摘要:

Males of two species of garter snake (Thamnophis) were tested monthly, April-October, for their ability to follow trails laid by conspecific females in a 183 by 122 cm arena. Thamnophis sirtalis trailed best in April, May, and June; did not trail in late July; and showed intermediate trailing ability in August, September, and October. This variation in trailing activity reflects seasonal changes in the reproductive activity of this species. Thamnophis proximus males trailed females equally well throughout the entire season. As this species' reproductive habits are less known, it still is possible that the pheromone trail is involved primarily in reproduction.
