Ring and kidney stigma often appear unclear and are sometimes centered with black dots. The hind wings are strikingly dark gray-brown, almost black, and provided at the outer skirt with yellow fringe.

The doll has a red-brown color and often has a bluish tires.
Similar Species
- White-spotted Ulmeneule ( Cosmia diffinis ). Here outweigh slightly lighter reddish brown tones, ring and kidney blemishes are not recognizable. The white spots on Costalrand emerge bigger and brighter.
- Cosmia confinis. This somewhat smaller Southeast European style often has a paler reddish-brown or yellowish tending to the basic color, similar to the drawing diffinis more and also has lighter hind wings compared to affinis.
- Violet Brown Ulmeneule ( Cosmia pyralina ). In this type usually lack the white spots entirely on Costalrand, only an elongated, bright, blurred sign near the wing tip is visible.
Dissemination

The caterpillars are preferred to be found on elms (Ulmus ) and especially between spun together leaves. Chance of it (Prunus spinosa) were found but also of oak (Quercus ), lime (Tilia ) or Blackthorn. They live from May to June and are regarded as murder caterpillars ing that they are both in nature, but especially during the breeding cramped spaces, the caterpillars of other species, occasionally even other dogs, and suck it dry.
