Where do the larvae and nymphs of the Rocky Mountain wood tick primarily feed?

The larvae and nymphs of the Rocky Mountain wood tick primarily feed on small animals, especially ground squirrels. This is significant because these stages of the tick rely heavily on smaller hosts to obtain the blood they need to grow and develop. Ground squirrels are particularly important as they are prevalent in the habitats where these ticks are found, providing an easy source of nourishment.

The lifecycle of the Rocky Mountain wood tick includes various stages, each with specific host preferences. During their larval and nymph stages, these ticks are not equipped to feed on larger mammals, which may not be accessible to them due to their size. The choice of small mammals as hosts allows the ticks to effectively complete their developmental stages while adapting to their ecological niche.

Additionally, while adult ticks do often feed on larger mammals, the focus for larvae and nymphs is distinctly on smaller animals, primarily due to their size and feeding behavior. This understanding of the tick's life cycle and feeding habits is crucial for comprehending their role in the ecosystem and their potential impact on public health, as they can transmit diseases during their feeding process on these smaller animals.
