I found this large fly sunning itself on my deck umbrella this afternoon here in NY’s lower Hudson Valley. It’s body is shaped like a horse fly, but it’s markings do not match up with any horse fly pics that I’ve found. It is over an inch long in length. Is it a horse fly?
Signature: Don’t Bite Me
This certainly is a Horse Fly, and she does appear to be a female because of the space between her eyes. Only female Horse Flies bite and feed on mammalian blood. We believe we have correctly identified your Horse Fly as Tabanus trimaculatus based on photos posted to BugGuide.
