description Osmia ribifloris Overview
Osmia ribifloris is a solitary mason bee native to western North America. It nests in existing cavities rather than living in large social colonies, and females construct and provision their own brood cells. The species commonly gathers pollen from manzanita and other shrubs in the heath family, and its ability to forage in cool conditions has prompted research into its use as a managed pollinator of commercial blueberries.
