The middle stripe tends to be narrower than the others, and the dark areas between stripes are black in young skinks but become brown with age. A similar

, the common five-lined skink (''

''), is slightly smaller than the southeastern five-lined skink and has broader stripes. However, it is difficult to discriminate between these two species on the basis of physical appearance. Young southeastern five-lined skinks have a bright blue or purplish tail, especially towards the tip. Also, stripes become a bright reddish orange towards the head. Juvenile coloration may persist into adulthood, giving the head of the animal an altogether orange-brown appearance.

Habitat

Southeastern five-lined skinks are common inhabitants of wooded areas of the southeastern United States. They are commonly found on small islands off the southeastern coast even in the absence of fresh water and vegetation.

Behavior

They are diurnal ground-dwelling animals.

Diet

Like other skinks of the genus ''Plestiodon'', they feed primarily on insects, preferring larger prey such as

; the clutch size varies from 6 to 12, with the number of eggs diminishing with higher latitudes. The female broods the eggs and protects them from predators, including other skinks. The hatchlings appear about one month after the eggs have been laid near the beginning of summer.
