Other than in some other Podarcis species, the green colouration of the back of the Italian Wall Lizard (Podarcis siculus) ends at the hind legs.
And unlike some other Wall Lizards, Podarcis siculus usually has a light, unspotted throat.
Podarcis siculus is a habitat generalist and can thrive in natural and human-modified environments. 
In Italy, the subspecies Podarcis siculus siculius (1st & 2nd photo) can be found in North, Central and South-West Italy, Sicily and Sardinia.
In South-East Italy (Puglia), the subspecies Podarcis siculus campestris (last 3 photos) occurs which shows a characteristic dark vertebral stripe.
