Tabanidae
Predators and parasites

Eggs are often attacked by tiny parasitic wasps, and the larvae are consumed by birds, as well as being paratised by tachinid flies, fungi, and nematodes. Adults are eaten by generalized predators such as birds, and some specialist predators, such as the horse guard wasp (a bembicinid wasp), also preferentially attack horse-flies, catching them to provision their nests.
