Habitat and Ecology [top]

Habitat and Ecology:

Osmia versicolor possibly occurs in temperate grasslands, forests (or forest edges) and in Mediterranean-type shrublands, although the habitat has not been described. It nests in empty snail shells of small to medium size with usually several cells per shell. The cell partitions and nest plug are made of chewed leaves without addition of pebbles. The space between the partition of the outermost cell and the nest plug is densely filled with small pebbles, earth crumbs or pieces of dry blades. The closed shells are neither moved nor covered with patches of leaf pulp (Benoist 1931, Westrich 1989, Banaszak and Romasenko 2001, Moreno-Rueda et al. 2008). This species is polylectic, in that it prefers to forage upon a wide range of flowering plants species, with a strong preference for Fabaceae (Amiet et al. 2004, Westrich 1989, unpublished data, A. Müller pers. comm. 2014).

Conservation Actions [top]

Conservation Actions: The species is included in the National Red List of Germany (Critically Endangered; Westrich et al. 2011) and in Switzerland as (Critically Endangered; Amiet 1994). It is unknown whether it occurs within any protected areas. Further research should be conducted to determine the population size and trends, habitat and ecology, and threats to the species.
