“What kinds of skinks are there in Pennsylvania?”

Coal Skinks are one of the most secretive, shy skinks in Pennsylvania!
They are hard to find because they spend so much of their time under rocks, leaf litter, or fallen logs. Coal Skinks prefer moist, humid areas and live on hillsides with nearby streams.
If you spot a Coal Skink, you can identify it by the lack of a middle stripe on its back.
Two subspecies, the Northern Coal Skink (P.a. anthracinus) and the Southern Coal Skink (P.a. pluvialis), are scattered throughout the US.
#2. Common Five-Lined Skink
- Plestiodon fasciatus
- Adults are up to 8.75 inches long.
- 5 stripes are most apparent in hatchlings and fade as the skinks grow.
- Males have orange-red coloring on the jaw during the breeding season.
- Hatchlings are black with light stripes. The black coloring often fades to gray, and the lighter stripes darken.
Look for Common Five-Lined Skinks in Pennsylvania in wooded areas near rotting stumps, outcrops of rock, and sometimes piles of boards or sawdust. Its diet consists of spiders, beetles, crickets, and other insects.
