Liris niger is a hymenoptera fromthe Crabronidae family .
features
The wasp reaches a body length of 9 to 12 millimeters. Their body is black in color and has relatively long hind legs. The face has at the edges of the compound eyes a longitudinal bead. The species can be confused with various wasps (Pompilidae).
Occurrence
The species is widespread in southern Europe, southern central Europe and Morocco and inhabits dry and temperature-favored habitats. The time of flight of the species is unknown. In Germany, it has been found in the Kaiserstuhl in Baden-Württemberg , among other places , but the last find dates from 1967.
Way of life
The females show a similar breeding behavior as the closely related Larra anathema . The brood is mainly supplied with real crickets of the genus Gryllus . The female only stuns the crickets lightly with one prick and either uses existing ground cavities as a nest, such as abandoned bee nests or cracks in the ground, or, if there is no one, digs a nest passage about 10 centimeters deep. Usually only one cell is created, in which, however, several crickets can be placed.
