Tiger Bee Fly


Nothing to worry about, though it reminds me of a Horsefly. Actually something to cheer about. This is a Tiger Bee Fly (Xenox tigrinus). It doesn’t show any aggression toward humans. No stinging. No biting.

Measuring in at one-half to three-quarter inch long, the Tiger Bee Fly is an insect of the family Bombyliidae (bee flies), which is native to the eastern United States and southern Ontario. It’s a wonderful pollinator in our gardens with an extra SUPER benefit that is brought to our homes and yards. The female Tiger Bee Fly lays her eggs near the entrance to Carpenter Bee nests. As her larvae hatch they enter the Carpenter Bee nests and eat those larvae. A parasite of Carpenter Bees! I must put out a sign saying, “Welcome Tiger Bee Flies!”
