Wall lizards species are hard enough to identify as adult let alone when small juveniles so hopefully range may help.Both found in Catalonia . 1st photo from the centre of Parc natural de Sant Llorenc del Munt i Obag. 2nd photo from further north at Guilleries Savassona NP. P.liolepis or P.muralis. Weather was cold and dull and both found under rocks. No adults seen. Bad light, wet and tired = poor quality photo's
