Caption: Cat flea egg and faeces. Scanning electron micrograph of faeces and an egg of the cat flea, Ctenocephalides felis. Cat fleas are small, blood- sucking, wingless insects. They spend only a fraction of their lives on the host, spending most of their time lying in wait where the cat sleeps. Eggs may be laid on the ground or on the host, from which they soon drop off. The maggot-like larvae hatch after several days and feed on organic debris, favouring the faeces of adult fleas, which are rich in undigested blood. After moulting twice the larvae spin woolly cocoons and metamorphose into adults. Magnification unknown.
