Distribution

The Eastern fence lizard is widely seen in Georgia, California, Alabama, Virginia, Kentucky, Ohio, Pennsylvania, West Virginia, southern New Jersey and northern Florida. Isolated populations of these lizards do exist outside this range, however.

 Behavior

They have interesting behavioral characteristics:

  • The fence lizards are most active in the months of spring and in the fall
  • They are a diurnal species and are often seen dashing off a rock where they seem to have been basking.
  • They will lay motionless if you flip them over in your hand and run your finger along their belly.
  • They hibernate during winter

Diet

Eastern Fence lizards are carnivorous, and eat spiders and small insects such as grasshoppers.

Adaptations

  • Their skin color helps them to hide from their predators
  • Fence lizards can stay motionless for a long time.

Predators

Their main predator is the fire ant, and studies have shown that these ants are capable of devouring a lizard within minutes. Other predators include Broadhead skinks, several types of birds, snakes, and many other carnivores.

Hibernation

They hibernate in the winter season and emerge in spring.

Mating Season

Eastern fence lizards mate in early spring or at the beginning of summer.

Reproduction

After emerging in the spring, male lizards set up their mating territories. The moment other males and females move inside the boundary of their territory, the male lizard will display behaviors that include push-ups showing off their bright, blue colored extension of the dewlap.

The female lizard lays 3-10 eggs of elliptical shape in a nest in the soil. Yearlings are capable of laying 1 clutch per season. Older females lay anywhere from 2-4 clutches per breeding season. Eggs are hatched between June and September.

Life Cycle

The eggs hatch in 60-80 days. After one month juveniles start climbing up trees in search of food.

Lifespan

Their lifespan varies depending on the region they inhabit. In the south they live more than 2 years (60% die before reaching 1 year of age). In the north, their lifespan can be to 4 to 8 years, due to their hibernation in colder weather.

Interesting facts

There is much more to know about these interesting reptiles:

  • Fence lizards love basking in the sun
  • They bear a close resemblance to the western fence lizard.
  • A recent study stipulated that these lizards have developed longer legs in order to be able to run away from the invasive fire ant.
