Podarcis liolepis (Boulenger, 1905)

Nomenclature and Taxonomic Placement

Podarcis liolepis, commonly known as the Columbretes wall lizard or Catalan wall lizard, is very similar to other lizards in the genus Podarcis. This species was formerly classified as a subspecies of the Iberian wall lizard, but has since been elevated to full species status.

Body Morphology

It is a slender lizard with a long tail, narrow tapered head, long thin toes, and stout legs.

Dorsal Coloration and Markings

Its coloration is variable, though it is generally grey-brown. Very subtle spots and stripes are often visible along its back and flanks, and these markings are more distinct in females.

Ventral Coloration

The underside is much lighter, ranging from cream to beige, and sometimes has a reddish tint.

Total Body Length

Adult individuals reach a total length of 15 to 20 centimeters from snout to tail tip.

Body to Tail Proportion

The body makes up roughly one third of the total length, while the tail accounts for the remaining two thirds.

Geographic Range

This lizard is found in the northeast of the Iberian Peninsula, including parts of the Pyrenees in southern France.

Elevation Range

It does not occur at elevations above 3400 meters.

Lifespan

The species has a typical lifespan of 4 to 5 years.

Sexual Maturity

Individuals reach sexual maturity in their second year.

Breeding Timing

Breeding occurs in spring, after the lizards emerge from winter hibernation.

Egg Laying Details

Females lay between 1 and 5 eggs, each measuring approximately 5 by 9 millimeters when laid, in rock cracks or under stones.

Egg Development

As the embryos develop, the eggs swell; after 8 weeks of development, when they are ready to hatch, the eggs reach about 8 by 15 millimeters in size.

Hatching Period

Hatching occurs around early July.
