Anopheles quadrimaculatus, also known as the common malaria mosquito, is a species of mosquito mainly found in the eastern United States. The species is a main vector of malaria.
The common malaria mosquito is common across the southeastern United States, especially along the coast of the Gulf of Mexico.
Mosquitoes lay their eggs on still bodies of freshwater, where they float on the surface. Larvae take 2 to 3 days to hatch; these larvae lack breathing siphons, and so they rest parallel to the surface to breathe. The larvae take between 5 days and 2 weeks to mature depending on the environmental conditions. Adult mosquitoes typically live for approximately 2 weeks.
