Aedes aegypti: transmits yellow fever and dengue; identified by conspicuous white markings
Aedes albopictus: Asian tiger mosquito; native of Japan, thriving in southwestern and midwestern US and spreading to the Caribbean; potential carrier of serious diseases. Identified by black and white striped legs
Anopheline: About 400 species exist, of which 30-40 transmit four different species of parasites of the genus Plasmodium that causes malaria. Anopheles gambiae is one of the best known, because of its predominant role in the transmission of the most dangerous Plasmodium falciparum.
