Overview: This exotic species was introduced into Cincinnati in 1951 and has since become well established. Sometimes referred to locally as âLazarus lizards,â the common wall lizards were brought to eastern Cincinnati from northern Italy by a local resident after a vacation near Milan and were released in a backyard.all lizards have a somewhat flattened body with long limbs and toes, an angular head, and a prominent jaw. Their backs are green or brown with black blotches. The belly is lighter in color.
The Sceloporus occidentalis, or northwestern fence lizard, is found in all regions of Northern California. A fairly small reptile, fence lizards are usually only 3.5 inches long from nose to vent (the underlying flap at the base of the tail).They are brown, gray or black, with tan flecks and the males have a divided, blue underbelly.Science has recently taken an interest in fence lizards, because their blood contains a protein that kills the bacterium that causes Lyme disease. Another common lizard of Northern California is the sagebrush lizard.ecause California spans most the West Coast of the United States and is 163,707 square miles or territory, the lizards within the state occupy a vast geographical terrain.
