Hello Daniel,
I thought I’d add to the growing collection of Black Horse Fly pictures. Seems that they are prolific this year! This one is a little over one inch long, and from earlier posts, I think is a female. If so, and the biting sex, I’m glad she was more interested in the top of my grill than in me.
Keep up the great work! It is amazing, entertaining, and informative.

Hi Bob,
As your email indicates, your specimen of a Black Horse Fly is a female as evidenced by the space between her eyes.  This is an excellent companion photo to the one we just posted a few hours ago of a male.
