About Flea

The 2,500 species of small, flightless insects that make up the order Siphonaptera commonly known by the term “flea” live as external parasites of mammals and birds.

The blood of their victims is what fleas consume to survive.

Fleas may pass through their hosts’ fur or feathers thanks to their “flattened” sideways or narrow bodies, which are about 3 millimeters (1/8 inch) in length, often brown, and in size.


More Things to Know

Their rear legs are incredibly well suited for jumping, but they lack wings. Their mouthparts are designed for piercing skin and sucking blood, while their claws prevent them from being moved.

They can leap 50 times their body length, which is a feat only surpassed by the superfamily of froghopper insects. Flea larvae resemble worms and have no legs.

They consume organic matter that has been left on their hosts’ skin with their chewing mouthparts.
