When mosquito bites, maxillae penetrate the skin and anchor the mouthparts, thus allowing other parts to be inserted. The sheath-like labium slides back, and the remaining mouthparts pass through its tip and into the tissue. Then, through the hypopharynx, the mosquito injects saliva, which contains anticoagulants to stop the blood from clotting ...
A large part of the mosquito's sense of smell, or olfactory system, is devoted to sniffing out blood sources. Of 72 types of odor receptors on its antennae, at least 27 are tuned to detect chemicals found in perspiration. [36] In Aedes, the search for a host takes place in two phases.

Mouthparts of a female mosquito feeding on blood. The flexible labium supports the bundle of stylets which penetrates the host's skin. In female mosquitoes, all mouthparts are elongated. The labium encloses all other mouthparts, the stylets, like a sheath. The labrum forms the main feeding tube, through which blood is sucked.
Culex or typical mosquitoes are a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals. The diseases they vector include arbovirus infections such as West Nile virus , Japanese encephalitis , or St. Louis encephalitis , but also filariasis and avian malaria .
Culicinae mosquitoes are holometabolous, going through four distinct life stages: egg, larva, pupa, and adult. The duration of each stage is species-specific, but all Culicinae mosquitoes are multivoltine. The egg, larval, and pupal stages are aquatic. Adults leave the water by flight to find plants or vertebrates on which to feed.
The earliest insects had chewing mouthparts. Specialisation includes mouthparts modified for siphoning, piercing, sucking and sponging. These modifications have evolved a number of times. For example, mosquitoes and aphids both pierce and suck; however, female mosquitoes feed on animal blood whereas aphids feed on plant fluids. This section ...
