Lilford's wall lizard is an opportunistic, omnivorous species, and its diet varies seasonally depending on the availability of food resources (3). It forages mainly for insects, such as beetles, ants, moths and butterflies, as well as insect larvae (3) (7). It has also been observed performing kleptoparasitism (3) (8). During the summer, Lilford's wall lizard feeds almost exclusively on ants, although it will also take plant matter, including fruit pulp, pollen and nectar (3) (7). As a result, Lilford's wall lizard has been identified as a potential disperser of the seeds of several rare and endemic Mediterranean plants. This behaviour makes it highly important to the Mediterranean island ecosystem, especially in the Cabrera archipelago where it is one of the only remaining terrestrial vertebrates (9).
Although Lilford's wall lizard sometimes remains active year round, most individuals will enter a state of torpor during the cold winter months. The activity levels of this species increase throughout spring and reach a peak around May, with activity in the summer months mainly concentrated in the mornings and evenings so as to avoid the intense midday heat. Lilford's wall lizard becomes gradually less active throughout the autumn and winter (3).
Not much is known about the breeding biology of Lilford's wall lizard, although breeding is thought to begin in the spring (3). The female Lilford's wall lizard lays up to three clutches each breeding season (1) (5), with each clutch containing one to three relatively large eggs (1) (3). Lilford's wall lizard frequently interacts aggressively with other lizards during the breeding season, but there is no evidence that it is particularly territorial (8).
Lilford's wall lizard is able to shed its tail to evade predators. It is preyed on by a variety of species, including genets (Genetta genetta), hedgehogs, feral cats and even other lizards. Birds, such as kestrels (Falco tinnunculus) and the Eleonora’s falcon (Falco eleonorae), are also common predators of Lilford's wall lizard (3).
