Diaterma

Diaterma is a genus of small, diurnal lizards belonging to the family Lacertidae, commonly referred to as true lizards. The name *Diaterma* derives from the Greek words *dia* (through) and *terma* (boundary), likely referencing their ability to traverse diverse habitats with ease. This genus is primarily found in the Mediterranean region, with species distributed across southern Europe, North Africa, and the Middle East.

The genus comprises two recognized species: *Diaterma boskiana* and *Diaterma petraea*. *Diaterma boskiana*, also known as the **Bosk’s wall lizard**, is native to the Iberian Peninsula, southern France, and North Africa. It is characterized by its slender body, reaching lengths of up to 15 centimeters, and a distinctive pattern of dark spots along its back. *Diaterma petraea*, or the **rock wall lizard**, inhabits rocky and arid environments in southern Europe and North Africa, often found in areas with sparse vegetation.

These lizards are well-adapted to rocky and semi-arid habitats, where they seek shelter in crevices and under rocks to avoid predators and extreme temperatures. They are insectivorous, feeding primarily on ants, beetles, and other small invertebrates. Their diet and behavior make them important components of their ecosystems, contributing to pest control and nutrient cycling.

Diaterma species exhibit a range of reproductive strategies, typically laying clutches of eggs in sandy or gravelly substrates. Females may deposit between 3 and 10 eggs, depending on the species and environmental conditions. Like many lizards, they possess the ability to detach their tails in response to predation, a process known as caudal autotomy, which allows them to escape while the tail regenerates over time.

Conservation status varies among populations, with some facing threats from habitat loss due to urbanization, agriculture, and invasive species. However, neither species is currently classified as globally threatened, though localized declines have been observed in certain regions. Efforts to monitor and protect their habitats remain important for ensuring their long-term survival.
