The larvae of Aedes trivittatus may be found any time during the summer following rains, in floodwater pools in meadows, swamps, and woodlands. The females are persistent biters, attacking at dusk and during the daytime, even in bright sunshine, when the vegetation in which they hide is disturbed. (Carpenter and LaCasse 1955:251)
