Western Green Lizard

Lacerta bilineata

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The western green lizard is a lizard of the family Lacertidae. Until recently it was regarded as a subspecies of Lacerta viridis, under the name Lacerta viridis bilineata, but the genetic differences found, which make hybrids less fertile, have led to the two being treated as separate species.

Fun facts

  • reproducciónThe males develop a deep blue throat in the breeding season, a visual signal of genetic quality to the females.
  • In the breeding season the male's throat turns an intense turquoise blue, and in some populations the female's does too, a feature that has been linked to signalling physical condition.
  • In Spain its distribution is limited to a strip across the north of the peninsula, and its populations depend on the hedgerows and margins between fields, a habitat in continual decline.
  • It was separated from the eastern green lizard as a species of its own in the 1990s: for decades the two were regarded as a single widespread European species.
