Orchard mason bee

Osmia lignaria

''Osmia lignaria'', commonly known as the orchard mason bee or blue orchard bee, is a megachilid bee that makes nests in reeds and natural holes, creating individual cells for its brood that are separated by mud dividers. Unlike carpenter bees, it cannot drill holes in wood. ''O. lignaria'' is a common species used for early spring fruit bloom in Canada and the United States, though a number of other ''Osmia'' species are cultured for use in pollination.

Defense

Orchard mason bees, like all mason bees, are very shy and only sting if they perceive serious danger. They do not attack to defend themselves. The stinger is actually an egg guide. Because of their docile behavior, mason bees are preferred by people who desire pollination in urban settings.
