Flea



Flea, wingless insect (order Siphonaptera) with legs developed for jumping and a laterally compressed body. It sucks the blood of host animals, and can carry such diseases as typhus and the bubonic plague. The flea survives its early stages in unsanitary conditions; when newly emerged, adults leap onto passing hosts.
