Description
Lacerta bilineata reach an average length (excluding tail) of about 13 centimetres (5.1 in), with a maximum of 40 centimetres (16 in), including tail. Their 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 2-4 pale longitudinal lines along the flanks. Also sub adults have said lines, together with several small brown spots on their backs. [2]
These lizards are territorial animals. They feed on arthropods, mainly on large insects. Sexual maturity is reached around two years, when they are about 8 cm long (excluding tail). The males fight each other, especially in the mating period, when they are very aggressive towards rivals. The mating ritual is very precise, and it starts with a bite to the base of the tail of the female. The females lay 6 to 25 eggs in a humid and warm site, such as rotting logs. The average life span of this species is about 15 years. [2]
