In Turkey, Iran, Armenia and Turkestan the similar style Eugnorisma ponticum (Staudinger, 1891 ) occurs, which is somewhat smaller with a wingspan 31-38 mm and also with of Eugnorisma depunctatum and Eugnorisma arenoflavidum by the pale gray hind wings a broad darker outer band and different kind of genitals is different.
Geographical distribution and habitat
The basal spot - Bodeneule is widely used in Europe, west to England, north to Scotland and Fennoscandia, south to southern France, southern Italy, Sicily and Greece, also in the east to the Caucasus and Turkestan. In northern France, the Benelux countries and some western regions of Germany, however, it is also missing on most Mediterranean islands. It occurs both in dry areas, such as pagans or warm slopes, as well as in mixed forests, moist stream valleys and parks. In the mountains it is still to be found at altitudes of 1500 meters.
Way of life
The basal spot - Bodeneule is one generation per year, flying moths whose July-September. The moths are nocturnal, and come to the bait as well as artificial light sources. The females lay eggs in small clutches. The larvae feed after hatching the egg shells and live in small groups. They overwinter without feeding. In the spring they feed on various plants, such as Soft lung herb ( Pulmonaria mollis ), deadnettles ( Lamium ), bilberry (Vaccinium myrtillus) or stinging nettle (Urtica dioica). The caterpillars feed mostly at night. They pupate in May mainly in a hole in the ground.

The species is not detected in all provinces, but is not classified as acute danger in Germany on the Red List of Threatened Species.
