Green Salamander
Aneides aenus

Green salamanders are a small to medium sized salamander found in southwestern Pennsylvania. Elsewhere they occur along the Appalachian Mountains to northern Alabama. In Pennsylvania, they are only found on sandstone outcrops of the Pottsville Formation. Individuals can be found in moist crevices on the face of these outcrops.

The yellowish-green lichen pattern and square toe-tips distinguish this species from all other salamanders in Pennsylvania. All other members of the genus Aneides occur on the west coast of the United States. This species feeds almost entirely on insects. Activity is not strongly correlated with time of day. Courtship and egg deposition occurs during early June in similar rock crevices to those used for shelter. Between 10 and 26 eggs are laid and development is direct, with young emerging in September.

Green salamanders are listed as a threatened species by the Pennsylvania Fish & Boat Commission due to their restricted range and strict habitat requirements.
