features

butterfly

There is a pronounced sexual dimorphism between the sexes . The wingspan of the males is 27 to 30 millimeters. The front and rear wings are mostly matt red-brown to gray-brown and almost without drawings. The area below the front edge is more intensely colored on the front wings. Sometimes a weakly darkened shadow can be seen in the area of ​​the post-fiscal region . The hind wings always show slightly lighter shades. The flightless females have only short wing stubs, a plump body shape and are gray-brown.

egg

The egg is yellowish, oval in shape and covered with a network of short ribs. The micropyl zone is surrounded by a ring of deep pits.

Caterpillar

Adult caterpillars are green-gray in color and show seven light, wavy longitudinal lines, a dark longitudinal stripe and individual bristles. The ventral side is yellowish, the head is flesh-colored and the anus is reddish in color. When fully grown, the caterpillars can reach a length of up to 26 millimeters.

Doll

The shiny black-brown pupa is relatively wide in the front area and tapers rapidly towards the rear end. The cremaster is provided with a few thorns.

Geographical distribution and occurrence

Lignyoptera fumidaria occurs in eastern Austria , Hungary , Bulgaria , Romania and some eastern regions of the European part of Russia . The species inhabits meadow landscapes.

Way of life

The species that belongs to the frost tensioners flies in the months of October to December. In older literature, only yarrow ( Achillea millefolium ) is mentioned as a food plant for caterpillars . Experiments by Kasy showed that the caterpillars in breeding also accepted gold aster ( Galatella linosyris ), scabiosa knapweed ( Centaurea scabiosa ), meadow sage ( Salvia pratensis ) as well as plantain ( Plantago ) and elephant species ( Inula ) as fodder plants. Confirmation that these plants are also part of the diet in the field is still pending. The species overwinters as an egg.
