Although usually coloured green, Leopard Frogs are frequently brown. The dark spots covering the back and sides are generally roundish in shape, and are always outlined in yellow or white. (This feature distinguishes the Leopard Frog from the similarly marked Pickerel Frog). The prominent dorsolateral folds are light-coloured, extending the full length of the back.
Northern Leopard Frogs hibernate underwater, sitting on the bottom beneath a submerged log or concealed under a light layer of silt. In early spring they move to shallower water to breed. Their advertisement calls sound like chuckling snores, often followed by hoarse clucks and croaks.
Throughout the summer months in the Algonquin Highlands, Leopard Frogs can be found in open grassy areas, often well away from water. By absorbing moisture from dew or damp soil through their skin, they are able to tolerate these dry conditions.
