Eastern Fence Lizard (Sceloporus undulatus)

The subspecies of fence lizard found in our area is also known as the Northern Fence Lizard
(
Sceloporus undulatus hyacinthinus). This lizard is often seen basking in the sun on tree trunks or
fallen logs, where the lizard's brown and black markings provide a camouflage to protect it from
hungry birds. Fence lizards are fast moving and when they are approached they often dart up a
tree trunk to escape out of reach. They grow up to about six inches in length. They are
insectivorous, eating small insects.
