Anopheles albimanus occurs mainly in tropical and subtropical lowland environments and is considered an ecologically adaptable generalist species. Immature stages develop in a wide range of natural and artificial aquatic habitats, particularly open, sunlit water bodies, including ponds, marshes, lagoons, rice fields, irrigation and drainage channels, stream and river margins, and temporary pools. Larvae occur in both freshwater and brackish-water habitats, including coastal areas and mangroves. Adults occupy terrestrial habitats in rural, agricultural and peri-domestic environments and exhibit opportunistic feeding behaviour and substantial dispersal capacity. Females have been reported to disperse up to approximately 32 km, and the species has been recorded at elevations approaching 2,000 m above sea level.
