The lined snake is a secretive snake that can be found hiding underneath rocks, logs and man-made debris, or buried within loose soil during the day (5) (6). It is active during the night, and is sometimes referred to as a nocturnal species, although it is known to bask in the morning sun (3) (6). It is particularly likely to be actively hunting during and after heavy rainfall when there is an increased likelihood of catching earthworms (2) (3) (6). Although the lined snake is thought to feed mostly on earthworms (5), it has been known to eat woodlice (3).
The lined snake mates during late summer or autumn (2) (3). The female then stores the sperm within the oviducts during hibernation over winter, and fertilises her eggs the following spring (3) (6). Gestation takes around 70 days, and the young are born in August or September (2) (6). An average litter will contain between 4 and 10 young snakes that are about 7 to 12 centimetres in length (2) (3) (6). They are born alive and surrounded in a thin, transparent membrane (3). The lined snake grows quickly, and both sexes reach sexual maturity after two years, although males have been known to mate from as young as eight months old (6).
When threatened, the lined snake will tightly coil its tail (2) and hide its head underneath the coil, or flatten its body (6). If it is captured, it can release an anal discharge while it is trying to escape, but it is otherwise passive and not known to bite (6).
