Distribution. From eastern Austria, southern Czech Republique, Slovakia and Hungary over southeastern Poland and Romania to southern Ukraine and southern European Russia; from Italy and Slovenia over the Balkan peninsula (Croatia, Serbia, Montenegro, Macedonia, Albania, Greece including Crete, Bulgaria) and Turkey to the Caucasus (Armenia) and central Iran; from Turkey over the Levant (Syria, Israel and Palestine, Jordan) to northern Egypt. The westernmost record is from Mondovi in Italian Piemonte province (G. Pagliano personal communication), the northernmost from Uherské Hradiště in southern Moravia, the southernmost from Cairo in northern Egypt and the easternmost from Komehr in Iranian Fars province. The species’ occurrence in Turkmenistan, Mongolia and the Russian Far East as reported by Romankova (1995) appears to be doubtful and needs verification. Osmia bidentata seems to be entirely absent from France, the Iberian Peninsula and the Maghreb, where it is replaced by O. anceyi as already assumed by Tkalců (1979).
Subspecific classification. The metasomal scopa of females occurring on Lesbos, in Turkey, Iran, the Levant and Egypt is whitish rather than yellowish-red as in females of the more western populations and of the Caucasus. Based on this difference, Tkalců (1979) established two subspecies, i.e. Osmia bidentata bidentata Morawitz 1876 distributed mainly in Europe and O. bidentata pallens (Tkalců 1979) ranging from easternmost Europe over Turkey eastwards to Iran and southwards to northern Egypt.
Pollen hosts. Oligolectic on Asteraceae (based on 62 pollen loads from 27 different localities in Italy, Austria, Hungary, Macedonia, Greece, Turkey, Syria, Israel and Jordan and on field observations). All loads exclusively consisted of Centaurea pollen except for two loads that additionally contained moderate quantities of thistle pollen, indicating that O. bidentata most probably restricts pollen harvesting to the subfamily Carduoideae (Fig. 3). One load contained small amounts of Onobrychis pollen (Fabaceae) beside Centaurea pollen, suggesting that the females very rarely also exploit pollen hosts other than the Asteraceae. These findings are in contrast to Güler & Sorkun (2007), who assume O. bidentata to be polylectic, harvesting pollen from flowers of eleven plant families. Flower records: Carduus spec., Centaurea stoebe (Tkalců 1974a); Arctium, Carduus spec., Centaurea iberica, C. spinosa, Cirsium spec., Onopordum spec. (label records).
Nesting biology. The nests are built in various preexisting cavities, such as insect burrows in dead wood, dead hollow plant stems (e.g. Phragmites) or cavities in the soil (Popovici-Baznosanu 1909; Banaszak & Romasenko 2001; A. Müller unpublished data), possibly also in abandoned nests of aculeates in loess scarps (H. Wiesbauer personal communication). They contain 1–11 linearly arranged brood cells, which are separated from each other by partitions made of mud. In Phragmites stems, the entire brood cells including their walls may be constructed from mud. The nest is sealed by a one-layered wall of mud at its opening. The space between the outermost cell and the nest plug is 1.5–5 cm long and usually empty, but is occasionally divided up by an additional wall of mud. Osmia bidentata overwinters in the prepupal stage (Popovici-Baznosanu 1909).
