Anopheles quadrimaculatus
common malaria mosquito
Anopheles quadrimaculatus is a mosquito species historically recognized as the most important malaria vector in the eastern United States. It belongs to a sibling species complex that includes at least four genetically distinct forms. The species breeds in freshwater habitats, particularly intermittently flooded swamps and rice fields. While it remains capable of transmitting Plasmodium parasites, local malaria transmission in its range has been eliminated through vector control and public health measures.
Culex
typical mosquitoes
Culex is a diverse genus of mosquitoes comprising over 1,000 species across more than 20 subgenera. Several species serve as important disease vectors, transmitting arboviruses including West Nile virus, Japanese encephalitis, and St. Louis encephalitis, as well as filariasis and avian malaria. The genus occurs worldwide except for extreme northern temperate regions and is the most commonly encountered mosquito in many major U.S. cities. While most Culex species exhibit characteristic raft-forming egg-laying behavior, at least one species, Culex antillummagnorum, has been documented with unique aerial and "barrage" oviposition strategies.
