Ticks -

are specialized, blood-feeding arachnids more closely related to spiders and mites than to insects. These obligate ectoparasites require a blood meal at every stage of their life cycle to survive and develop. While small, they are among the most significant vectors of disease globally, transmitting a wider variety of pathogens—including bacteria, viruses, and parasites—than any other group of arthropods. Biology and Life Cycle

Ticks undergo a complex four-stage life cycle: . Biology and Life Cycle Ticks undergo a complex

Some species, like the blacklegged tick, can live for two to three years, though they may only take three blood meals during their entire lifetime. Ticks cannot jump or fly

To transition between stages, a tick must find and feed on a host. Ticks cannot jump or fly. Instead

Ticks cannot jump or fly. Instead, they perform "questing"—climbing to the tips of grasses or shrubs and waiting with outstretched legs to latch onto a passing host. Habitat and Emerging Threats
