By far the most common lizard in France, the common wall lizard (Podarcis muralis) is a species of lizard with a large distribution in Europe and well-established introduced populations in North America, where it is also called the European wall lizard. Males are far more colourful and patterned than females, which are often a drab brown, and its small scales are highly variable in colour and pattern. The row of spots along their backs may form a line, while others may have a reticulated pattern with dark spots on the side and scattered white spots that can be blue in the shoulder region.
