Liohippelates collusor
(Townsend, 1895)
eye gnat
Liohippelates collusor is a of gnat in the Chloropidae, recognized as a significant pest of humans and animals in the United States since the 1930s. Along with Liohippelates pusio, it has been the focus of extensive research on , , and management. The species causes considerable discomfort and stress through persistent attraction to eyes, wounds, and body openings, and may transmit . Its biology and have been well studied in agricultural systems, though its ecological roles in natural remain poorly documented.

Identification
Eye gnats in the Liohippelates are small flies that require close examination for -level identification. L. collusor is distinguished from the closely related L. pusio through morphological features of the male genitalia and subtle differences in chaetotaxy; accurate identification typically requires dissection and comparison with reference specimens.
