The Dark-Spotted Frog lives in meadows, different types of forests, bushlands and in desert (Turkmenia). Within these landscape types, it inhabits different types of water bodies, including river pools, channels, lakes, ponds, swamps, ditches and rice fields. In Turkmenia, the frog is strictly associated with riparian, overgrown parts of ponds, channels and irrigation ditches, whereas in the Far East it regularly occurs 2-15 m from water. In general, however, this frog displays a high site-fidelity. As a rule, it uses stagnant waters, rarely occurring in the shallows of rivers, covered with dense vegetation. It should be noted that in Turkmenia this species lives mainly separately from its relative, the autochthonous Marsh Frog (Rana ridibunda). Only in few ponds do these two species co-occur.
Life History, Abundance, Activity, and Special Behaviors
Tadpoles consume primarily plants (algae etc.). Adults primarily eat spiders, terrestrial insects and other invertebrates. Vertebrates (fish fry, amphibians etc.) are rarely eaten. Feeding does not cease during the breeding season.
