Caption: Cat flea sucking blood. Coloured scanning electron micrograph of a cat flea (Ctenocephalides felis) sucking blood from the skin of its host. The specialised, piercing stylet can be seen entering the skin. The cat flea is a small, blood-sucking, wingless insect. Its laterally compressed body and glossy cuticle enable it to move easily through dense fur, while the backward-pointing spines around its head prevent it from falling out. The flea's ability to jump is made possible by compressed pads of elastic "resilin" in the hind legs. When released, the pads spring the insect forward with great speed. Magnification unspecified.
