Crabro cribrarius is a Hymenoptera from the family of Crabronidae .
features
The animals reach a body length of 11 to 18 millimeters (females) or 9 to 17 millimeters (males). Their body is black and yellow in color. The mesonotum is conspicuously fissured. The males have widened antennae and shield-shaped tibiae on the front legs. These are brownish in color and lightly spotted.
Occurrence
The species occurs in Europe and Asia as far as Korea. It colonizes various habitats from dry sandy areas to forest meadows and is also found in settlement areas. The animals fly from early June to early September. The species is common in Central Europe.
Way of life
The females of Crabro cribrarius lay their nests 15 to 20 centimeters deep, mostly in the sand in hidden places. At the end there is one cell, and another of the two to four cells is located at the end of side corridors. The literature states that the species also nests in dead wood, which is probably incorrect. The Imagines but occasionally stay in it. The brood is supplied with medium to large predator flies , blowflies and horseflies . These are captured by the females directly in flight. Five to eight flies are introduced per cell. The adults themselves feed on nectar and are often found on umbellifers . When mating, the male places his shield-shaped widened tibia over the eyes of the female.
