The orchard mason bee, Osmia lignaria, is a megachilid bee that makes nests in reeds and natural holes, creating individual cells for their brood that are separated by mud dividers. They are unlike carpenter bees in that they cannot drill holes in wood.

A number of species of Osmia are cultured for use in pollination. Osmia lignaria is a common species used for early spring fruit bloom in Japan and the United States.
