These wasps build the brood cells of their nests of moist mud gathered along the water. They attach them to different surfaces, such as rocks, branches and buildings.
Into their already prepared pots, they bring small young spiders. Then each of them lays egg in the cell and closes it with mud. The species, which was brought to Europe from North America, was found for the first time at Sečovlje salt-pans in 1996. In places where it occurs, the numbers of domestic Digger Wasps are usually reduced soon.
