Wikipedia
A leopard frog (sometimes called a meadow frog) can mean any frog of about 14 species within the true frog genus Lithobates. They are generally similarly colored—green with prominent black spotting that sometimes appears as a leopard pattern. They are distinguished by their distribution and certain rather subtle ecological, behavioral, morphological and genetic traits. Their range in the North-American subcontinent extends throughout temperate and subtropical North America to northern Mexico, with some species found even further south. They are also found in Europe.
