Your letter to the bugman:  Is this a horsefly?
How you want your letter signed:  uh

Deer Fly

Dear uh,
This is a Deer Fly, not a Horse Fly, but they are in the same family Tabanidae, so they share many similarities.  We believe your individual is in the genus
Chrysops, and according to BugGuide:  “100 spp. in 2 subgenera in our area.” Alas, we haven’t the necessary skills to provide a conclusive species identification.
