Northern Leopard Frog

Back to the sheet

This green frog with pronounced brown spots is a Northern Leopard Frog. Look at the folds in the skin that begin behind the eye and extend down the back. The white, rather than yellow, belly distinguishes it from the Pickerel Frog with which it is sometimes confused. The Northern Leopard Frog lives in watercourses colonized by surface plants and grasses. The adult may measure up to 10 cm long. In the spring, the female lays more than 3,000 eggs, of which only a small percentage develop into tadpoles and then into frogs. This species is found in all the provinces of Canada, but populations are more vulnerable in the west. In British Columbia, they are classed as endangered. The destruction of their habitats, pesticides and acid rain are some of the factors that have affected the species since the 1970s. This whole specimen, preserved in alcohol, was collected in Laval, in Quebec, in 1936.
