Species-specific Diagnostic Characters, Adult Stage

Bionomics

The larvae are found in clear seepage water, in roadside pools, in rice fields, and in other similar habitats. Pools that are sunlit, at least part of the day, seem to be preferred, although larvae are occasionally found in rather densely shaded pools. Heavy production of larvae often occurs in matted algal growths in water along the margins of rice fields. The females enter houses readily and feed on man. They are more active at dusk and during the night but occasionally do attack man during the daylight hours in dense shade or on cloudy days. (Carpenter and LaCasse 1955)

Medical Importance

It is the principal vector of malaria in the arid and semiarid western United States. (Carpenter and LaCasse 1955)
