The black-brown Kurzschröter , Kurzschröter or Kurzhornschröter ( Aesalus scarabaeoides ) is a beetle from the Schröter family (Lucanidae; occasionally as a separate family Kurzschröter , Aesalidae). The species is the only representative of its genus and of the subfamily Aesalinae in Central Europe.
features
The beetles reach a length of 5 to 7 millimeters and have a very shiny, black-brown colored body. Compared to other Schrötern it has a stocky body, which is similar to that of the earth beetles (Trogidae).
Occurrence
The species is distributed from central Europe to western Turkey . In the north, the distribution extends to the North and Baltic Seas and to southern Sweden. Accordingly, it is absent in the British Isles and the main part of Scandinavia, south of the Pyrenees as well as in western France, Denmark and Greece. The beetle prefers deciduous forest areas, especially mixed oak and beech forests, in the lowlands and low mountain ranges.
Way of life
The larvae develop mainly in the rot-rotten wood of oaks and, more rarely, beeches , which are still hard on the outside and are in dense bushes and in damp places. Further food plants are the birch , the sweet cherry and various conifers (pine, spruce, fir). It probably takes one to three years to develop and pupate in the wood. As a rule, the beetles also stay in their foraging and nesting woods in several generations and regular new broods.
The species is rare in Central Europe, it is listed in the Red List of Threatened Species in Germany as "critically endangered" (Category 1), only in North Rhine-Westphalia is the species considered "critically endangered" (Category 2).
