These L3 migrate to the mosquito head and mouthparts where they are deposited in hemolymph onto mammalian skin during subsequent blood meals. After the deposited L3 enter the host through the mosquito bite wound, they molt to fourth-stage larvae (L4). The L4 then migrate through the tissues toward...
