With a wingspan from 26 to 32 millimeters count the butterflies to the smaller cutworm species. The forewings are gray brown and show strip-shaped, white -gray interference. The name derives from the striking prominent crescent-shaped, white kidney blemish. The ring stain are boxed punctiform and black. The midfield, which is framed by bright lines cross is narrow and obscured. At the outer edge of the fringe is alternately colored brown and white.

Similar Species

  • The moths of Calophasia hamiferaii have a generally darker and poorer contrast appearance.

Geographical distribution and habitat

The occurrence of the species extends throughout Central and Southern Europe to Russia and Central and East Asia. But you're lacking in Japan. In order to combat toadflax ( Linaria ) the Möndcheneule was introduced in 1965 in North America and therefore is also found in parts of Canada and the United States. In the Alps it is found up to 2000 meters in altitude. The species prefers inhabited warm slopes, heathland and Ödländereien.

Way of life

The Möndcheneule forms depending on the region two or three overlapping generations; in Scandinavia, it is only one generation, in southern Europe it is up to three generations. The moths fly correspondingly from April to September. They are mostly active at dawn, but also visit the day flowers, such as those of bladder campion ( Silene vulgaris). Only occasionally they appear at night with artificial light sources or applied baits. Up to 400 eggs are laid individually or in small groups, to the underside of the leaves or the stems of crop plants of the crawler. These are different Leinkrautarten ( Linaria spp.). The caterpillars of all stages feed on the leaves, flowers and finer stems. Pupation takes place in a tough silken cocoon, is included in the organic material, on the ground or in the leaf litter. The species overwinters as a pupa, a part of the population might overwinter as a caterpillar.

Under favorable growth conditions (21 ° C and 16 hours of daylight ) the Möndcheneule need 55 up to 56 days development time of the filing of the egg to hatch the moth. The development time is greatly dependent on the temperature. How does the development at 30 ° C, only about 25 days. The lower limit at which the manner yet to be developed is located at about 13.5 ° C.

Endangering

In Germany the Möndcheneule occurs mainly in the southern and central provinces. It is listed on the Red List of Threatened Species as not at risk.
