Rana sphenocephala

Southern Leopard Frogs
are large, slender frogs, growing up to five inches long.
They are green and brown with large dark spots on their back
and sides. Leopard frogs have
light-colored dorsolateral ridges (raised lines on their
backs). They also have a light stripe along their
jaw. Southern Leopard Frogs
can be found just about anywhere there is shallow water,
including lakes, ponds, marshes,
and streams. Denny Cannon, The Frogs

Leopard frogs are nocturnal, so they are most active at night. During the day, they hide among plants on the shore. If they are startled, they will leap into the water, making a sharp turn underneath the surface. They will come back up hidden among some plants.
The breeding season for Southern Leopard Frogs is March to June. Female frogs will lay egg masses of up to 4,000 eggs in shallow water. Usually they attach to plant stems.
Tadpoles hatch from the eggs and eat algae and other small organisms in the water, including small insect larvae and water fleas. Tadpoles will transform to adult frogs by late Spring or early Summer.
After mating, adult frogs will wander away from the water, into woods or fields, hiding among plants or under logs. As Summer ends, frogs return to the water.
Adult Southern Leopard Frogs eat a wide variety of prey, including earthworms, spiders, centipedes, and many types of insects.

Predators of leopard frogs include Raccoons, Virginia Opossum, large fish, snakes, turtles, larger frogs, and herons. Tadpoles and eggs are especially vulnerable and may be eaten by insects, turtles, leeches, fish, salamanders, or crayfish.
Southern Leopard Frogs can leap several feet.

Relationships in Nature:
Relationship to Humans:
Southern Leopard Frogs are raised and eaten by humans. When you see "frog legs" on a menu, it is most likely a Southern Leopard Frog. These frogs are also used in large amounts in biology classes for dissecting. Scientists have become concerned about too many frogs being used for this purpose.
Southern Leopard Frogs are also very important in the wild. They eat huge amounts of pesky and dangerous insects, such as mosquitos.
