Osmia ribifloris ribifloris
blueberry mason bee
Osmia ribifloris ribifloris is a subspecies of mason bee native to western North America, endemic to regions west of the Mississippi River including Texas, California, and Oregon. It has been developed as a commercially managed pollinator for blueberry crops, particularly rabbiteye and southern highbush blueberries, with 14 years of rearing data documented from the Deep South. The subspecies produces cocoons that can be stored and released for field-scale pollination services.
