The Balkenschröter ( Dorcus parallelipipedus ) is a beetle from the Schröter family (Lucanidae).
description
The 16 to 32 millimeter long body of the beam grinder is matt dark brown to black. The head is broad. This is much wider in the male than in the female. The head, pronotum and wrinkled wing cover are dotted. The rails of the first pair of legs have several strips and longitudinal grooves on the top. It has ten-link antennae with four end links. Its powerful jaws are sharp and even able to pierce human skin. Overall, the shape is similar to that of the female stag beetle .
Way of life
The beam shredder is both diurnal and nocturnal. It feeds on tree sap, which it licks up, and stays in deciduous forests or orchards with old trees between May and July. There the beetle can often be found in the rotten wood of fallen trees, where it also lays its eggs and where the larvae develop. The larvae pupate after two to three years. The beetles hatch in late summer and still hibernate on site. The beetles do not leave their pupation place until the following spring.
