I spotted this flying insect on a purple coneflower near an area with man-made ponds and lots of dragonflies, turtles and fish. When the insect flew away, there was a buzzing sound.

Hi. I actually figured out (after much research) that the photo I submitted was of a robber fly (aka assassin fly), Asilidae…and further narrowed it down to a variety of Diogmites. I can’t seem to take it any further, as I haven’t seen any of these with abdomens as long as the one in my photo.
We were away from the office when you wrote, and we are trying to catch up on old mail, posting some of the more interesting images we received in our absence, including yours. Your identification is only partially correct. While this is a Robber Fly in the family Asilidae, it is not a Hanging Thief in the genus Diogmites. It is a Red Footed Cannibalfly, Promachus rufipes, and you can compare your excellent image to the images posted to BugGuide.
