Your letter to the bugman: In case you need another photo… these flies are big. After I saw it was a horse fly, I went back outside and killed it. (Horse farm 0.5mi up the street…)

Thanks so much for submitting your image of a female Black Horse Fly. Female Horse Flies can be identified because of the space between their eyes. Male Horse Flies lack the space. Female Horse Flies are the blood-suckers. Males are harmless.
