Sometimes called “water bees” or “water wasps,” backswimmers are predaceous and can deliver a painful bite if mishandled. True to their name, they swim belly-up, and their backs are keeled like a boat, which makes back-swimming easier.
Bald-faced hornets are fairly large social wasps. They are mostly black, with white or ivory markings on the face, thorax, and toward the tip of the abdomen. They make large, rounded, papery, gray nests, usually in trees and shrubs.
Resembling bees, or sometimes big, fuzzy mosquitoes, bee flies are a family of true flies and are not bees at all. Lacking the ability to sting, their bee mimicry helps them avoid many would-be predators.
