Rocky Mountain wood ticks

Where Rocky Mountain wood ticks live
Centers for Disease Control and Prevention (PD)

Spring has hit western Montana in full force. Days are longer than nights, temperatures are warming, and the snow is gone for the lower elevations. Animals that live here throughout the year, but become quiescent during the long, cold winters, are once again warm, active, and searching for their first meals of the spring. Such an animal is the Rocky Mountain wood tick, one of approximately 825 species of ticks known in the world, which as a group feeds solely on the blood of terrestrial vertebrates.
