Here are three pics of western green lizards (Lacerta biliniata). They too have had an early start.This is a male just maturing into his adult form.He already has a blue head.This species varies enormously and care must be taken when sexing the animals as females can also have blue heads and males can be finely spotted like many females.
Below is a plain green female.She looks like most males.
And here is a mottled female.It is basically a juvenile colour form that is retained by a third of the females present in this particular colony.
