The piebald wasp ( Deuteragenia variegata , syn .: Dipogon variegatus ) is a hymenoptera from the family of the wasp (Pompilidae). It occurs in Europe and North Africa.
features
Piebald wasps are uniformly black colored wasps with a body length of 5 to 10 millimeters. It is named after the conspicuously drawn forewings, which have a white spot at the tip, in front of which there is a broad dark brown band. In front of this lies a narrow, translucent bandage and in front of it another, very narrow, dark band.
Occurrence and habitat
The pied wasp is found in large parts of Europe including Madeira, as well as in North Africa and the Middle East . It is distributed almost all over Germany, but no specimens have been found north of Berlin. In the Alps it can occur up to 1700 m above sea level in heat-favored places.
The species is particularly warmth-loving, even more so than the related species Deuteragenia bifasciata . It has a clear focus of distribution in man-made cultural landscapes such as in abandoned vineyards or orchards . There it is mainly to be found on dry stone walls, but it also inhabits forest edges or semi-arid grassland with rocks and stones.
Way of life
The species occurs mostly in low population density. They mainly prey on crab spiders of the genera Thomisus and Xysticus , as well as real sack spiders ( Clubiona ). These are stored in various types of existing cavities, for example in holes in stone walls or rocks. No nests of the pied wasp have been found in dead wood, although they sometimes stay there to sunbathe or hunt for spiders. Sometimes the abandoned nests of the Tönnchenweg wasp and their relatives of the genus Auplopus in snail shells or under rocks are reused or existing ones broken up. One to three brood cells , each with a spider, can be created in a cavity , which are then closed with earth and cobwebs . To sweep up the cobwebs, the females have genus-typical sweeping bristles on the lower jaw .
