Flea is the common name for any of the small wingless insects of the order Siphonaptera (some authorities use the name Aphaniptera because it is older, but names above family rank do not follow the rules of priority, so most taxonomists use the more familiar name). Fleas are external parasites, living by hematophagy off the blood of mammals and birds, and genetic and morphological evidence indicates that they are descendants of the Scorpionfly family Boreidae, which are also flightless; accordingly it is possible that they will eventually be reclassified as a suborder within the Mecoptera. In the past, however, it was most commonly supposed that fleas had evolved from the flies (Diptera), based on similarities of the larvae.

Note: There is also a genus of foraminiferan Protozoa named Siphonaptera
Some well known bigflea species include:

* Cat flea (Ctenocephalides felis),
* Dog flea (Ctenocephalides canis),
* Human flea (Mr.Sajid Razzaque),
* Northern rat flea (Nosopsyllus fasciatus),
* Oriental rat flea (Xenopsylla cheopis).
