摘要: The diet of Ocellated Lizard, a reptile considered as vulnerable in Europe, was studied protected area containing one the most important French populations species. It aims to describe composition and its temporal variation but also identify differences between age classes. A sample 221 scats was collected from May September 2010 seven different sites studied (Crau plain, France). From 4029 items analysed, 156 taxa were identified. is composed by Coleoptera (26.7 %), Orthoptera (23 Hymenoptera (19.3 %) fruits (17.1 %). Dung beetles represent only 2.1 % prey, which surprising for such heavily grazed area. different month another (χ2 = 943.173, df 20, p < 0.001) classes exist (V 572, 0.001). Adult lizards eat more than juveniles August 80.349, 1, The prey richness not adults (Z = 1.839, > 0.05). Finally, characteristics in Crau plain are discussed compared other Iberian Lizard
