Found this guy in the first half of August in southeast Michigan. It landed on my car in a rural area, with fields, woodlands, marshlands, and a small river all nearby. It was fairly large, about an inch long or more. I spent years of my childhood exploring the area and have never seen anything like it.

We believe we have properly identified your Horse Fly as
Tabanus sackeni based on images posted to BugGuide.  It appears that your specimen is a female because of the space between her eyes.  Like Mosquitoes, Female Horse Flies bite while males do not.

    My instinct told me it was a horsefly… but I didn’t know what to think, as all previous horseflies I’d ever seen were the black horseflies.

    Thanks for the identification!
