Close-up of an unidentified species of mosquito on human skin. The mosquito's proboscis (thin reddish-brown structure) is visible poised just above the skin at right, ready to bite. The elbow- shaped mouthpart which is seen gripping the proboscis about half way down is the stylet sheath, a modified labium. This sheath normally covers the proboscis, but bends backwards as the mosquito bites, allowing the proboscis to slide through its tip and penetrate the host's skin.
