Ixodes pacificus

A species of Ixodes, Also known as California black-eyed tick, California black-legged tick

Within the temperate forests and grasslands, western Blacklegged Tick have adapted to a life that crucially depends on blood meals, sourced from a variety of hosts during their various growth stages. These ectoparasites embody a fascinating exemplar of disease vectors, carrying pathogens like the bacteria responsible for Lyme disease. They exhibit a remarkable change from immature stages, preferring lizards as their primary hosts, to adults primarily seeking larger warm-blooded animals. Their ability to navigate diverse habitats and host environments underscores their resilience and ecological adaptability.

Asian longhorned tick
Asian longhorned tick

Haemaphysalis longicornis, the Asian longhorned tick, longhorned tick, bush tick, Asian tick, or cattle tick, is a parasitic arachnid belonging to the tick family Ixodidae. The Asian longhorned tick is a known livestock pest, especially in New Zealand, and can transmit a disease called theileriosis to cattle but not to humans. However, the tick has been associated with several other tickborne diseases in humans. An unfed female is typically 2.0–2.6 mm long and 1.5–1.8 mm wide, and grows to 9.8 mm long and 8.2 mm wide with engorgement. Distinguishing a specimen from other members of the genus Haemaphysalis requires microscopic examination of minor physical characteristics.

Gulf coast tick
Gulf coast tick

Ticks are temporary ectoparasites on the surfaces of the bodies of vertebrates and are also mediums for zoonoses. When they bite animals, they would also inject saliva with anesthetic effects, misleading the host to dismiss the harm they are creating. As the time span of the bite increases, the probability of contracting diseases increases as well.

Cayenne tick
Cayenne tick

The skin of cayenne tick is a unique natural marvel, capable of expanding several times its initial size to accommodate a blood meal from its host. As both nimble nymphs and diligent adults, they depend on a variety of mammals for sustenance, but display a marked preference for horses during their adult phase. This dietary specificity is essential for completing their complex life cycle.

Ticks are temporary parasites on the surface of the body of many vertebrates. They are also mediums for spreading some of the zoonoses. When they are biting animals, they would inject saliva with anesthetic effects, misleading the host to dismiss the harm they create.

Ornate sheep tick
Ornate sheep tick

Often found clinging to the tips of grasses and shrubs, ornate sheep tick exhibits a unique questing behavior, where it patiently awaits the approach of a host. Sporting a distinctive pattern on its back, it surreptitiously latches onto the unsuspecting host to feed. As an ectoparasite, it has evolved a complex saliva that not only facilitates blood-feeding but also can transmit various pathogens, a subject of significant study due to its role in the ecosystem and impact on wildlife health.
