False-colour scanning electron micrograph (SEM) of the pubic louse,Phthirus pubis,also known as the crab louse,clinging to a human pubic hair. An infestation of P. pubis causes pediculosis,the symptoms of which are severe itching and a rash. The lice suck blood,feeding 5 times a day. They spread through sexual contact and via bedding or clothing. Each of the louse's 6 legs terminates in a massive claw,which folds inward to meet a thumb-like projection on the opposite side. The louse climbs and swings through its hairy habitat,locking into position when disturbed,for instance by scratching or washing. Magnification: x45 at 6x7cm size,x20 at 35mm size. Rossdale colouring: yellow,green & blue louse with yellow/brown hair | |
