Unusual fly
Could you identify this fly? I caught it tonight flying around my sister’s room, freaking her out as if it was going to attack her. I tried searching google for it, but there seems to be a lack of information on flies. All help is greatly appreciated.

Hi Dave,
All of the Green Horse Fly images on BugGuide came from North Carolina, Georgia and Florida. Green Horse Flies are in the genus Chlorotabanus.

    We just caught the first one I’ve ever noticed in Kentwood, Louisiana. Are they common here and i just don’t know it?

    I just got one in my kitchen. Southeastern Ohio July 14, 2015. I have never seen one before.

      If you identification is correct, this is a more northern sighting than any reported on BugGuide.

        I first thought it was a white bee. I stunned it with a fly swatter and my daughter in law took a picture of it. She used an app on her phone to find out what it was. She found several websites with pictures identifying it. This was a Green Horse Fly.

    I’m 61 and have lived in Charleston, SC all my life and there is one in my car as my granddaughter is driving us. I’ve never seen one here before. I’m not going to kill it, but help it get out as soon as we get to the house. Weird looking!

    I found one of these in Walton, West Virginia. Pretty northern for this tabanid, apparently.
