This figure displays the life cycle of Wuchereria bancrofti in humans and mosquito vectors (ie, Aedes, Anopheles, Culex, Mansonia species). Life cycles of other lymphatic nematodes (ie, Brugia malayi, Brugia timori) are identical, while the life cycles for other filariae differ in the body location of adult worms, the microfilariae present, and the arthropod intermediate hosts and vectors.
