Description
''Lacerta bilineata'' reaches an average length (excluding tail) of about , with a maximum of , including tail. The tail may reach up to twice the body length. The average weight is about 35 grams. The body is bright green. The head is bigger in males than in females, and the males often show a blue throat. Juveniles are almost brown, with a yellowish belly and two to four pale, longitudinal lines along the flanks. Sub-adults also have these lines, together with several small brown spots on their backs.[Reptiles & Amphibiens de France]

These lizards are territorial animals. They feed on arthropods, mainly large insects. They attain sexual maturity at around two years, when they are about 8 cm long (excluding tail). The males fight each other, especially during the mating period, when they are very aggressive towards rivals. The mating ritual is precise, and starts with a bite to the base of the female's tail. The females lay 6 to 25 eggs in a humid and warm site, such as in a decomposing log. The average life span of this species is about 15 years.[
