EENY-434: Yellow fever mosquito Aedes aegypti (Linnaeus) (Insecta: Diptera: Culicidae)

Figure 6. An adult female yellow fever mosquito, Aedes aegypti (Linnaeus), in the process of acquiring a blood meal from its human host, after having penetrated the skin surface with the sharply-pointed "fascicle." Note that her abdomen has become distended as her stomach is filling with her blood meal, and how the proboscis' labial sheath is in its retracted, pulled back configuration, exposing the inserted, sharp fascicle, which has turned red, as the blood is passing up the straw-like apparatus.
