Warm open habitats, gardens, rocky places and buildings offering wet mud and protected nest surfaces.
Diurnal; adults visit flowers while females collect mud and hunt caterpillars.
Adults take nectar; larvae consume the paralysed caterpillars stored by the mother.
Solitary potter wasp.
What makes this species remarkable?
A female moulds wet soil into a hardened brood cell, lays one egg and packs the chamber with several paralysed caterpillars before sealing it.
The nest is a complete life-support capsule: after closure, the larva eats the stored prey, pupates and cuts its own exit as an adult.
One monitored Algerian nest was followed for 70 days and ultimately produced four adult females.
