Aedes scapularis is found at low to moderate elevations throughout most of tropical and subtropical America. It breeds in a wide variety of temporary or semipermanent freshwater situations, primarily temporary rain-filled or stream overflow pools but including pond and swamp margins, rockholes and crabholes, in either sun or partial shade. Females of scapularis attack man readily, and though primarily crepuscular, will bite anytime they are disturbed. (Arnell 1976:61)

Medical Importance

At least 15 viruses having been isolated from Aedes scapularis including yellow fever and venezuelan equine encephalitis (VEE) viruses and it also appears to be a vector of Bancroftian filariasis. (Arnell 1976:9)
