Horse flies are large bloodfeeding insects from the family Tabanidae. Unlike mosquitoes, these flies inflict an immediately painful bite. Horse flies are typically encountered in outdoor situations- especially near livestock, and can be identified by their distinctive outward-extending antennae and their large eyes that are often brilliantly colored. The eyes of male horse flies are holoptic- meaning that they occupy most of the head and actually touch in the middle (the specimen in the picture is a female).
