Dear Christina,
You can tell by the close set eyes that this Black Horse Fly,
Tabanus atratus, is a male.  You can compare your image to this image on BugGuide.  Only female Horse Flies bite and suck blood.  Males take nourishment from fruit.  According to BugGuide:  “Females feed on mammalian blood, while males, which lack mandibles, feed on nectar and plant juices (Long 2001). This species especially prone to attack cattle and other livestock.”
