The larvae of Aedes taeniorhynchus develop mostly in salt marshes in coastal areas and occasionally in near-by freshwater pools. They have been found also in inland brackish-water swamps, particularly in oil fields, in areas far removed from the coast. The species reaches its greatest abundance along the coastal Caribbean region. The females are persistent biters and will attack anytime during the day or night. The adults rest in the vegetation during the daytime and will attack anyone invading their haunts, even in bright sunlight. They are strong fliers and often migrate in large numbers to communities where they become serious pests, even many miles from the salt-water marshes. (Carpenter and LaCasse 1955:229)
