Flea facts
- They are wingless, with mouthparts adapted for piercing skin and sucking blood, and hind legs adapted for jumping
- They can jump a distance some 50 times their body length, a feat second only to the froghoppers
- Fleas are external parasites, living by hematophagy off the blood of mammals and birds
- Over 2,500 species have been described worldwide
- The Siphonaptera are most closely related to the snow scorpionflies (Boreidae), placing them within the endopterygote insect order Mecoptera
- Fleas arose in the early Cretaceous, most likely as ectoparasites of mammals and marsupials, before moving on to other groups including birds
- Each species of flea is more or less a specialist on its host animal species: many species never breed on any other host, though some are less choosy
- Some families of fleas are exclusive to a single host group: for example, the Malacopsyllidae are found only on armadillos, the Ischnopsyllidae only on bats, and the Chimaeropsyllidae only on elephant shrews
- The cat flea breeds on cats and dogs, and is the vector for Yersinia pestis, the bacterium which causes bubonic plague
- Fleas appear in human culture in such diverse forms as flea circuses, poems like John Donne's erotic The Flea, works of music such as by Modest Mussorgsky, and a film by Charlie Chaplin
