Description

They are very small (1.5–2.5 millimetres or 0.06–0.10 inches long) flies that frequently congregate around the eyes to lap at the fluids. They are primarily a nuisance pest, and do not bite. They have been linked with the spread of bovine mastitis in North America, and in certain tropical regions, they are capable of vectoring disease-causing bacteria (e.g., yaws).^{[citation needed]}

Hippelates pusio is considered to be the vector for anaplasmosis, bovine mastitis, and Haemophilus spp. which cause bacterial conjunctivitis or 'pinkeye'.^[1]

Distribution

Hippelates are Neotropical and Nearctic in distribution.^[2]
