This species has experienced range-wide declines throughout the western states and Canada. They can live from 6-8 years in captivity. ... Video: A leap for conservation: In the summer of 2019, hundreds of endangered northern leopard frogs hopped back into the wild at Columbia National Wildlife Refuge in central Washington. It eats insects like beetles, ants, and leafhoppers. The lifespan of a northern leopard frog is 5-8 years. Newly metamorphized frogs will attempt to disperse from the breeding area, moving along drainages and across dry land. It is the state amphibian of Minnesota and Vermont. Northern leopard frogs live in an area with 68 to 75 °F, although a temperature drop at night is beneficial (down to about 60 °F 16 °C). However, when someone asked me about the differences, I couldn’t give a clear and precise answer to her question. It has a white to cream-colored underside and distinct, unbroken paler dorsolateral ridges, or fins, along both sides of the back. Tadpoles are generalist herbivores, eating algae, plant tissue, organic debris, and probably small invertebrates.

They lay their eggs in still, permanent water in areas exposed to sunlight, usually attaching the eggs to vegetation just below the surface of the water. Adult and juvenile northern leopard frogs eat small invertebrates, spiders, mollusks, and crustaceans. Endangered and threatened wildlife and plants; 90-day finding on a petition to list the northern leopard frog (Lithobates [=Rana] pipiens) in the western United States as Threatened. It is the state amphibian of Minnesota and Vermont. In 2006 eight environmental organizations submitted a petition to the U.S. Males make a short, snore-like call from water during spring and summer. Rana pipiens from North and Central America was once considered to be one wide-ranging species with considerable geographic variation (Moore, 1944).
