Chrysoclista linne ella is a butterfly (moth ) from the family of the grass leaf miner ( Elachistidae ).
Features
The moths reach a wingspan of 10-13 millimeters. The head is dark brown. The sensors shine gray brown dark, at the top there are about 10 white segments. Thorax and tegulae shining greyish brown. The front wings are bright orange and edged broad black-brown. The border is narrowest at the Costa loader. The wings drawing consists of three round, warty, silvery spots. The first spot has a tuft protruding, black-brown scales and is located at 1/ 3 of the forewing inner margin. The second is located just before the half of the Costa loader length, the third at 2/3 the length of the wing inner edge. A silvery line lies in the wing base, another is located opposite the outer Dorsalfleck on the Costa loader. The fringe scales are gray-brown. The hind wings are brownish gray and have a bronze sheen. In some specimens the orange ground color of the forewing may be partially or completely obscured. In females, the silvery spots and dashes are larger on the fore wings.
In the males, the Gnathos - arms are very short, rounded and strongly serrated. The Tegumen is longer than wide. The Valven are clipped distally and slightly dilated. The Anellus - lobes are strongly widened distally and have inside a semi-circular indentation subapikale; the apex is perforated. The aedeagus is strongly curved and has a forked tip. The cut and the shape of the Valven Anellus lobe characteristic of the species.
In females, the posterior Apophyses are about twice as long as the anterior Apophyses. The eighth tergite is sclerotized and laterally concave. The genital plate has a triangular sclerotization. The antrum is quite wide and has a rectangular, weakly sclerotized extension. The ductus bursae is narrow and widens gradually to the corpus bursae. It is less than 1.5 times as long as the corpus bursae. The corpus bursae is dilated and oval distally.
Dissemination
Chrysoclista linne ella is widely used in Europe. In the north, the range extends to the south Fennoskandinaviens. Evidence from Asia Minor are considered unsafe. In North America, the species was introduced in the first half of the 20th century. In the U.S., they found the moths, 1928 in New York. Since then, the species has continued to spread and is now in the state of New York, located in New Jersey, near Boston in Massachusetts, Connecticut and Vermont. For Canada only evidence from Ontario and Nova Scotia are.
Biology
The caterpillars develop on -leaved lime (Tilia cordata) and Dutch linden (Tilia europaea). Older evidence of beech (Fagus ) and apple trees (Malus ) are subject to confirmation. The caterpillars live from August to May in feeding programs and round chambers under the bark of tree trunks. The infestation can be seen on light brown Raupenkot who comes in cracks in the bark to the fore. Preference is given to old trees and those that are weakened by annual pruning. The caterpillars pupate within the insect holes, but full-grown caterpillars have also been found in dried leaves, suggesting that they also leave the feeding tunnels pupation. It makes one generation a year, the moths fly from May to August. They rest on the bark of host plants or run around. Butterflies can only very rarely observed in natural habitats. Often they are found, however, in large numbers in towns with avenues of trees.
System
The species of the genus Chrysoclista were often assigned to the genus Glyphipterix Hübner. The name linne ella was often misspelled: line ella, linnaeella, linnaeanella. From the literature, the following synonyms are known:
- Phalaena linne ella Clerck, 1759
- Elachista gemmatella Costa,
- Elachista linnaeella Zeller, 1839
- Oecophora schaefferella Duponchel in Godart,
- Lita linne ella ella Bruand var obscuri - linne, 1859
