The young of Plethodon cinereus in Maryland are first abroad during September, approximately two to three weeks after hatching. The rate of growth is more rapid during the first active growing season than during the second growing season. Immature specimens attain maturity at the end of the second year of growth. Samples of 539 specimens collected at Cunningham Falls State Park during May 1956 to 1963 revealed that three size groups are present: two groups of immatures and one group of mature specimens. No sexual dimorphism in snout-vent lengths is present in the mature individuals.
