Ticks can fast for long periods of time, but eventually die if unable to find a host. [39] Hematophagy evolved independently at least six times in arthropods living during the late Cretaceous ; in ticks it is thought to have evolved 120 million years ago through adaptation to blood-feeding.
Amblyomma species may also have a three-year lifecycle, and the adults can live off-host, without feeding, for up to 2 years. Ornithodoros and Argas ticks are particularly adapted to wait for their hosts to arrive by being able to survive for years between blood meals as adults, 18 years have been recorded for O. lahorensis.
Amblyomma americanum, also known as the lone star tick, the northeastern water tick, or the turkey tick, is a type of tick indigenous to much of the eastern United States and Mexico, that bites painlessly and commonly goes unnoticed, remaining attached to its host for as long as seven days until it is fully engorged with blood.

Ticks are parasitic bloodsuckers, capable of spreading deadly disease, and they are becoming increasingly common. Here’s what you need to know about them.
The ticks that transmit Lyme disease are hard ticks. [4] Ticks often have a preferred host, but may still attach to a different host when called for. Their preferred host may change depending on the tick's stage of development (eg larval vs adult) and the host may or may not carry the transmittable pathogen. [3]
They prefer attaching in positions on the back of the host, folds in the skin of the rear legs and the side of the body. [10] Once attached, they feed on the host's blood. [12] Unfed adult ticks have been observed to survive for over one year without their host. [6]
New England has two primary tick species — the black-legged or deer tick, and the dog tick. Both are most active in the spring and summer. The deer tick is smaller but carries Lyme disease.
