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

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.

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.
