About Anopheles quadrimaculatus Say, 1824
Anopheles quadrimaculatus, commonly called the common malaria mosquito, is a mosquito species found mainly in the eastern United States. It is a primary vector of malaria. This mosquito species is common across the southeastern United States, and is particularly prevalent along the Gulf of Mexico coast. Females lay their eggs on the surface of still freshwater, where the eggs float. Larvae hatch from eggs 2 to 3 days after laying. These larvae do not have breathing siphons, so they rest parallel to the water's surface to breathe. Depending on environmental conditions, the larvae take between 5 days and 2 weeks to reach full maturity. Adult common malaria mosquitoes typically live for around 2 weeks.
