Kidney and ring flaws are large and noticeable. Typically, the ring blemish is whitish, the kidney blemish is red-brown. A yellow-white oblique wipe often extends under the ring flaw to the inner corner , which is often interrupted in brown in the middle.

Adult animals have an interrupted reddish topline and reddish-brown slashes. They also show indistinct side stripes and white stigmas that are lined with black. The green head has two dark lines. The red-brown doll has a weakly divided Kremaster tip .

Similar species

The gray field herb owl ( Lacanobia (Lacanobia) w-latinum ) differs in the following features:

  • Wingspan usually larger (36 to 41 millimeters),
  • Post-fiscal region broadly laid out in gray,
  • Ring blemishes mostly filled with gray-brown,
  • yellow-white oblique wipe to the interior corner is missing,
  • W-signs in the wavy line stronger and arrow spots less developed,
  • Hind wings somewhat darker in color.

Geographical distribution and habitat

The species is widespread in Europe and extends through the temperate zone to East Asia (including Japan ). In the Alps it rises to an altitude of around 2000 meters. The main habitat are light forests as well as bushy heathland areas and sandy lawns with overgrown vegetation.

Way of life

The moths are nocturnal, fly from May to August, occasionally suckle on the blossoms of butterfly lilacs ( Buddleja davidii ), like to appear near artificial light sources and occasionally also on bait . The caterpillars live from August to September. They feed on the leaves unterschiedlichster plants, such as blackberries ( Rubus ), blueberries ( Vaccinium myrtillus ), blackthorn ( Prunus spinosa ), broom ( Cytisus scoparius ), heather ( Calluna vulgaris ), silver birch ( Betula pendula ) and others. The species overwinters as a pupa.
