Eastern Fence Lizard

Description

The Eastern Fence Lizard occurs statewide and is the only spiny lizard in Tennessee. A medium-sized (4.0 to 7.25 inches in length), wide-bodied grayish to brown lizard with keeled, pointed scales.  Females are larger than males and have dark, wavy lines across the back, while males are more uniformly colored.  Adult males have bright blue patches, bordered with black, along the throat and belly.

Similar Species: None.

Habitat: Found in many habitats, but usually found in dry, open forests or forest edges.  Commonly found on trees, fallen trees, stumps, fences, firewood piles, and rock piles.

Diet: Primarily insects such as ants, beetles, and spiders; occasionally snails.

Breeding information: Adults court and breed in spring and summer.  Males attract mates by flashing their blue patches.  Males defend territories aggressively with head-bobbing and push-ups, occasionally with fighting. Females lay 3-16 eggs in rotting wood piles or under loose soil.  Juveniles hatch in late summer, appearing as small adults.

Status in Tennessee: Common across Tennessee. This species is relatively tolerant of habitat disturbance.

Best places to see in Tennessee: Any dry, woodland habitat across the state, especially fallen wood piles.
