Hey bugman, I thought you might like these photos of a bee killer ( Mallophora leschenaulti) that I came across about a week ago. It was probably the largest robber fly I have ever seen. I posted the pics to bugguide and was given this ID. I hope you enjoy my photos of this impressive insect as much as I enjoy visiting your website multiple times per day!

Belzebul Bee Killer

Belzebul Bee Killer

Hi Michael,
One of our favorite reasons for posting photos of
Mallophora leschenaulti is that the common name is the Belzebul Bee Eater.  There is a long history of associating Satan with flies and the person that gave this adept hunter its common name must have found it to be among the most demonic looking of flies.  While we do not endorse demonizing insects unnecessarily, we are amused by the common name nonetheless.

I saw this guy hang out with his thug friend in my flower garden. Earlier I spotted one attacking one of my Pinevine Swallowtails.

Dear Amy,
The Southern Bee Killer,
Mallophora orcina, is one impressive predator.  These large Robber Flies are adept hunters that take prey on the wing.  We are sorry to hear about your Pipevine Swallowtail.  More information on the Southern Bee Killer can be found on BugGuide.

I got lucky today and this guy landed on the fence right by me to devour his waspish meal. I believe he is a Diogmites salutans. I thought you might enjoy the photo, it was great to get to watch this strange creature. We are in Ocala, Florida and I get a lot of wasps feeding on my Spanish Needles but this is only the second time I’ve seen a Robber Fly.

Dear Jenifer,
Thanks to your photo, it is easy to see how Hanging Thieves in the genus
Diogmites get their common name.  While we cannot confirm the species, you have correctly identified the distinctive genus for this Robber Fly.

Hi Daniel!
Just back from Yellowstone/Grand Teton – a spectacular vacation. I saw lots of beautiful winged creatures, but this little blue-eyed fly caught my attention. I am pretty sure it’s a robber fly, and I am pretty sure it’s clutching some prey. I apologize for the bad photo, but it let me get one shot from a distance before it took off. I hope all is well with you!

Hi Dori,
We cannot say for certain which species of Robber Fly you have photographed, however we do agree that based on images posted to BugGuide, this looks very similar to the members of the genus
Megaphorus.

Hi!
We found this bug, and it seemed to be one body, with two heads. I have never seen anything like this and was hoping you can tell me what kind of bug it is. My email address is [edited for content], as soon as you figure it out please tell me what it is!!
Thank you!

This is the first time I have encountered this insect.
It flew into our cabin & would not leave.
I was scared to mess with it too much because it looks like it could fight back.
After some googling, I am guessing it is a robber fly.
Am I right or wrong?
Thank you.

Robber Fly, we presume

Robber Fly, we presume

Dear Heather,
We apologize for the tardy response.  We spent a bit of time trying to identify your insect, which we also believe to be a Robber Fly, but we were unable to find an identification prior to leaving town for two and a half weeks.  Then time just got away from us and we never created the posting which we have now remedied.  We will send this image to Eric Eaton to see if he can provide any information.
