Rana arvalis
They are small frogs, characterized by an unspotted belly, a large, dark ear spot and - often, not always - a pale stripe down the center of the back. They are generally described as a reddish-brown, but can also be yellow, gray, or light olive[2]. Their bellies are white or yellow and they have a "bandit-like" black stripe going from their nose to their ears. They vary from 5.5 to 6 cm long but can reach up to 7 cm in length and their heads are more tapered than those of the European Common frog, (Rana temporaria). The skin on their flank and thigh is smooth and the posterior part of their tongue is forked and free. They have horizontal pupils, their feet are partially webbed and their back legs are shorter than those of other species of frogs. The males are different from the females because of the nuptial pads on their first fingers and their paired guttural vocal sac. (Wikipedia)
The frogs can be found inhabiting an area stretching from the lowlands of Central and South Europe to Siberia.
