Entomognathus brevis is a hymenoptera fromthe Crabronidae family .
features
The wasp reaches a body length of 4 to 6 millimeters (females) or 3 to 5 millimeters (males). The species can be confused with several species of the genus Lindenius , which, however, differ from it by their hairless compound eyes . The lobe on the pronotum is yellow, the mandibles have a base tooth.
Occurrence
The species is distributed from North Africa across Europe to Japan. It colonizes various dry habitats and temperature-favored forest edges with soils of a cohesive consistency. They sometimes also occur in human settlements and have been proven up to 750 meters above sea level. The animals probably fly in two generations from May to September. The species is common, but is rarer in the north.
Way of life
The females usually build their nests on slightly sloping places with little or no vegetation in the clay or gravelly sand. The nest consists of a main passage over 10 centimeters deep, from which side passages branch off to three to ten cells. Often the nest entrance is provided with a short chimney made of the ground. The brood is supplied with flea beetles (Alticinae) or leaf beetles from the subfamily Cryptocephalinae , with 16 to 26 beetles being entered in each cell. The prey is transported in flight and held in place with the middle pair of legs. The wasps' flight is very fast and there are abrupt changes of direction.
