Larvae can be found in bodies of water containing a high degree of organic pollution and close to human habitation. Females readily enter houses at night and bite man in preference to other mammals (Sirivanakarn 1976).

Medical Importance

This species is a vector of avian malaria, a primary vector of Wuchereria bancrofti. Western equine encephalomyelitis and St. Louis encephalitis have been isolated from this species and it has been implicated as a vector of dog heartworm (Carpenter and LaCasse 1955, Sirivanakarn 1976).
