Eastern fence lizards vary in color geographically, but are usually gray, brown or a rusty color. Males and females are similar in size. Individuals in northern populations (northern New York south to Maryland) are generally smaller than individuals in southern populations (northern Virginia south to northern Florida). This may be because southern populations have a longer warm season in which to eat and grow.
Males have a blue patch on the belly and throat. Average adult mass is 15 g, while adult total lengths range from 9 to 19 cm.
Average mass: 15 g.
Range length: 9 to 19 cm.
Other Physical Features: ectothermic ; heterothermic ; bilateral symmetry
Sexual Dimorphism: sexes colored or patterned differently; male more colorful
