Nesting biology-Nesting site: Preexisting cavities: insect burrows in dead wood. Nesting material: Cell partitions made of mud, sometimes also of leaf pulp. Nest plug made of small stones, masticated leaves and pieces of rotten wood; the particles in the end plug are not cemented together and pieces can easily fall off. (Amiet et al., 2004; Frey-Gessner, 1880; Friese, 1923; Giraud, 1861; Grünwaldt, 1939; Käpylä, 1978; Stoeckhert, 1933; Westrich, 1989)

Flower preferences: Polylectic with a preference for Fabaceae; additional pollen sources include Ranunculaceae (Westrich, 1989; A. Müller, unpublished, based on 15 pollen samples from 4 different localities and on field observations).
