Distribution. Switzerland (Valais), southern France (including Corsica), Iberian Peninsula ( Spain, Portugal), Maghreb ( Morocco, Algeria, Tunisia). Osmia anceyi seems to be entirely absent from Italy, even in the country’s westernmost parts (G. Pagliano personal communication).

Subspecific classification. The apical margin of the clypeus of females occurring in Morocco, Algeria and Tunisia is slightly less emarginate than in females from southwestern Europe. Based on this difference, Zanden (1994) established two subspecies, i.e. Osmia anceyi anceyi Pérez 1879 distributed in southwestern Europe and O. anceyi biarmica ( Zanden 1994) ranging from Morocco to Tunisia.

Pollen hosts. Oligolectic on Asteraceae (based on 26 pollen loads from 18 different localities in Switzerland, France, Spain, Morocco and Algeria and on field observations). All 26 pollen loads exclusively consisted of pollen of Carduoideae ( Centaurea and/or thistles), suggesting that O. anceyi restricts pollen harvesting to this subfamily. Flower records: Carduus nutans , Centaurea algeriensis , C. calcitrapa , C. jacea , C. paniculata , C. solstitialis , C. sphaerocephala , Onopordum illyricum (label records).

Nesting biology. The nests are built in various preexisting cavities: insect burrows in dead wood, dead hollow plant stems, burrows in the pith of dead stems (e.g. Asphodelus ) excavated by other aculeates (e.g. Ceratina ) or abandoned nests of aculeate hymenopterans in clay walls (Alfken 1928; Torres et al. 1997; Amiet et al. 2004; G. Le Goff personal communication; A. Müller unpublished data). The nests contain up to nine linearly arranged brood cells, which are separated from each other by partitions constructed from mud, which is sometimes mixed with small particles of pith. Coelioxys osmiae Alfken is assumed to be a brood parasite of O. anceyi (Alfken 1928) .
