Renter: Existing cavities in the ground (Mavromoustakis, 1948), in general 4-8 brood cells per nest, which are linearly arranged or form clusters depending on the form of the cavity.
Nesting material: The cells are entirely built of leaf pulp. The entrance of the nest burrow (diameter: 8-9mm) is closed by a plug of leaf pulp. (Mavromoustakis, 1948; Pashina, 1948, 1971; Popov, 1967a)
