Nesting biology-Nesting site: This species appears to use both preexisting cavities and stone surfaces as nesting sites. Preexisting cavities: abandoned cells in exposed nests of Megachile (Chalicodoma) parietina; small cavities and holes in rocks or stones containing mostly 1, rarely up to 4 cells. Exposed nests: upper surface of a stone with 2-3 cells. Nesting material: Cell partitions are made of chewed leaves intermixed with small pebbles or occasionally of chewed leaves only. The nest plug is made of two to four layers of small pebbles (1-2mm in diameter) cemented together with leaf pulp, its convex surface expanding 2-3mm to the adjacent rock surface. Cells of exposed nests are entirely constructed from very small pebbles cemented together with chewes leaves and eventually covered by an additional layer of the same material. (Benoist, 1931; Ferton, 1901a, 1914, 1920; Mavromoustakis, 1948c)

Flower preferences: Polylectic; pollen sources recorded so far include Fabaceae (e.g. Lotus), Echium (Boraginaceae) and Lamiaceae (A. Müller, unpublished, based on 10 pollen samples from 8 different localities) .

Nesting biology-Nesting site: Preexisting cavities: insect burrows in dead wood. Nesting material: Cell partitions and nest plug are made of chewed leaves. Females were also observed to collect pebbles and mud on the ground, indicating that this species occasionally uses a mixture of leaf pulp and pebbles as nest building material as many other Pyrosmia species do or that the pebbles are used to barricade the nest entrance, a behaviour that is known from other Pyrosmia species as well. (Benoist, 1931; Ferton, 1895; G. Le Goff, personal observation; A. Müller, personal observation)

Flower preferences: Polylectic with a preference for Fabaceae; additional pollen sources include Echium (Boraginaceae), Lamiaceae (Lamioideae, Nepetoideae), monocots and Cistaceae (A.

Nesting biology-Nesting site: Preexisting cavities: insect burrows in dead wood and drilled borings in wooden blocks; hollow stems (e.g. Rubus, Sambucus) and drilled borings in pithy stems; cavities within abandoned galls of Andricus kollari with 10-24 cells and of Cynips argentea with 10-12 cells. It is unclear whether the females are able to gnaw burrows of their own in the pith of stems or galls. In galls, pith is sometimes removed to accomodate the cells, which are irregularly arranged within the cavity of the galls. Nesting material: Cell partitions are made of chewed leaves. The nest plug consists of three to four partitions of leaf pulp separated by 0.5-1mm from each other. When nesting in pithy stems, pith is sometimes incorporated into the leaf matrix of partitions and plug. In the subspecies lapidistructor, the cell partitions are built of small pebbles cemented together with leaf pulp. (Banaszak and Romasenko, 2001; Benoist, 1931; Ducke, 1900; Enslin, 1925, 1933; Ferton, 1920; Friese, 1911b, 1923; Latreille, 1811; Westrich, 1989)
