CHIGOE (Tunga penetrans): SPECIES ACCOUNTS
SHEEP AND GOAT FLEA (Dorcadia ioffi): SPECIES ACCOUNTS

Fleas are found on all continents, including Antarctica. There are 2,575 species of fleas worldwide, 258 of which occur in North America.

There are no fleas that are considered endangered or threatened. However, flea species that feed only on one host species are vulnerable to extinction if their hosts were to become threatened by extinction. In these cases the fleas would share the fate of their hosts. No one has yet attempted to identify or list fleas that feed only on species listed by the World Conservation Union (IUCN).

Fleas: Siphonaptera - Behavior And Reproduction

The survival of every flea species depends on its ability to find a suitable host. Some species remain in the pupal stage for long periods of time to survive cold weather or to wait until a host comes by. The vibrations of an approaching host often trigger adults to emerge from their pupae (PYU-pee). Although fleas cannot see very well, they do respond to moving shadows by jumping. They are also a…
