Astata is a genus of digger wasps (Spheciformes) from the Crabronidae family. 76 species are known worldwide, of which about 30 occur in the Palearctic and 17 are also common in Europe. There are three types in Central Europe. The genus is distributed worldwide with the exception of Australia.
features
The genus can be distinguished from the similar Dryudella by a noticeably structured propodeum . The males also have a completely black forehead, in the females the pygidial field is matt black and bordered by curved, small, strong bristles.
Way of life
Males can be observed when they use small stones and the like to sit down, presumably to look out for females. The animals can fly extremely quickly. The females build multi-cell nests in the ground. The prey, bed bugs , is deposited in the cell with the belly side facing downwards, the egg is always deposited on the prosternum under the bug that was entered first and then extends to about half of the abdomen. As with the Philanthinae , the prey is sometimes temporarily stored in the corridor of the nest and only when there are sufficient numbers are the cells made and the prey divided up between them. The anesthetized victims are transported in flight upside down by grasping the tentacles with their mandibles. The prey is additionally supported with the legs.
