Ticks mating with bodies flat together. The ticks are on the skin of a mammal, feeding on the blood of their host. The female tick swells while ingesting a blood meal. The female tick then lays hundreds to thousands of eggs. The life stages of a tick are: egg, larva, nymph and adult. Ticks (superfamily: Ixodoidea) are small arachnids. They are ectoparasites, feeding on the blood of mammals (including humans), birds, and occasionally reptiles and amphibians. Ticks transmit several diseases, including Lyme disease, Colorado tick fever, and relapsing fever. | |
