I saw this flying around our yard yesterday, and dead in our driveway today. I believe it is the red-footed cannibal fly you mention on your page 3 of horse flies. Can you confirm this for me?

Giant Robber Fly

Dear Maggie Bean,
This is definitely a Giant Robber Fly in the genus
Promachus, but since its “feet” are hidden under its body, we cannot say for certain that it is a Red Footed Cannibalfly, but it is in the same genus which is well represented on BugGuide by many similar looking species.
