Podarcis pityusensis
The Ibiza wall lizard (Podarcis pityusensis) is a species native to the Balearic Islands, primarily Ibiza and Formentera. This lizard is characterized by its green, grey, or brownish dorsal surface, a pale dorso-lateral stripe, and a robust body with coarse scales. It inhabits a variety of environments, including rocky shores, gardens, and urban areas, and its population is currently listed as endangered due to invasive snake species.

About Podarcis pityusensis
The Ibiza Wall Lizard (Podarcis pityusensis)
The Ibiza wall lizard, scientifically known as Podarcis pityusensis, is a species of lizard belonging to the Lacertidae family. It is most famously associated with the island of Ibiza in the Balearic Islands, though it has also become established in other parts of Spain. A distinct subspecies, P. pityusensis formenterae, is found on Formentera and neighboring islets, and is noted for its brighter coloration compared to its relatives on Ibiza.
Description and Habitat
This lizard typically grows to a snout-to-vent length of around 7 cm, with adults generally being slightly smaller. It possesses a robust build, a short head, and a rounded body characterized by relatively coarse, slightly keeled scales. The dorsal surface is commonly green, but can vary to grey or brownish, usually featuring a distinct pale dorso-lateral stripe. The underside is typically white, cream, grey, orange, or pink, and the throat may display darker blotches. The natural habitats of Podarcis pityusensis are diverse, including temperate shrubland, Mediterranean-type vegetation, rocky areas and shores, arable land, pastureland, plantations, rural gardens, and urban environments. They are often found in vegetated areas, particularly those influenced by human activity, and can be abundant on small islets where they may live almost exclusively on rocks.
Biology and Conservation
The diet of the Ibiza wall lizard consists mainly of small invertebrates, with a notable preference for ants when available. They also consume vegetable matter, especially during the summer months. Females generally lay a single clutch of one to four eggs, which hatch after a few weeks. Young lizards become sexually mature at about one and a half to two years of age. Unfortunately, the Ibiza wall lizard is experiencing an overall decline, with projections indicating a significant loss of its remaining habitat. The number of mature individuals has dropped considerably, leading the IUCN to classify the species as 'Endangered'. This decline is largely attributed to the introduction of invasive Horseshoe whip snakes from mainland Spain, which have caused local extinctions and pose a severe threat to the species' survival.
