Features
Butterfly
The wingspan of the butterfly is 31 to 37 millimeters. The coloration of the forewing varies slightly, the basic color is dark brown. Ring and kidney blemish are light brown and clearly highlighted, sometimes filled yellow white and gray, or even nearly pure white with a small dark spot in the middle. Zapf blemishes are not visible or very indistinct. Occasionally a whitish Basalstrich be seen. All transverse lines show brightened slightly. The hind wings are gray-brown without markings.
Egg, caterpillar, pupa
The egg is spherical, ribbed, flattened at the bottom and straw. In youth, the caterpillars are blackish, grown gray black and greasy shiny. The belly is grayish white, a broad dorsal line dark. On each segment, except on the last one, are on the side of the back line, two yellow brown wedge-shaped strokes that are connected together on the first two segments. The doll is bright yellow with two peaks at the cremaster.
Similar Species
The until recently operated as a subspecies of Eurasian Euxoa adumbrata Eversmann, 1842 is similar but Euxoa lidia is larger, darker, has narrower forewings and only outlined in white kidney blemish. After Warnecke, the former subspecies have been isolated during the last ice age in different regions, so that the location can be used as a criterion for distinction. Superficially resembles Euxoa lidia also some forms of Euxoa tritici - species complex and other Euxoa species, but how Euxoa nigricans or Euxoa vitta is, usually to the distinctive call waiting and in particular to the one half white and black, sharply divided ruff good indistinguishable. Based on the documented description of Kozhanchikov of the genitals can be a unique assignment.
Geographical distribution and habitat
The species occurs or occurred only in the coastal regions of Belgium (?), The Netherlands, northern Germany ( probably extinct) and Denmark. Former Northern and Eastern European evidence be attributed to the type Euxoa adumbrata ( Eversmann, 1842) today. Euxoa lidia prefers warm and dry places in the coastal areas, such as sandy heaths.
Way of life
Euxoa lidia is one generation per year. The nocturnal moths fly between July and August. They come to artificial light sources and visit the bait. The nocturnal caterpillars feed on various low plants and grasses, such as dandelion (Taraxacum ) or Vogelknöterichen ( Polygonum ). They overwinter and pupate in May of the following year in a cocoon in the soil.
Endangering
The species is extinct in Germany almost certainly. The recent finds date from the mid-twentieth century. Therefore on the red list of endangered species is classified in Category 0 ( extinct or lost ). She is considered one of the rarest cutworm species in Europe
