Remarks: Specimens reportedly exhibiting atypical color patterns for Massachusetts were collected as early as 1915 from Cuttyhunk Island. The species was harvested in states like Minnesota, Vermont and Connecticut for use in classroom experiments. Once experiments were completed, teachers routinely released the surviving tadpoles into the wild.
Found in streams, lakes, ponds, and wet prairies. Often called the "meadow frog" due to its wandering well away from water in the summer time. Individuals may congregate under submerged logs or rocks during the winter. Lays eggs from March to May; tadpoles transform in late June to August.
