Lithobates pipiens
medium-sized 5-9 cm frog Green to light brown in colour Dark brown or black roundish spots, outlined in yellow, scattered on back and side. White line on upper lip is usually quite noticeable. 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. 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. Description of call: A series of chortles and chuckles, followed by wet hands rubbing a balloon, or a long snore followed by a chuckling call; "chuck, chuck, chuck"
Leopard Frogs utilize many aquatic habitats, such as marshes, ponds, lakes, rivers, or streams (Green and Pauley, 1987). During warmer months, these frogs may leave the water and venture into fields or pastures to forage. Their diet consists of terrestrial invertebrates, such as spiders and insects. Leopard frogs, like many other amphibians, are opportunistic feeders.
