The bazaar fly or eye-seeking fly, is a close relative of, and very similar in appearance to, the housefly ('Musca domestica'). It is found in tropical and subtropical Africa, Asia and the Pacific region. It breeds in excreta, especially human faeces, and is the main insect vector of trachoma, a major cause of blindness.

This fly lives in close proximity to humans; it probably coevolved with humans in Africa, spreading with them to other parts of Africa and Asia. It is not found in the Americas. Bazaar flies are a nuisance, disturbing people at leisure and at work, but they are principally disliked because of their habit of settling on people's faces (particularly around the eyes) and on sweaty skin, seeking out bodily secretions and suppurating wounds.
