The blunt speed predator ( Tachyporus obtusus ) is a beetle from the family of the short-winged species (Staphylinidae).
features
The beetles reach a body length of 3.5 to 4 millimeters and, like the other representatives of the genus Tachyporus, have a conspicuously pointed abdomen . Your head and pronotum are colored reddish brown. The front half of the shortened wing ( elytra ) and the directly adjacent edge of the pronotum are black, the second half is also red-brown in color. The black part can be divided into a middle and two side parts. There are also individuals in whom the middle of the pronotum and the head are darkly colored. The abdomen, which is bristled with several thick hairs, is predominantly reddish-brown in color, only the fifth and sixth abdomen segments are black. The last limb of the palps is thin and elongated, and longer than the width of the preceding limb.
Occurrence and way of life
The animals occur in the Palearctic from northern Spain , east to Siberia . They are also found in the British Isles . The northern limit of distribution is roughly the Arctic Circle . They live under leaves and moss on rotting plant material. They occur in forests, fields and meadows from the plains up to an altitude of about 2000 meters. But they can also be found in dry biotopes. The adults appear from late summer or early autumn and are very common. They overwinter on moss-covered trunks.
