A female yellow fever mosquito Aedes aegypti feeding on human blood. Visible beneath the head is the proboscis, which is inserted into the skin. The proboscis consists of a labium, or sheath, that surrounds the slender sucking & piercing stylets. During feeding the labium is drawn back elbowlike (seen here under the head), allowing the stylets to plunge into the skin & drink (blood is seen in the tubes). Only the female drinks blood. It is a necessity for the proper development of her eggs. During her blood meal the female may transmit the arbovirus responsible for yellow fever. The male feeds on nectar.
