Proboscis. Coloured scanning electron micrograph (SEM) of the tip of the proboscis of a female mosquito, Anopheles gambiae, carrier of the malaria parasite, Plasmodium sp. The proboscis is the feeding apparatus of the mosquito, consisting of a number of stylets (red) for piercing the skin and sucking blood. This array of instruments is enclosed by the labium (yellow), a protective sheath that folds around them but does not quite meet. The labium does not penetrate the skin, but bends backward to allow the stylets to slide through its tip into the skin in search of a blood vessel. Magnification: x505 at 6x7cm size.
