How many types of mosquito are there?
There are over 3,500 species of mosquito! However, most of these do not transmit any diseases to humans. Mosquitoes are usually divided into two sub-families, the Anophelinae and the Culicinae. The latter group consists of about 40 genera, including Culex and Aedes, which contain some species that transmit diseases to humans (such as yellow fever, dengue fever and West Nile). The former contains the genus Anopheles, which are the mosquitoes that transmit malaria. There are about 460 described species of Anopheles mosquito, of which about 100 can transmit malaria, though the vast bulk of transmission is usually limited to about 30 species.
