Proboscis is inserted into the skin.
Imbibing. Females can also excrete clear to reddish fluid while bloodfeeding in order to concentrate the protein as much as 2 fold (Figure). A complete withdrawal can occur or only a partial one with re-insertion.
. Without movement; Penetration. There is data that substantiates blood as also providing a source of energy since blood fed females have been shown to survive longer than females given only water. After a mosquito lands on its host. The mouthparts vary among the types of mosquitoes. It is very common for a mosquito to take as much as 2-4 times their weight of blood in a single meal; Exploration.
Phases of Blood-feeding
Probing.
Mouthparts Used in Feeding
Mosquitoes have mouth parts conducive to taking up liquids. Anopheles and Aedes remain stationary for a period of time after landing on a human. This process begins when the palps stop vibrating from the penetration process, the mosquito explores the skin either in the area of landing or sometimes moving around.This action takes about 3 seconds. Females have more complex mouthparts because they must probe flowers and pierce skin. Prior to penetration, it goes through an exploratory phase before penetrating the skin. Host movement during this time causes the mosquito to leave; WithdrawalBlood
Only females take blood meals. After final withdrawal. The blood is their resource for protein needed in ovary development.
