American Horse Fly

Tabanus americanus

This fly was named after the female of the species, which feeds on the blood of large animals such as horses. Silent in motion, the female lands on its prey unnoticed, delivering a painful bite with knife-like mouthparts. The male horse fly eats pollen and nectar.
