Blue Orchard Bee

While working on the back porch on 27 March 2021, I found s small, black bee. iNaturalist had no trouble identifying it as a Blue Orchard Bee, Osmia lignaria. This bee nests in reeds and natural holes, but, unlike carpenter bees, it does not drill its own cavities. Blue Orchard Bees are common pollinators in the early spring—the species flies during colder and cloudier days than many other bees. Commercial orchards and gardeners buy these bees and bee houses. These bees seldom sting and tend to be solitary. The bees do require cold winters to survive and are found across much of North America.
