Your letter to the bugman:  I took pictures of two of these very large black bees/flies this morning. I noticed them when refilling a water saucer in a shady woodland setting. Is this a beneficial creature for my certified wildlife habitat, or should I be worried for wood damage in the area?

Belzebul Bee-Eater

Dear Curious Kat,
This is definitely a predatory Robber Fly and not a Bee.  The white “cheeks” and yellow band on the abdomen are good indications this is a Belzebul Bee-Eater,
Mallophora leschenaulti, which is pictured on BugGuide.  According to BugGuide:  “has been reported to attack and kill hummingbirds” but we suspect that is a very rare occurrence.  In our opinion, though they are known to prey on Bees, the Belzebul Bee-Eater would be a beneficial creature in your certified wildlife habitat as it is a native species.

  1. Belzebub means lord of the flies in Hebrew. If the flies are going to have a lord, a great big robber fly like this one seems like a good choice.
