Hi. Recently, I took a picture of this fly on my car and I’m not sure what kind it is. Most people say it’s a horse fly but I’m not sure. Any idea?

Dear Al,
This certainly is a Horse Fly, and upon scrolling through BugGuide pages, we believe we have correctly identified it as Tabanus stygius. According to BugGuide‘s data, this wide ranging species is found in Ontario. We cannot tell from your image if this is a female or a male as the space between the eyes is not visible, but only female Horse Flies are blood-sucking biters.
