Good morning. A friend took the attached photo earlier this week. and has given his explicit permission for me to do with it what I want, including sharing it/using it. Our community is in the North Georgia mountains, and my friend’s home is located in the lower elevations of the neighborhood, adjacent to the golf course.
There have been a lot of yellow-jackets in the area this year, so we’re happy that something might be attacking them. But, what in the heck is that big something?
Thanks in advance for any assistance you are able to provide.

Dear Edie,
The predator in the image is a Red Footed Cannibalfly, a large species of Robber Fly.  While Robber Flies might bite a person who carelessly tried to handle one, they are not aggressive towards humans.  The unnatural position of the wings of the Red Footed Cannibalfly in your image is somewhat disturbing, leading us to speculate that it is no longer alive and possibly the victim of Unnecessary Carnage.

I actually found out what this guy was from your website when I first photographed it in 2013. Haven’t seen it since, until yesterday. First photo from 2013, second from yesterday, 8/24/2016. They seem to like being photographed, quite the posers!

Red Footed Cannibalfly

Red Footed Cannibalfly

This large Robber Fly is commonly called a Red Footed Cannibalfly or a Bee Panther since it frequently preys upon bees and wasps that it catches on the wing.

I had an interesting visitor in the drive through at McDonald’s today. A large flying insect flew in my car window. I have never seen anything quite like it, so I started taking pictures of it with my cell phone. It landed on my cell phone case and stayed there, so I popped my cell phone out of the case and took several one-handed closeups. It seemed quite content to model for me and flew away when I was done.

Hanging Thief

Hanging Thief

Dear Crystal,
This is a predatory Robber Fly in the genus
Diogmites, a group known as Hanging Thieves because they frequently hang by one leg while eating.  Hanging Thieves are not aggressive toward humans, but they are capable of biting if they are carelessly handled, but that would have required your son catching one and getting bitten.  We do not believe a Hanging Thief is responsible for the stings your son received.

Thank You,

Dear banjodan,
These are mating Giant Robber Flies or Bee Killers in the genus
Promachus, a group that includes the Red Footed Cannibalfly.  We turned to BugGuide to see if we could find a species match for you, and we were surprised to find your image which was submitted to them last week.
