features

The bees are 7.5 to 11 millimeters long. The body of the females is colored black, their legs are dark brown to black. The third antenna segment is more or less colored red. All tergites have two white hair spots each. The scutellum has long, narrow, rounded thorns on the sides. The sixth sternite has claws. The males look similar to the females. On the third to fifth sternite on the rear edge they have a row of bristles that stand up like a comb and are curved at the end.

Occurrence and way of life

The species is distributed from Spain via France, Italy, Austria (Burgenland, Lower Austria, Styria) and Hungary to Bulgaria. It was also found in Switzerland (Valais, until 1942). The animals fly from late July to mid-August. They parasitize Tetralonia macroglossa and probably also Tetralonia dentata and Tetralonia salicariae .
