Bush Tick (Haemaphysalis longicornis)

The scrub or bush tick, Haemaphysalis longicornis, is a parasitic tick commonly found on domestic animals in Australia and New Zealand. Also known as the New Zealand cattle tick, this ectoparasite of dogs, cattle, donkeys, and horses, was first introduced "Down Under" from northern Japan around 1900, but is now found throughout the Western Pacific Rim and some of the Pacific Islands including Hawaii and Fiji. These ticks are also known to infest deer, sheep, goats, pigs, and humans, as they spread throughout the region.
