Trypoxylon is a genus of digger wasps (Spheciformes) from the Crabronidae family. There are 16 species in Europe.
features
The digger wasps of the genus Trypoxylon have a characteristically elongated, slender, black body. The inner rims of the eyes are strongly kidney-shaped. The animals only have one submarginal cell. Species identification is sometimes difficult.
Way of life
In Central Europe, the females build their nests in hollow or medullary stems, in abandoned bores in the wood or in abandoned hymenoptera nests in loess or clay walls. The individual cells are sometimes of different lengths. They are separated from each other by earth or clay. The last cell is always bordered by an empty cell, which presumably serves to protect against parasitoids . The brood is fed with several small spiders. There are North and Central American species that create tubular clay nests in sheltered places. These can be up to 63 centimeters long. In some species the male helps the female build nests. It guards the nest when the female flies out, helps with the construction and closing of the nest, hauls construction material, takes over the prey hunted by the female and brings it into the nest. Female offspring have an increased need for food. Due to the longer provisioning phase, these nests are more sensitive to parasitoids, which is why the help of the male is particularly important here. Nests in stems can be easily recognized by their brown color and the black droppings at the end. There are a number of non-specific parasitoids such as wasps , parasitic wasps and flesh flies that parasitize these grave wasps.
