquely inwardly extending, nodular, pale golden napkin which is not enough to Costa loader. On the outside limits of two nodular, pale golden spots. The Dorsalfleck is about twice as large as the Costalfleck. A small, existing from black scales subcostaler spot or line is located on the outside of the pale golden fascia. The pale golden spots are irregularly edged black on the inside. A white Costalfleck is above the pale golden Costalflecks. A white Apikallinie runs in alignment with the thin extension of the orange napkin. The fringe scales are brown. The hind wings are gray-brown.
In the males the right brachium is strong. It is triangular in shape and has a sharp, stretched out Apex. It is very strongly sclerotized and more than twice as long as the left arm. The Valven are rounded and narrow at the base. The upper and lower edges of which are slightly concave, the Caudalrand is convex. The Valvellae are long, slightly curved in the middle and almost parallel walls. Apical they taper to a blunt point. The aedeagus is cylindrical and narrowed apically. He is curved laterally, the posterior part extends distally and has a small ventral flange.
In females, the rear end of the 7th sternite trapezoidal. The eighth segment is longer than wide. The ostium is round and has crescent Sklerotisierungen. The sterigma is oval and has a long sclerotized distal extension. The ductus bursae is slightly shorter than the corpus bursae and has two distally sclerotized strips. The corpus bursae is oval and provided with two small, equally large and crescent-shaped signals.
Similar Species
Cosmopterix scribaiella differs from Cosmopterix attenuatella and Cosmopterix crassicervicella by the unbroken white line at the probes, the short, not reaching to the front wing base Dorsalline white and the dark brown abdomen. The differences Cosmopterix pulchrimella are described in the articles of this kind.
Dissemination
Cosmopterix scribaiella is native to northern and central Europe, North Africa, Asia Minor and Central Asia. In the Russian Far East and Japan is the nominate subspecies C. s by the japonica ( KUROKU, 1960) represented. After Fauna Europaea the kind in Europe, is widespread. In England, the type was found in 1996 in Dorset and a year later in Hampshire.
Biology
The caterpillars develop on reed (Phragmites australis), where she nate from August until autumn in the leaves. They winter to April in the mine. The mine begins as a straight burrow and then widens irregularly. The mine is similar to that of Cosmopteryx lienigiella. The Raupenkot is stored at the beginning of mine and partially ejected. The caterpillars produce at the lowest part of the mine to a tubular tissue in which they hide. In a sheet there is usually only one mine, but sometimes you can also find up to ten pounds. The infected plant then, viewed from a distance, a withered habit. The caterpillars pupate in May at the lowest point of the mine in a tight cocoon. The moths fly from early June to late October. During the day, they can be easily gekeschert of the food plants. The moths like to come to light.
