The Pyrenean rock lizard has a very short annual activity period, determined by the duration of snow cover and the number of daylight hours. In general, the Pyrenean rock lizard emerges when the snow melts, usually around the second half of May. It remains active throughout the summer months, with adults returning to hibernate during the second half of September and juveniles returning in the first half of October (3) (4) (5). The Pyrenean rock lizard basks in the sun to stay warm, but generally avoids the hottest parts of the day when it will retreat under stones or into vegetation (4) (5).
This species’ diet usually consists of grasshoppers, ladybirds, bees and spiders, which it catches by actively searching on the ground. The Pyrenean rock lizard typically hunts around rocky ledges near to meadows and streams where its invertebrate prey is most abundant (2).
Mating begins shortly after the emergence of the adult Pyrenean rock lizards from their wintering sites. An oviparous species, the Pyrenean rock lizard usually lays 3 eggs, although the clutch size may range between 2 and 16. The female typically lays the single clutch of eggs under medium-sized stones around the end of June to the beginning of July, and the eggs are incubated for around 34 days. Hatchlings begin to emerge from mid-August. Juvenile Pyrenean rock lizards do not reach sexual maturity until around 4 years old (2) (3) (4).
