The Leopard Frog is found in lakes, grassy ponds, marshes and wet meadows. The call of the Leopard Frog is sometimes compared to the sound of wet hands rubbing across a wet balloon. Preferred calling sites have rafts of floating vegetation for the males to cling to as they float on the surface of the water.
Females arrive at the breeding ponds approximately one week after the males start calling.
Eggs are laid a week later and are attached to submerged vegetation or are occasionally laid on the bottom of the pond. After hatching, the tadpoles take between 10 to 13 weeks to transform into froglets. By September the froglets have doubled in weight and are about 5 cm long. They will hibernate in deep pools for the winter, and can sometimes be seen on the surface mud under the water.
