Fall and spring activity peaks are associated with movement to and from the hibernacula as well as mating and feeding. Racers are beneficial to humans in that they destroy rodent and insect pests.

Distribution:

Racers occur from southern Canada to Guatemala, with considerable individual and local variation in regions where two or more subspecies intergrade.
