The larvae and other juvenile stages of
An. nuneztovari have been collected in fresh water exposed to full sun or in partial shade in marshy areas, ponds and lakes, permanent or temporary ground pools, tracks of animals and wheels, and along stream margins. Adult
An. nuneztovari mosquitoes have been found in the interior of forests, in clearings within the forest, and in areas of secondary growth such as around villages. Their occurrence near villages increases their importance as
vectors of human disease. ==Medical importance==
