features

The moths reach a wingspan of 38 to 44 millimeters. The head and body are dark brown. The forewings are relatively wide with a relatively pointed apex and an almost straight hem. The basal third is dark brown, the border to the light central band is evenly curved, with the exception of a slight kink about halfway. The central band is light gray, sometimes silvery in appearance, and widens from the center to the rear edge and the front edge. It is also sharply set off from the outer dark brown field and extends to the wavy line. This white line is concave towards the basal at the front edge. In this concave area, the line is relatively wide, in the further course only very narrow; First there is an acute-angled bulge to the side, then a wide and flat bulge and a rounded, wide and flat bulge to the rear edge. The hem field is gray-brown, becomes significantly more light gray towards the hem edge. From the apex a dark brown wedge-shaped spot extends obliquely to the dorsum , followed by a tooth-shaped, outward-facing spot. The fringes are light brown. The hind wings are dark brown with an indistinct light band on the basal third of the hind wings. The border area is white. The underside of the wings is colored slightly reddish brown, which turns into a gray tone towards the outer edge. The undersides of the fore and hind wings each have a small discal spot and very fine transverse lines.

The egg is gray-brown. The caterpillars are about 42 to 48 millimeters long when grown. Your body is relatively slim; the coloring brown. The back line is red-brown, the side back lines, on the other hand, are colored light brown, as are the side lines. The eleventh segment has a cream-colored transverse line, the spiracles are black. The head is brown with yellow markings. The approximately 16 mm long reddish-brown doll is relatively short, its cremaster has only a few bristles.

Geographical distribution and habitat

The distribution area of ​​the species extends from Spain and Morocco in the west across southern Europe and North Africa , Asia Minor , southern Russia to Iran , Afghanistan , Turkmenistan and Kyrgyzstan . In the north the distribution area extends to western France and to southern Germany , eastern Austria ( Burgenland , Lower Austria ) and Hungary . In the southern Alps , the species rises up to 700 meters.

Way of life

Dysgonia algira forms two to three generations per year. The moths fly from April to October and are nocturnal. They are attracted to artificial light sources and can be baited. The eggs are laid individually on the host plants. The caterpillars mainly feed on blackberries ( Rubus fruticosus agg.), But also on willows ( Salix ), gorse ( Genista ), purple loosestrife ( Lythrum ), pomegranates ( Punica ), wonder tree ( Ricinus communis ) and glass herbs ( Parietaria ). The pupation takes place in a loosely spun cocoon , hibernating the doll.
