Hyla orientalis

Hyla orientalis (also known as the oriental tree frog, eastern tree frog, Caucasian tree frog or Shelkovnikov's tree frog) is a frog from both Europe and Asia. Scientists saw it in Turkey, Romania, Poland, Ukraine, Georgia, Russia, Iran, Azerbaijan and Armenia. It may also live in Greece.
Scientists used to think this frog was part of "Hyla arborea" but they do not think so now.
