Eastern Fence Lizard

Eastern Fence Lizards in Pennsylvania exhibit a wide range of colors, from gray to brown, with a distinctive whitish to greenish blue belly. These spiny lizards are easily recognizable by the keeled and rough scales on their backs.

Females display dark, wavy crossbars on their back, while males boast a unique blue throat patch. Typically found in open forests in southern Pennsylvania, Eastern Fence Lizards are skilled climbers and are often seen basking on tree trunks or fence posts.

During the breeding season, males may develop reddish blotches on their heads as a part of their courtship display. Their coloration and markings serve as effective camouflage in their woodland habitat, aiding in both thermoregulation and predator avoidance.

This skink species, scientifically known as Plestiodon anthracinus, exhibits unique characteristics that set it apart from other local skinks:

  • Lack of light lines on the head makes it easily distinguishable.
  • Breeding males may display a reddish head, adding to their distinct appearance.
  • Young Northern Coal Skinks can have a striking blue tail, a feature particularly noticeable in juveniles.
  • Preferring moist habitats on hillsides near streams, this skink demonstrates a specific ecological niche.
  • Contributing significantly to Pennsylvania’s reptilian diversity, the Northern Coal Skink is a notable lizard species in the state.

Common Five-Lined Skink

Plestiodon fasciatus, the Common Five-Lined Skink in Pennsylvania, exhibits distinctive features that make it a notable lizard species in the region. These skink species can grow up to 8.75 inches long, with juveniles displaying five distinct stripes that gradually fade as they mature.

During the breeding season, male Common Five-Lined Skinks showcase vibrant orange-red coloring on their jaws. Their diet primarily consists of insects such as spiders, beetles, and crickets. You can commonly find Common Five-Lined Skinks in wooded areas near stumps and rock outcrops throughout Pennsylvania.

Keep an eye out for these fascinating creatures as they navigate their natural habitats with agility and grace.

Mediterranean House Gecko

Transitioning from the impressive Broad-Headed Skink, the Mediterranean House Gecko, a relatively small lizard measuring between 1.5 to 2.5 inches in length, introduces a new fascinating species to observe in Pennsylvania. This gecko, not native to the region, was introduced through imported plants and is commonly found in urban areas. The Mediterranean House Gecko displays two color phases for camouflage, aiding in blending into its surroundings effectively. Nocturnal by nature, it primarily emerges during the night to feed on insects. Interestingly, this gecko emits clicking and squeaking noises as part of its behavior, adding to its mystique.
