The barrel wasp ( Auplopus carbonarius ) is a hymenoptera from the family of the wasps (Pompilidae). The species is common and not endangered.
features
The female, completely black colored animals reach a body length of 7 to 10 millimeters, the males are somewhat smaller. The males have a small white point at the back of the outermost tergum and two white stripes next to each eye in the front. They have shorter bodies but longer legs than most species in their family. What is striking is the abdomen , which is tapered in the front like a stem , which is clearly separated from the thorax . The species is easy to distinguish from other wasps. The second Central European species of the genus, Auplopus albifrons , differs well from the barrel wasp due to its red-colored abdomen.
Occurrence
The species is common everywhere in Central Europe , but in low population densities. It populates walls and house walls in the human environment, but also occurs in open terrain. The flight time is from June to August.
Way of life
Unlike the other native species of the common wasp, the females of the barrel wasp do not build their nests in the ground, but make small, barrel-shaped brood cells, about 8-10 by 4-5 millimeters in size, slightly flattened on one side, from clay. These are about under wooden boards or in other hiding places, e.g. B. also attached behind books on a bookshelf and in empty snail shells. As food for their larvae , the wasps hunt bag spiders and flat-bellied spiders , in which in the large species mostly all or at least many legs are severed. For transport, the prey is not grabbed by the hips, as is customary with other species in the family, but by the spinnerets . Then the spider is usually transported forward, only being pulled in difficult-to-negotiate places. Downward flight jumps can also be made. Several meters on a vertical house wall can be overcome without any problems.
