Description:This illustration depicts a dorsal view, i.e., from above, of a Hippelates pusio biting fly, more commonly known as an eye gnat.
H. pusio are known to derive nourishment from eye secretions, and are prevalent during the warm months. Eye gnats have been implicated in playing a crucial role as a mechanical vector in the transmission of Haemophilus spp. organisms responsible for causing outbreaks of seasonal conjunctivitis. Gnat-borne transmission of this disease has been documented in animal studies.
