Tachysphex obscuripennis is a grave wasp from the family of Crabronidae .
features
The animals reach a body length of 7 to 11 millimeters (females) or 5.5 to 9 millimeters (males). The base of their abdomen is colored red. The rails ( tibia ) of the front legs are colored yellow-brown in front. The hair on the propodeum is directed backwards. Males often have golden hair on the clypeus .
Occurrence
The species is spread across Europe and Turkey east to Lebanon. It colonizes open, sandy habitats with favorable temperatures. The animals fly in one generation from late May to August. The species is widespread in Central Europe.
Way of life
The females of Tachysphex obscuripennis lay their nests five to six centimeters deep in the sand. Only one cell is created per corridor. The brood is supplied with two to three cockroaches , mainly with common wood cockroaches ( Ectobius lapponicus ). These are dragged to the nest by the feelers on the floor. Often the legs and antennae are bitten off before they are brought into the nest.
