European wall lizard
About This Species
European wall lizards were introduced to Southern Vancouver Island in 1967 and have slowly been spreading north. They are found along the Eastern coast of Vancouver Island from Victoria to Campbell River, and on Denman Island and South Pender Island. There have been reports on the mainland from Abbotsford, West Vancouver, and Osoyoos, but it is unknown if they are established in these areas. Without human assistance, they typically spread at a rate of 100 m/year, so these lizards are thought to spread by hitchhiking on vehicles, shipments of produce and plants or released by people who keep them as pets.
European wall lizard are omnivorous, feeding on a variety of insects, spiders, and other invertebrates, as well as fruits. They can reproduce up to three times per year during the spring and summer, and females will lay 3-11 eggs each time. These eggs are carefully hidden under rocks or pieces of wood on the ground, where they incubate for up to a month before hatching.
European wall lizards can often be found basking on rocks or tree trunks in the full sun. They do well in areas modified by humans, like backyards, railways, and roadsides. They typically hibernate from November to March, but may become active on sunny days.
How to Identify
European wall lizards grow up to 23 cm long, though size varies between the sexes, with female lizards being slightly smaller than males. They have brown backs covered with green splotches, and males have blue spots running down their sides. Their bellies are cream coloured with brown spots that fade towards the back of the lizard and become darker towards the throat. Their tail is twice as long as their body.
European wall lizards look similar to native Northwestern alligator lizards (Elgaria coerulea). European wall lizards have longer limbs and toes, and may have green or blue colouration, while Northwestern alligator lizards are more drab.
