BOB
n.— «But the mason bee earns an “A” for effort from orchardists and gardeners. This native of Washington, common throughout the West, is one of our hardest-working pollinators. Mason bees have a sweet tooth for fruit trees, and for this reason they are often called orchard mason bees. Because of their distinctive color, they are sometimes referred to as blue orchard bees, or BOBs.» —“Gardener’s little helper” by Debbie Cafazzo News Tribune (Tacoma, Washington) Feb. 28, 2009.
