Hi bug guys,
I came across this fellow on a hike this weekend along the Natchez Trace outside of Nashville, TN. It was buzzing loudly and attempting to fly but clearly has some wing damage and is approximately 1-2in in length. The picture doesn’t capture the pretty blue coloring of it’s eyes. I have lived here for about 8yrs and have never seen this species before.
What is it?

Dear Drew,
This is a male Black Horse Fly,
Tabanus atratus.  While female Horse Flies will bite and suck blood, males of the species feed on nectar.
