Rocky Mountain Wood Tick
Appropriately named, the Rocky Mountain Wood tick (Dermacentor andersoni) is found predominantly in states with the Rocky Mountains, and is typically found in shrubs, lightly wooded areas, and grasslands. As with its very close cousin, the American Dog tick (Dermacentor variabilis), Rocky Mountain Wood ticks are a known vector of Rocky Mountain Spotted Fever, Tularemia, and Anaplasmosis; as well as Colorado Tick Fever and Tick Paralysis in both humans and pets.
Adult ticks feed primarily on large mammals, while larvae and nymphs feed on small rodents. Adult stage ticks are the ones primarily associated with pathogen transmission to humans. Wood ticks typically take two to three years to complete their life cycle.
