Genus: Osmia Panzer, 1806
Subgenus: Ozbekosmia Zanden, 1994
Common name: none
Osmia (Ozbekosmia) are non-metallic bees with pale hairs. They range in body length from 7–13 mm (Michener 2007).
(modified from Michener 2007)
Osmia (Ozbekosmia) may be confused with O. (Tergosmia) due to similar non-metallic and pale-haired bodies, tridentate and medially narrowed female mandibles, and straight apical margins of male S2 and S3 (Michener 2007). Osmia (Ozbekosmia) can be differentiated from O. (Tergosmia) by the produced clypeal margin of female Osmia (Ozbekosmia), the presence of a strong lateral tooth on male T6, and the heavily sclerotized apical projection of T7 (Michener 2007).
Pollen collected from Osmia (Ozbekosmia) avosetta scopal hairs was used to identify host associations (Rozen et al. 2010). In Turkey, O. avosetta rely on Onobrychis viciifolia (Fabaceae), whereas in Iran they rely on Hedysarum elymaiticum (Fabaceae). These bees appear to be specialists on the plant tribe Hedysareae (Rozen et al. 2010).
Osmia (Ozbekosmia) nest cells are lined with two layers of colorful flower petals with a thin layer of mud in the middle (Rozen et al. 2010). The bees use either the whole petal or large pieces of the petals to line the cell walls. Nests are located in barren areas within soil that is loosely compact, fine, and easily crumbled (Rozen et al. 2010). Each nest contained one or two cells (Rozen et al. 2010).
Osmia (Ozbekosmia) is monotypic with one species: O. avosetta (Michener 2007).
There are no known invasives.
