Evergestis sophialis is a butterfly from the family of Crambiden ( Crambidae ).

features

The moths reach a wingspan of 23 to 33 millimeters. The forewings have a white to pale bluish white basic color and are heavily overlaid by a transverse pattern of blackish and light brown scales , which cause an overall dark color. The transverse lines are white and toothed differently. The post median line has a black border on the inside. The fringed scales are whitish and drawn with two dark lines that are interrupted at the end of the wing veins. The hind wings are dirty white and darkly mottled , especially towards the apex . The post median line is white and noticeably curved. The hemline is narrow and white. The fringed scales are white and dark in the first third. The underside of the forewing is strongly mottled dark and has a toothed, whitish post-median line that is darkly bordered. The underside of the hind wing is less markedly darkly spotted and drawn with a strong, curved, dark post-median line. The apex is darker. From different localities darkened to uniformly dark colored specimens are known (= Evergestis sophialis ab. Suffusa Skala , 1928).

In the males, the uncus is sparsely haired. It is tapered and has a sharp point. There are about 5 short teeth at the top of the gnathos . The blades are only slightly tapered, the clusters are represented by a patch of short, bulbous hairs at the base. The distal part of the aedeagus is provided with two dense groups of cornuti and well-developed brush-like pillows.

In females, the corpus bursae has an irregularly egg-shaped shape. The Signa are big. The ductus bursae is narrow and bulbous in front of the colliculum .

Similar species

The similar species Evergestis frumentalis , Evergestis segetalis and Evergestis dilutalis have a similar forewing pattern , but this is more brown than gray. Evergestis lupalis poecilalis is more strongly drawn and has a conspicuously dark center line between the whitish antemedian and postmedian lines. The hind wings are darker and the post-median line is more pronounced towards the anal angle . The distinguishing features of E. sophialis and Evergestis lupalis are listed for the latter species.

distribution

In Europe Evergestis sophialis is distributed from Spain and France across Central and Southern Europe to the south of the European part of Russia . The species is absent from the British Isles , Scandinavia and Corsica . Further in the east, the distribution area extends to the south of Siberia.

biology

The caterpillars develop on common broom mustache ( Descurainia sophia ) and on various species of rocket ( Sisymbrium ). The moths fly from April to August, in Central Europe from June to July. You can find them in open country , on fallow land and on roadsides. They are easily roused and come to light .
