Features
The moths reach a wingspan of 10-13 millimeters. The forewings are dark drawn in black and white. Yellowish orange lines are missing, only a few ocher-colored scales form a reasonably clear subbasale binding. The vane inner edge is more or less pure white and has very few dark scales.
In the males, the Gnathos has two long thin arms, each ending in a small prickly bump. The Anellus lobes are moderately bent and have a rounded apex. They lack the ventral clearly salient extension. The aedeagus has no distinct blunt keel. The vesica bears 3-4 sting groups, one of which is 1.5 to 2 times longer than the others. The Genitalaramatur of the males is similar to those of Blastodacna atra and Blastodacna rossica, these can be distinguished by their rounded tips as bright ella mainly by those in the apical half distinctly curved Anellus - cloth.
In females, the genital plate, which surrounds the ostium, triangular, tapering laterally. It is provided with individual needles. The corpus bursae is ovate, the Signum is granulated horn-shaped and fine. The genital armature of the females may be determined by laterally tapered genital plate and the slightly sclerotized and smaller bubble-shaped section of the ductus bursae be distinguished from Blastodacna atra and Blastodacna rossica.
Similar Species
Similar species are Blastodacna atra and Blastodacna rossica, the differences are described in the articles.
Dissemination
Blastodacna brighter ella is widespread in Europe with the exception of the north. In the east, the range extends to the Caucasus. The moths can be found at the edges of woods, in parks and gardens where hawthorn grows.
Biology
The caterpillars develop on Zweigriffeligem hawthorn (Crataegus laevigata ) and Eingriffeligem hawthorn (Crataegus monogyna). As another host plant (Prunus spinosa), plum (Prunus domestica) and apples (Malus ) are mentioned in the literature Blackthorn, but these data require confirmation. Most of these relate B. atra, the details of major damage to apple trees in Japan are believed to be erroneous and attributable to the web and Knospenmottenart Argyresthia conjugella. The caterpillars evolve from summer to autumn in the berries. Infested berries can be seen from a hole on the side. The caterpillars pupate in late autumn in a loose cocoon in rotting wood or in the ground. It makes one generation a year, the moths fly from May to August. The moths are nocturnal and come to light.
