Walls lizards (Podarcis muralis), also known as common wall lizards or European wall lizards, are a fascinating reptile species found across Europe and parts of Asia. These small but mighty creatures are a common sight in urban environments, basking on walls, fences, and rooftops. They’ve adapted remarkably well to human presence, turning our concrete jungles into their own personal playgrounds!
Walls lizards belong to the Lacertidae family, which includes over 300 species of lizards. These are typically diurnal reptiles, meaning they’re most active during the day. Their slender bodies, ranging from 15 to 25 centimeters in length, are covered in overlapping scales that provide camouflage and protection against predators.
A Master of Disguise: Physical Characteristics
Walls lizards possess a distinctive coloration that helps them blend seamlessly into their surroundings. Their dorsal (back) side is typically brown or grey, with darker markings and stripes that resemble the textures of stone walls and bark. They have a lighter ventral (belly) side, often yellowish or white.
These lizards are renowned for their incredible agility and climbing abilities. Their sharp claws and sticky toe pads allow them to scale vertical surfaces with ease. Their long tails, which can regenerate if lost, also play a crucial role in maintaining balance while navigating complex terrain.

Urban Survivors: Habitat and Lifestyle
Walls lizards are highly adaptable creatures that thrive in a variety of habitats, including urban areas, woodlands, grasslands, and rocky outcrops. Their tolerance for human disturbance allows them to coexist alongside us in our cities and towns.
They’re often observed basking on walls and fences, absorbing the warmth of the sun to regulate their body temperature. These lizards are insectivores, feeding primarily on insects such as ants, spiders, flies, and moths. They use their quick reflexes and sharp teeth to capture their prey.
While walls lizards generally prefer solitary lives, they can sometimes be observed congregating in groups, especially during mating season. Males engage in territorial displays, bobbing their heads and extending their dewlaps (throat pouches) to attract females and ward off rivals.
Interesting Fact: Walls lizards are known to shed their skin several times a year. This process allows them to grow and remove parasites. The discarded skin is often found near basking sites or under rocks.
The Walls Lizard: A Vital Part of the Ecosystem
Though they may appear small and inconspicuous, walls lizards play an important role in maintaining healthy ecosystems. As insectivores, they help control populations of insects that can be harmful to crops and gardens. Their presence also indicates a thriving environment with sufficient food sources and suitable shelter.
Conservation efforts for walls lizards are generally focused on preserving their habitat. This includes protecting natural areas from development and reducing the use of pesticides that can harm lizard populations.
By understanding and appreciating these remarkable creatures, we can contribute to their conservation and ensure they continue to thrive in our world.
