Caption

Cat flea. Coloured scanning electron micrograph of a cat flea sitting on a hypodermic needle. The cat flea (Ctenocephalides felis) is a small, wingless, blood-sucking insect. Its helmet-shaped head, flattened 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. Adults gorge themselves intermittently on blood and can survive for up to six months between meals. Magnification unspecified.
