Fleas are wingless insects, 1,5- to 3.3mm (1⁄16 to 1⁄8 inch) long. Usually, their colour is dark reddish-brown and their body is shiny and covered with tiny hair that allows them to move easily through animal fur. Fleas live by consuming blood from their hosts. Their mouthpart is adapted for piercing the skin and sucking blood and hind legs that are adapted for jumping. A flea could jump up to 7inches -vertically and up to 13 inches - horizontally.
Fleas life stages: egg, larva, pupa and adult.
