There are two main sub-Saharan habitats; aquatic and terrestrial. Eggs are laid and develop in aquatic habitats; small pools of open shallow fresh or non-polluted water, irrigation areas, or in ephemeral bodies of standing water such as hoof prints, tyre tracks, exposed to sunlight. Adults are found in terrestrial habitats, close to and/or inside human habitations. The larval stages tolerate high levels of salinity and organic pollution in breeding habitats.

Compared to other species in the Anopheles gambiae species complex, An. coluzzii prevails in larger, more permanent aquatic habitats associated with irrigation, and is more tolerant of aridity or dessication stress and is found closer to sea levels. The species is also predominant in urban environments.

Found throughout tropical sub-Saharan Africa.

Additional Information
While hybrid males from most crosses between species of the An. gambiae complex are sterile, males from crosses between An. gambiae and An. coluzzii do not show signatures of genetic incompatibilities and are fully fertile, with no obvious loss in fitness under laboratory conditions.

Anopheles gambiae sensu lato is a complex of biological siblings which are genetically and behaviourally distinct and vary in their importance as malaria vectors. The members of the complex are morphologically indistinguishable as adults and are identified using molecular methodologies. The Anopheles gambiae complex of sibling species (1974; Coetzee et al., 2013) comprises nine related but reproductively isolated species that are almost indistinguishable morphologically: Anopheles amharicus (Hunt et al., 2013), Anopheles arabiensis (Patton 1905), Anopheles bwambae (White 1985), Anopheles gambiae (Giles 1902), Anopheles coluzzii (Coetzee & Wikerson 2013), Anopheles melas (Theobald 1903), Anopheles merus (Dönitz 1902), and Anopheles fontenillei (Barron et al., 2018).
