Ticks

Ticks are blood-feeding parasites that are often found in tall grass and shrubs where they will wait to attach to a passing host. Physical contact is the only method of transportation for ticks. Ticks do not jump or fly, although they may drop from their perch and fall onto a host. Some species actively stalk the host by foot. Young ticks have six legs, and mature ticks have eight legs. They are about the size of a sesame seed, and males are black; females have a brick-red abdomen with a black shield-like plate close to their head. Source: Wikipedia.com
