Mating ticks. Close-up of mating ticks,Ixodes ricinus,on the skin of a dog. The female tick appears grey and is greatly distended because of blood she has sucked from the dog's skin. The much smaller male (dark brown) is obscuring her head. Only adult female Ixodes ticks are parasites,the males do not feed in their adult stage. The females have specially adapted mouthparts which allow them to attach firmly to the host's skin and bore through to reach the blood system. Ticks may attack practically all haired animals,including humans. This tick is the cause of Lyme disease in humans | |
