I live in Southwest Louisiana and was tending to one of my flower beds today on August 10, 2014 and ran across this bug grooming itself on a coneflower leaf. Could you please identify it for me? I was not sure if it is some sort of horsefly, wasp, or something totally different.

Dear Lyndsey,
This is a Soldier Fly, possibly
Odontomyia cincta based on images posted to BugGuide.

Thank you so much for identifying this intriguing fly so quickly. I had trouble finding any images at all until you identified it.
Sincerely,
Lyndsey

Hello,
The attached picture looks like a very large bee, but it has long legs, flies, has a furry ruff around it’s neck and was on my green car side view mirror the other day. I’ve never seen anything like it.

Hi Marisa,
This is the fourth image we are posting today of a Red Footed Cannibalfly, a large predatory Robber Fly, including one image of a mating pair of Red Footed Cannibalflies.
  Add to that two images of Hanging Thieves, another type of large Robber Fly, and that makes a total of six Robber Flies posted today.  We are declaring today the Day of the Robber Flies.

Hello. Live in Columbia MD. Saw these two on my wood deck. When I took their picture they buzzed off. It’s summer here.

Hi Lisa,
This is peak season for large Robber Flies like these mating Red Footed Cannibalflies.  This is the fifth posting today to our site of Robber Flies and the third for this particular species, the Red Footed Cannibalfly,
Promachus rufipes.

I saw this strange bug in the backyard. It has a body shape like a dragon fly, but there only seem to be two small wings and the eyes and mouthparts don’t look typical for a Dragonfly. What would you say it is?

Hi Chris,
We have been deluged with Robber Fly requests this morning, and your individual is a Red Footed Cannibalfly.

I found this bug 3 feet outside my apartment. I live in Lewisville, Texas. I took this picture on August 8, 2014. I really want to know if this bug is dangerous. The rail it is sitting on is about an inch and a half thick. It’s really intimidating. I got as close as I could without making it fly off. I hope it will be enough to identify this bug.

Hanging Thief

Hanging Thief

Dear Any,
This seems to be “the day of the Robber Flies” as this is the third image of a Robber Fly we are posting this morning.  This particular Robber Fly is a Hanging Thief in the genus
Diogmites.  They are stealth predators that generally pluck their prey out of the sky, and their prey often includes large flying insects like wasps and bees.  Robber Flies are not aggressive towards humans, but we imagine if someone was foolish enough to try to capture one by hand, a bite might result.  Texas is home to numerous species of large Robber Flies.  With a bit of imagination, and a slightly different camera angle, a “creative” photographer could take an image that appears as though this individual was waiting to prey upon a luckless human emerging from that parked car, but that would be an example of phantasmagoria. 

Thank you very much for the information. I can rest easier knowing that this bug won’t come after me. I like them a whole lot more knowing they will eat bees and wasps, as I am allergic to their stings. I lived my whole life in Texas but this was the first time I had seen a Robber Fly. A person screaming at the fly in the photo would have been epic. Who knows. Maybe another one will land on the railing. :)

This insect has been hanging around our patio — first seen sitting on a concrete block under a set of wooden steps that lead down to our patio, then the next morning, on the patio itself, about 2 feel from first location — and it has me stymied. About 2 1/2 long, large black eyes, yellow and black stripes. Doesn’t move when approached, or react to loud noises. What the heck is this?

Red Footed Cannibalfly

Red Footed Cannibalfly

Dear Joan,
This predatory Robber Fly looks like a Red Footed Cannibalfly,
Promachus rufipes, and we believe it is probably perfectly fine and behaving like the stealth predator that it is.  Like many predators, Red Footed Cannibalflies are territorial, and when the hunting is good, they will remain in the area.  Large Robber Flies are among the few predators that will attempt to prey upon stinging wasps, and perhaps there is a nearby nest of hornets or paper wasps that is supplying this individual with a ready source of food.  Robber Flies take prey on the wing, and when a likely source of food flies by, we predict this individual will take off and snatch an unsuspecting wasp or other insect out of the air.  Robber Flies are not aggressive toward humans, but we would caution you to refrain from trying to catch one with your hands as that might result in a bite, though we have never received a report of a person being bitten by a Robber Fly.

Thank you so much!  My granddaughter will be thrilled to learn this, and I am relieved to know about it’s peaceful character.  Yes, there are wasps about – I’m happy to have him here!
Joan Garrity
Serenity, courage, wisdom.
