Mimumesa atratina is a hymenoptera fromthe Crabronidae family .
features
The wasp reaches a body length of 8 to 10 millimeters (females) or 7 to 8.5 millimeters (males). Her body is colored black. The petiolus is longer than the postpetiolus and so are the tibiae of the hind legs. The females have a narrow pygidial field with a smooth center. The species can easily be confused with the other species in the genus Mimumesa .
Occurrence
The species is distributed from northern Spain and Italy to northern Europe, just south of the Arctic Circle, as well as in Asia east to Japan. The species is about to expand its occurrence further. It colonizes various habitats with sandy soils and also occurs in human settlement areas, for example at paving stone joints. The species flies from May to mid-September, forming a partial second generation. It is widespread in Central Europe and is the most common type of the genus Mimumesa .
Way of life
The females lay their nests underground - contrary to what is mentioned in some literature. They reach five to ten centimeters deep in the sand, but sometimes extend further horizontally. Nests built in steep walls bend downwards. A total of four to ten cells are created per nest, each of which is filled with up to 17 dwarf leafhoppers (Cicadellidae) or spur leaf hoppers (Delphacidae). When approaching the nest, the females often land 40 to 70 centimeters in front of the nest entrance and only fly into the nest after a short break. The larvae pupate in cocoons , in which parts of the prey are built.
