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!

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.
