Fabricius' ground beetle ( Carabus fabricii ) is a species of the real ground beetle ( Carabus ). It is named after the Danish naturalist Johann Christian Fabricius .
features
Fabricius' ground beetle reaches a body length of 16 to 25 millimeters and is one of the largest species of beetle in Europe. Its body is copper brown to black glossy and instructs the elytra ( elytra ) and the sides of the neck plate a coppery shimmer on. The point pits of the wing covers are colored green and thus form a clearly recognizable contrast to the basic color. The elytra lie relatively flat on the body, the pronotum and head are built narrow.
Fabricius 'ground beetle differs from the very closely related Creutzer ground beetle ( Carabus creutzeri ) primarily in the length of the first antennae, which in Creutzer's ground beetle is almost three times as long as it is wide and thus significantly longer than that of Fabricius' ground beetle. In addition, the wing covers of Fabricius' ground beetles usually have broad, matt emerald green side edges. The ravine forest ground beetle ( Carabus irregularis ) can be distinguished from both by details of the mouthparts.
distribution
The beetle occurs in the Alps of Germany, Austria and Switzerland as far as French- speaking Switzerland . It can also be found in the Carpathian Mountains .
Way of life
Fabricius' ground beetle lives mainly in upper mountain areas and is classified accordingly as high alpine or montane . Its habitat is in mountain forests, where it can be found in dead wood or under loose bark of lying wood.
Like most large ground beetles, Fabricius' ground beetle is a diurnal predator that feeds primarily on other insects and their larvae.
