The wingspan of the moth is 35 to 39 millimeters. The color of the forewings is predominantly reddish brown. Ring and kidney defects are light brown or yellowish and filled more or less dark, cone defects are not visible. There is a darker field between the light wavy line and the hem. The hind wings are light reddish gray with clearly protruding veins. The males' antennae, which are strongly combed on both sides, are striking . The females are on average darker in color than the males.
Egg, caterpillar, pupa
The egg is spherical, flattened at the base, finely meshed and shows weak ribs. It is straw yellow in color, has a brown center and a ring. The caterpillars are colored yellow-green and show yellowish lateral lines lined with green upwards. There are reddish or brownish slashes over the secondary back lines. The shiny red-brown doll has two thorns bent forward on the bluntly conical cremaster .
Similar species
- Ring and kidney flaws of the red-brown spring ground owl ( Cerastis rubricosa , Schiff.) Hardly stand out from the basic color of the forewings . There are also some black spots on the costal edge .
- At Cerastis faceta , Tr. the blemishes are usually darker. The most noticeable difference, however, is a whitish ruff.
Geographical distribution and habitat
The occurrence of the species extends over large parts of Europe to Russia and further through Asia to Japan . In the Alps it occurs up to an altitude of about 1500 meters. The yellow-spot spring ground owl can be found in different habitats, for example in mixed forest edges, clearings, bushy valleys, forest raised bogs and heather areas.
Way of life
The yellow-spot spring ground owl forms one generation per year, the moths of which fly from March to May. The moths are crepuscular and nocturnal and visit artificial light sources and the bait . They suckle on blooming pussy willow , their very early flight time runs largely parallel to the willow bloom ( Salix ). The caterpillars live mostly in June and July. They feed on the leaves of various plants, particularly bilberries ( Vaccinium myrtillus ) and blackthorn ( Prunus spinosa ). The species overwinters as a pupa.
Danger
The yellow-spot spring ground owl is widespread in Germany and can be found in large numbers in certain areas, so that it is not considered endangered.
