Louisiana’s bayous and swamps are practically synonymous with frogs and their constant chorus. If you’re wondering about the most common frogs in louisiana, you’ve come to the right place. These amphibians are everywhere here, from your backyard to the deepest marsh. Knowing which ones you’re hearing or seeing can make your time outdoors much more interesting.
Frogs play a huge role in Louisiana’s ecosystem. They eat tons of insects and serve as food for birds, snakes, and fish. Plus, their calls tell you a lot about the health of a wetland. Let’s jump right into the species you’ll most likely encounter.
Most Common Frogs In Louisiana
This list covers the frogs you’ll see and hear most often across the state. Each one has unique features and behaviors that make them easy to spot once you know what to look for.
Green Treefrog
The Green Treefrog is probably the most recognized frog in Louisiana. You’ll find them clinging to windows, porch lights, and plants near water. They are bright green with a white or yellow stripe down each side.
- Size: 1.25 to 2.5 inches long
- Call: A loud, nasal “queenk-queenk” or “reeenk”
- Habitat: Trees, shrubs, and buildings near ponds and swamps
- Activity: Mostly at night, especially after rain
These frogs are great for pest control. They eat moths, crickets, and spiders that gather around lights. If you have a porch light, you’ll almost certainly see them.
American Bullfrog
The American Bullfrog is the giant of Louisiana frogs. They can grow up to 8 inches long and weigh over a pound. Their deep, resonant “jug-o-rum” call is a classic sound of southern wetlands.
- Size: 3.5 to 8 inches
- Call: A low, bellowing “rumm, rumm”
- Habitat: Permanent ponds, lakes, and slow-moving rivers
- Diet: Almost anything they can fit in their mouth, including small birds and snakes
Bullfrogs are ambush predators. They sit still in shallow water and wait for prey to come close. You’ll often see only their eyes and nose poking above the surface.
Southern Leopard Frog
Southern Leopard Frogs are easy to identify by their spots. They have two or three rows of dark spots on their back and a distinct white line on their upper lip. They are more slender than bullfrogs.
- Size: 2 to 3.5 inches
- Call: A short, guttural chuckle or series of croaks
- Habitat: Grassy areas near water, ditches, and marshes
- Behavior: They jump long distances to escape danger
These frogs are common in both rural and suburban areas. You might see them crossing roads on rainy nights. They are a key food source for wading birds like herons.
Bronze Frog
The Bronze Frog is actually a subspecies of the Green Frog. They have a bronze or coppery color on their back and a green face. Their call sounds like a loose banjo string being plucked.
- Size: 2 to 4 inches
- Call: A single, twangy “gunk” or “thrum”
- Habitat: Swamps, bayous, and forested wetlands
- Distinguishing feature: Two prominent ridges (dorsolateral folds) down their back
Bronze Frogs are shy and will quickly dive into the water if you approach. They are most active during warm months and can be found basking on logs.
Spring Peeper
Spring Peepers are tiny frogs with a huge voice. They are only about an inch long but their high-pitched “peep” can be heard from half a mile away. They are the first frogs to call in late winter.
- Size: 0.75 to 1.25 inches
- Call: A single, clear “peep” repeated every second
- Habitat: Wooded areas near temporary ponds and swamps
- Color: Tan or brown with a dark X-shaped mark on their back
These frogs are hard to see because they are so small and well-camouflaged. But you can’t miss their chorus on a warm February evening. They signal the start of frog season in Louisiana.
Cajun Chorus Frog
The Cajun Chorus Frog is a small, secretive species found mostly in southern Louisiana. They are named after the region’s Cajun culture. Their call is a slow, raspy trill that sounds like running a finger over a comb.
- Size: 0.75 to 1.25 inches
- Call: A slow, ascending trill lasting 1-2 seconds
- Habitat: Marshes, ditches, and flooded fields
- Appearance: Brown or gray with three dark stripes down the back
This species was only recently recognized as distinct from the similar Upland Chorus Frog. They breed in shallow, temporary water bodies after heavy rains.
Pig Frog
Pig Frogs get their name from their call, which sounds like a pig grunting. They are large, aquatic frogs that live in deep swamps and marshes. They are closely related to bullfrogs but have a different call.
- Size: 3 to 6 inches
- Call: A low, grunting “r-r-r-rum” like a pig
- Habitat: Deep, permanent water with lots of vegetation
- Diet: Fish, crayfish, and other frogs
Pig Frogs are more aquatic than bullfrogs. They rarely leave the water. Their legs are prized for frog legs in Cajun cuisine.
Eastern Narrow-Mouthed Toad
Despite the name, this is actually a frog, not a toad. They have a small, pointed head and a fold of skin behind their eyes. Their call is a loud, buzzing “beeeeee” that lasts several seconds.
- Size: 1 to 1.5 inches
- Call: A high-pitched, insect-like buzz
- Habitat: Moist soil under logs, leaf litter, and near ponds
- Appearance: Gray or brown with a light belly
These frogs are secretive and spend most of their time underground. They come out to breed after heavy rains. They eat ants and termites almost exclusively.
Southern Cricket Frog
Southern Cricket Frogs are tiny, warty frogs that look like miniature toads. They have a distinctive dark triangle between their eyes. Their call sounds like two small stones being clicked together.
- Size: 0.5 to 1 inch
- Call: A rapid, metallic “click-click-click” like a cricket
- Habitat: Edges of ponds, streams, and ditches
- Behavior: They are very jumpy and hard to catch
These are the smallest frogs you’ll commonly see in Louisiana. They are often found in large numbers along muddy banks. They are an important food source for many predators.
Gulf Coast Toad
The Gulf Coast Toad is a true toad, with dry, warty skin. They are common in gardens and yards across Louisiana. Their call is a long, musical trill that lasts 5-10 seconds.
- Size: 2 to 4 inches
- Call: A high-pitched, continuous trill
- Habitat: Urban areas, gardens, and forests
- Defense: They have large parotoid glands that secrete a mild toxin
These toads are beneficial in gardens because they eat slugs, snails, and insects. They are most active at night. You’ll often find them under porch lights or in flower beds.
Where To Find Frogs In Louisiana
Frogs are everywhere in Louisiana, but some places are better than others for spotting them. Here are the best habitats to check.
Backyard Ponds And Gardens
Even a small pond will attract frogs. Green Treefrogs and Gulf Coast Toads are common visitors. Provide plenty of plants for cover and a shallow area for them to sit.
- Add a small water feature
- Leave leaf litter for hiding spots
- Avoid using pesticides
Swamps And Bayous
These are the classic frog habitats. You’ll hear Pig Frogs, Bronze Frogs, and Bullfrogs here. Go at night with a flashlight to see their eyes shining back at you.
- Visit after sunset
- Listen for different calls
- Look for frogs sitting on lily pads or logs
Temporary Ponds And Ditches
After heavy rain, temporary pools form in fields and ditches. These are breeding grounds for Spring Peepers and Cajun Chorus Frogs. They only last a few weeks, so act fast.
- Check after spring rains
- Look for egg masses attached to grass
- Listen for choruses at dusk
How To Identify Frogs By Their Calls
Learning frog calls is the best way to know what’s around. You don’t need to see them. Here is a simple guide to the most common calls.
Green Treefrog
Sounds like a loud, nasal “queenk” or a short bark. Often repeated in a series.
American Bullfrog
A deep, resonant “jug-o-rum” that carries across the water. Males call from shallow water.
Spring Peeper

Eastern Narrow-Mouthed Toad
