Tick Biology and Ecology

This section covers the fundamental biology of ticks, including their classification, body structures, and the species most commonly encountered in North America. Explore tick seasonality, geographic distribution, and the ecological factors that influence where and when ticks are active.

In this section

  • What Ticks Are — This section explores the biological classification of ticks and the two main types you're likely to encounter. Learn how ticks relate to other arachnids and how their different body structures and feeding habits distinguish hard ticks from soft ticks.

  • The Species That Matter — Learn about the tick species most commonly responsible for human disease in North America, including how to identify them, where they live, and what pathogens they transmit.

  • Seasonality and Range — This section explores when ticks are active throughout the year and how their geographic ranges are changing. Learn about seasonal patterns across major U.S. tick species and the factors reshaping where ticks are found.
