Occurrence
The species occurs in North Africa, Europe and east to the Far East. In the south they are mainly found in the mountains. It colonizes various sunny habitats with sufficient nesting opportunities. The animals fly from early May to mid-August. They can be found widespread in Central Europe.
Way of life
Ancistrocerus oviventris is the only species of the genus that builds its nests from mortar on stones, rocks or walls. Several cells are created, which are then covered with a layer of clay. The brood is supplied with caterpillars of smaller butterflies and larvae of leaf beetles and weevils . The species is parasitized by the common golden wasp ( Chrysis ignita ) and by Chrysis ruddii .
