The Coluber constrictor foxii, commonly known as the Blue Racer, is native to North America. It is primarily found in the Great Lakes region, with its range extending from southern Ontario, Canada, through Michigan, Ohio, Indiana, Illinois, and into parts of Wisconsin and Iowa in the United States.

The Blue Racer typically inhabits open or semi-open areas, such as grasslands, savannas, and open woodlands. It prefers environments with a mix of vegetation and open ground, which provide opportunities for hunting and basking. The climate in these regions is generally temperate, with cold winters and warm summers.

The Blue Racer occupies the ecological niche of a terrestrial predator, primarily feeding on small mammals, birds, and insects. It is an active hunter, often seen during the day, and relies on its speed and agility to capture prey. The species plays a role in controlling populations of its prey and maintaining ecological balance in its habitat.
