Mating ticks Featured 29 Jun 2000 Print

Mating ticks

Mating ticks. Coloured scanning electron micrograph (SEM) of mating Ixodes sp. ticks. The male (green) is much smaller than the female (orange). This is known as sexual dimorphism. During copulation, a male tick approaches the female as she is feeding on her host. He inserts his proboscis into the female's sexual opening to widen it. He then deposits his spermatophore (bag of sperm) into the opening, and pushes it in with his head and legs. Only female ticks feed, and their only food is blood. They may feed on mammals, birds and reptiles. Ixodes sp. ticks are known to transmit Lyme disease to humans. Magnification unknown
