What frogs are found in Alaska?
Alaska has four native species: the wood frog (Rana sylvatica), Columbia spotted frog (Rana luteiventris), northern leopard frog (Rana pipiens), and the boreal chorus frog (not always confirmed). The wood frog is most widespread, surviving even above the Arctic Circle. For a full species list, visit ourfrog identification hub.

What do these frogs typically eat?
Alaska frogs are insectivores. Their diet includes beetles, flies, mosquitoes, ants, caterpillars, and spiders. Wood frogs also eat snails and small crustaceans. They grab prey with their sticky tongues. Learn more about foraging habits in ourAlaska frog diet guide.
Where in Alaska are you most likely to see frogs?
Look for frogs near freshwater: shallow ponds, lake edges, slow streams, and bogs. The wood frog is common in interior and southcentral Alaska, especially around Fairbanks and Anchorage. Spotted frogs favor wetlands in the southeast and southcentral regions. Check ourAlaska wildlife sectionfor specific habitat details.
What is the best season for frog sightings?
Late spring through summer (May to August) is prime viewing. Frogs emerge after thaw, breed in April to June, and are most active on warm, damp days. You'll hear wood frogs' quack-like calls near breeding ponds. Timing varies by region; southcentral frogs appear earlier than interior ones.

How can you tell Alaska frogs apart from each other?
Wood frogs are brown with a dark mask behind the eye and a white belly. Columbia spotted frogs have black spots on a greenish-brown back and a pale stripe along the upper lip. Northern leopard frogs have large dark spots with light borders. Boreal chorus frogs are small with three dark stripes down the back.
What specific insects make up their diet?
Beetles and flies dominate. Wood frogs eat ground beetles, leaf beetles, and fly larvae. Mosquitoes, ants, and spiders are also common. Tadpoles feed on algae and decaying plant matter. Adult frogs may occasionally eat smaller amphibians or earthworms if the opportunity arises.
