The immature stages of oswaldoi are found in the interior, usually in or on the margins of tropical forests, frequently along roads, in cultivated fields or grasslands adjacent to forested areas. They occur in permanent or temporary ground pools, margins of ponds or lakes, swamps, and stream-side pools; the sites most often are found in deeply to partially shadeda reas, less often in full sun. The immature stages are commonly collected in the grassy margins of pools with muddy bottoms. Algae and abundant flotage often are present. The water is always fresh and may be turbid or clear.

Medical Importance:
An. oswaldoi has been experimentally infected with Plasmodium vivax and P. falciparum by, Fonseca and Fonseca ( 1942) in the state of Sao Paulo, Brazil, and by Rozeboom (1942) in Trinidad; however, it has never been found naturally infected or otherwise implicated in transmitting malaria. Deane, Causey and Deane (1948) dissected 540 females from the northeast of Brazil and found none infected with Plasmodium. At present, oswaldoi does not seem to be a vector of malaria.
