On the hottest days they restrict their movement to early in the morning or late evening remaining hidden during the main heat of the day and so regulating their body temperature. They prefer damp meadows and cool hillsides including seasonally flooded areas, abandoned fields, hedges and land with abundant herbaceous vegetation.

The Western Three-toed Skink feeds mainly on insects – crickets, grasshoppers, caterpillars and spiders and worms etc.

Between March and June the breeding season begins. Between two and three months after mating, females give birth to 1 – 12 fully formed young. They are ovoviviparous (able to incubate the eggs inside the female)

  • Conservation Status: LC. Least Concern – The IUCN has listed the western three-toed skink as being of “Least Concern” because of its wide range and the fact that it is very common in some parts of its range. It is nevertheless threatened by changes in agricultural practices resulting in degradation of its habitat. In some areas it is persecuted because it is mistakenly thought to be venomous.
  • Distribution: Portugal, Spain, the Mediterranean coast of France, NW Italy.
