The in-nest biologies of Osmia lignaria propinqua Cresson, Osmia californica Cresson, and Osmia montana montana Cresson are, for the first time, described based on information obtained from within observation boxes placed in field and greenhouse environments. Cell construction, provisioning, and egg deposition are described in detail and in a comparative format. Embryogenesis, egg eclosion, molting, immature development, and cocoon construction also are described for each species based on concurrent laboratory studies. The function of head tubercles (malar, labroclypeal, genal) are, for the first time, associated with the nesting biology of Osmia . In addition, courtship and mating, methods of collecting nest materials, fecundity, and voltinism are described based primarily on field observations. Twenty-eight new biological characteristics are recognized as a result of these studies. These particular features distinguish the two subgenera ( Osmia, Cephalosomia ) and three species treated and should, therefore, be incorporated into future biosystematic studies.
