The sand lizard (Lacerta agilis) is a lacertid lizard distributed across most of Europe and eastwards to Mongolia. It does not occur in the Iberian peninsula or European Turkey. Its distribution is often patchy.


Lacerta agilis argus female

The sand lizard is a sexually-dimorphic legged lizard. In northwest Europe, both sexes are characterised by lateral and dorsal strips of ocellated (eye-shaped) markings; dark patches with pale centres. Colouration varies across their European and Russian range. Males have finer markings than females, and their flanks turn bright green during the spring mating season, fading again in the late summer. Sand lizards can reach up to 25 cm (10 in) in length.[2]

It has several subspecies, the westernmost of which is Lacerta agilis agilis. In this and the other main western subspecies (L. a. argus), the dorsal stripe is thin and interrupted, or not present at all. This applies particularly to the latter subspecies, which also includes a plain red or brown-backed phase without any dorsal markings. In these two subspecies, only the flanks of the males turn green in the mating season, but in the eastern subspecies (predominantly L. a. exigua), males can be wholly green, even outside the breeding season.

Most of these lizards live in Eastern Europe. They are mostly common in Poland, Czech Republic and countries around that area. They bask on rocks in the day and when it's night they go into their holes underground. To protect themselves they pop off their tail and bite the predator.


In the UK, the sand lizard is largely restricted to lowland heathlands and sand dunes in Southern England, and to the coastal sand dunes of Northwest England and Wales. It also occupies a range of man-made habitats within these areas, including railway lines, roadsides, brownfield sites and field boundaries.

Conservation status

It is regarded as threatened and is strictly protected under UK law – as it is throughout most of Europe (it is a European Protected Species). This is in contrast to L. a. exigua, whose Russian name translates as the "common lizard". The UK Amphibian and Reptile Conservation Trust coordinates conservation action for the sand lizard, including a successful captive-breeding and reintroduction programme.


The female sand lizard lays eggs in loose sand in a sunny location, leaving them to be incubated by the warmth of the ground.
