Osmia lignaria, commonly known as the orchard mason bee or blue orchard bee, [1] is a megachilid bee that makes nests in natural holes and reeds, creating individual cells for its brood that are separated by mud dividers.
Mason bee is a name now commonly used for species of bees in the genus Osmia, of the family Megachilidae. Mason bees are named for their habit of using mud or other "masonry" products in constructing their nests , which are made in naturally occurring gaps such as between cracks in stones or other small dark cavities.
