Identification
This large-headed, small-scaled lizard has two black bands on its neck, or “collar”,
which are often broken at the nape of the neck. The collar pattern is constant
in this species, while the body color and pattern are variable. Male Eastern
Collared Lizards vary in coloration from yellowish, greenish, brownish or bluish,
and are patterned with light spots and dark bands that tend to fade with age.
They also have a yellow or orangish throat. Females have similar patterns, but
in contrast to males, are less brilliantly colored.
Distribution and Status
The Eastern Collard Lizard can be found through eastern and central Missouri,
on through central Texas, north to eastern New Mexico and southeast Colorado (US
distribution map; Midwest
distribution map).
The only Midwestern state that is home to this species is Missouri, where it
is widespread and abundant, but of long-term concern.
Ecology
Preferring rocky, semiarid conditions, the Eastern Collared Lizard can be found
in hilly regions with limestone edges or rock piles that support an abundance
of places to hide. When frightened, these lizards can run very quickly, and
often will run on their hind legs after gaining some speed. The Eastern Collared
Lizard enjoys dining on many kinds of insects and will also eat other lizards.
