Leopard frogs eat varied diets of ants, flies, worms, smaller frogs, and even small birds and snakes. They may also eat other frogs of their own species. Leopard frogs hunt by sitting very still and waiting for prey to appear before surprising the prey by suddenly pouncing and trapping it in their mouths. Leopard frogs are carnivores, which means that they eat only other animals.

There are at least 14 different species that are known as leopard frogs. Common species include the island leopard frog, plains leopard frog, northern leopard frog and southern leopard frog. They are all very similar in their eating patterns and appearance but are distinguished by their distribution and certain genetic traits. Their lifespan is typically between 2 and 4 years in the wild.

All species of leopard frogs are predominantly green in color with black spots. Their undersides are pale cream. Some species are smaller than others, but a well-known species, the northern leopard frog, can reach up to 5 inches in length. Female frogs are typically larger than males of the same species. Leopard frogs can be found throughout temperate and sub-tropical regions of North America, reaching as far south as northern Mexico. Some species are also seen in Europe.
