Role in the Web of Life
These nocturnal predators consume a variety of small invertebrates and are also known to be cannibalistic. Mating probably occurs in spring with females laying 9–20 eggs in cavities near water in late spring to summer. Females remain with the nest until eggs hatch in the fall. Metamorphosis occurs the following spring.
Species appears to be secure in Virginia.
