[3][4][5] It has a wide range of geographic distribution that stretches from Mexico and Argentina but it has also been found to populate in areas affected by deforestation and environment changes due to humans.

Due to the fact that mosquitoes rely on the surfaces of stagnant water or areas with regular flooding as breeding grounds for their eggs and larvae,[5] the annual density of the A. darlingi population is dependent upon the availability of larval habitats.

[3] During the wet season, riverine areas are often abundant with mosquitoes and densities are higher in these after the peak of rainfall.

[7] Oppositely, in drier inland areas that are usually further from rivers and coexisting with the affects human disturbance, a peak of mosquito density may occasionally occur in the dry season in areas restricted to man-made dams and stagnant puddles.

[7] In its native range A. darlingi larvae are found by Manguin et al 1996 and Rozendaal 1992 to inhabit littoral, riverine, and backwater bodies.
