features

butterfly

The wingspan of the moth is 17 to 24 millimeters. The basic color of the forewings is mostly light gray, sometimes with a slight brownish dustiness. Several dark gray transverse lines are wavy and often created twice. The outer transverse line runs near the front edge with a sharp, inward crease. The middle field is lightened in some specimens and bordered by narrow dark bands. The black center point has an oval shape. The hind wings are slightly lighter than the forewings and also have several dark transverse lines and a small black central spot.

Egg, caterpillar, pupa

The egg initially has a whitish, later a brownish-yellow color. The bowl sculpture is provided with hexagonal depressions, which are bordered by straight strips.

Adult caterpillars are brownish and show very distinct red-brown triangular spots on their backs, the tips of which point forward.

The doll is colored black-brown and equipped with two strong and six thin hook bristles on the cremaster .

Similar species

The oak moth ( Eupithecia abbreviata ) has very similar drawing elements. However, this species is larger on average (wingspan of the moth is 18 to 25 millimeters), the basic color tends more to gray-brown tones and the drawing is often more indistinct. As with many flowering species, however, a reliable determination should be carried out by specialists, and a genital morphological analysis is also advisable for clear identification.

Geographical distribution and occurrence

The oak grove moth is widespread in Europe, it is only missing in the very north and in the extreme east. There are local occurrences in Asia Minor , the Caucasus and Morocco . In the Pyrenees and the Alps it rises to heights of 1000 meters. The species prefers dry oak and mixed oak forests.

Way of life

The moths are crepuscular and nocturnal and fly early in the year in one generation in April and May. Sometimes they suck the flowers of the parsley family ( Umbelliferae ). They also appear in artificial light sources . The caterpillars live in June and July and feed on different oak species ( Quercus ), first on the young shoots, later on the flowers. The pupae overwinter.

Danger

In Germany, the oak grove moth occurs in all federal states and is listed on the red list of endangered species as "not endangered". In the federal states of Rhineland-Palatinate , Baden-Württemberg and Thuringia , however, it is considered "endangered" and in Lower Saxony , North Rhine-Westphalia and Mecklenburg-Western Pomerania as "severely endangered".
