This exotic species was introduced into Cincinnati in 1951 and has become well established. Sometimes referred to locally as “Lazarus lizards,” 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. The lizards can now be found in several areas in Hamilton County and have established themselves in neighboring Kentucky and Indiana, with population densities of 1,500 per acre in good habitat.
The lizards are primarily found along old rock walls, railroad tracks, refuse piles, or occasionally in rocky ravines. Because they have persisted for many years and survived through record-setting severe winters, they are considered permanent residents. It is unknown what effects the common wall lizard will have on native species, but their spread should be discouraged. It is illegal to release this or other animals into the wild in Ohio. |

Description
Wall 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.
Habitat and Habits
Two lizards reportedly were brought to the Cincinnati area from northern Italy by a local resident after a vacation near Milan and were released in a backyard. The lizards now occupy an area slightly larger than two square miles, with population densities of 1,500 per acre in good habitat. Because they have persisted for many years and survived through record-setting severe winters, they are considered permanent residents.
Reproduction and Care of the Young
Mating occurs shortly after hibernation in the spring and the eggs are laid about one month later. Females either bury the eggs or deposit them under a rock. They hatch one month later. No parental care is involved. |
