The evergestis forficalis ( evergestis forficalis ) is a butterfly from the family of Crambidae . The species is widespread across Europe.

features

The moths reach a wingspan of 28 to 33 millimeters. The forewings are ocher-colored and slightly dusty brown at the wing tips. They each have two discal spots, the dorsal spot is significantly larger. They also have numerous slightly curved or wavy transverse lines; the transverse line from the apex to the dorsum is very distinct. The hind wings are whitish with a light brown line that runs parallel to the outer edge. However, this can also be broken down into a number of points. The underside is whitish. The discal spots are strongly developed, but the transverse lines of the upper side are only indistinct.

Way of life

The cabbage moth forms two overlapping generations each year, which fly from March to September. The eggs are laid in loose groups on the underside of the caterpillar forage plants. The caterpillars feed in loose webs on the underside of the leaves of various cruciferous vegetables , such as horseradish ( Armoracia ), rocket ( Sisymbrium ), garlic mustard ( Alliaria ), Levkojen ( Matthiola ), radishes ( Raphanus ), turnips ( Brassica rapa ), vegetable cabbage ( Brassica oleracea ) and field mustard ( Sinapis arvensis ). The first generation caterpillars grow in just three weeks and pupate immediately. The second generation caterpillars overwinter and pupate only in the next spring.

Occurrence

The species is widespread in Europe with the exception of northern Scandinavia and northern Russia. It occurs across Asia Minor and Central Asia via southern Siberia to Japan and is relatively common in open landscapes and agricultural areas.
