Common Gartersnakes Mating
Common Gartersnakes begin mating in the spring as soon as they emerge from brumation (a reptilian state of dormancy similar to hibernation in mammals, but involving different metabolic processes). The males leave the den first and wait for the females to exit. Once the females leave the den the males surround them, forming what is called a mating ball (one female and many males). The males give off pheromones that attract the female. After the female has chosen her mate and mated, she leaves. while the males stay to re-mate with other available females. The females have the ability to store the male’s sperm until it is needed and thus a female may not mate if she does not find a proper partner.
