West Virginia’s frog calls can help you tell a spring peeper from a green frog at dusk. This West Virginia frog identification guide will show you how to spot the difference between the 16 species found in the state. You’ll learn to identify frogs by their size, color, calls, and where they live.
Frogs are everywhere in West Virginia—from mountain streams to backyard ponds. But telling them apart can be tricky. This guide makes it simple. You’ll get clear steps, photos descriptions, and audio clues to ID any frog you find.
West Virginia Frog Identification Guide
This section covers all the key features you need to identify frogs in the Mountain State. We’ll break it down by family, then by individual species. Each frog has unique traits that make it stand out.
How To Use This Guide
Start by looking at the frog’s size and color. Then listen for its call. Finally, check where you found it—near water, in the woods, or in a field. Use the table below for a quick overview.
| Species | Size | Color | Call | Habitat |
|---|---|---|---|---|
| Spring Peeper | 0.75–1.5 in | Tan or brown | High-pitched peep | Wooded swamps |
| Green Frog | 2–4 in | Green to brown | Single twang | Ponds, streams |
| American Bullfrog | 3–8 in | Green or brown | Deep jug-o-rum | Lakes, large ponds |
| Gray Treefrog | 1.25–2 in | Gray or green | Trill | Forests, near water |
| Pickerel Frog | 1.75–3 in | Light brown with spots | Low snore | Cool streams |
Key Identification Features
Look at these four things first:
- Size: Measure from snout to vent. Tiny frogs are usually treefrogs or peepers.
- Color and pattern: Solid, spotted, or striped? Dorsal ridges (folds on the back) are important.
- Call: Each species has a distinct sound. Listen at night during breeding season.
- Habitat: Where did you find it? Wetlands, forests, or your garden?
Dorsal Ridges: A Key Clue
Dorsal ridges run down the back of some frogs. They look like two raised lines. Green frogs and bullfrogs have them. Leopard frogs and pickerel frogs do too, but they look different. Check the ridges to tell similar species apart.
Frog Families In West Virginia
West Virginia has four main frog families. Each family shares common traits.
Treefrogs (Hylidae)
These are small, with sticky toe pads for climbing. They call from trees or shrubs. Species include spring peepers, gray treefrogs, and mountain chorus frogs.
True Frogs (Ranidae)
Medium to large frogs with smooth skin. They live in or near water. Examples: green frog, bullfrog, pickerel frog, and leopard frog.
Spadefoots (Scaphiopodidae)
Only one species in WV: the eastern spadefoot. It has a hard “spade” on its hind foot for digging. It’s rare and mostly nocturnal.
Toads (Bufonidae)
Warty skin and short legs. They don’t need to be near water except to breed. American toad and Fowler’s toad are common.
Detailed Species Profiles
Now let’s look at each frog in detail. You’ll learn what to look for and listen for.
Spring Peeper (Pseudacris Crucifer)
This tiny frog is one of the first to call in spring. It’s only 0.75 to 1.5 inches long. Color ranges from tan to brown, with a dark X on its back. The call is a single, high-pitched peep repeated every second. You’ll hear them from wooded swamps and ponds. They breed from March to June.
Green Frog (Lithobates Clamitans)
Green frogs are common near ponds and streams. They grow 2 to 4 inches. Color is green to brown, with dark spots. The belly is white with dark lines. Dorsal ridges run down the back. The call is a single twang like a banjo string. Males have a yellow throat. They are active day and night.
American Bullfrog (Lithobates Catesbeianus)
The largest frog in WV, up to 8 inches. It’s green or brown with no distinct spots. Dorsal ridges are absent or very faint. The call is a deep “jug-o-rum” that carries across lakes. Bullfrogs eat anything they can fit in their mouth, including other frogs. They live in large, permanent water bodies.
Gray Treefrog (Hyla Versicolor)
This frog can change color from gray to green. It has a dark star-shaped patch on its back. Toe pads are large for climbing. The call is a musical trill lasting 1–3 seconds. They live in forests near water. You might find them on windows at night. They breed in temporary ponds.
Pickerel Frog (Lithobates Palustris)
Light brown with two rows of square spots. The belly is yellow or orange. Dorsal ridges are present. The call is a low, snoring sound. They prefer cool, clear streams. Their skin secretes a toxin that can irritate your eyes. Handle with care.
Northern Leopard Frog (Lithobates Pipiens)
Green or brown with round dark spots. Dorsal ridges are broken or incomplete. The call is a low, guttural snore followed by chuckles. They live in meadows and wetlands. They are less common in WV than pickerel frogs.
Mountain Chorus Frog (Pseudacris Brachyphona)
Small, about 1 inch. Gray or brown with a dark triangle between the eyes. Three dark stripes on the back. The call is a short, raspy trill. They breed in shallow pools. Found in the Appalachian region.
Upland Chorus Frog (Pseudacris Feriarum)
Similar to mountain chorus frog but with a different call. The call is a rising trill. They have a dark stripe through the eye. Found in wet meadows and ditches.
Eastern Spadefoot (Scaphiopus Holbrookii)
This is a rare, secretive frog. It has a spade on each hind foot. Color is brown or gray with two light stripes. The call is a short, explosive bleat. They only come out after heavy rains. Found in sandy or loose soil.
American Toad (Anaxyrus Americanus)
Warty skin with one or two warts per spot. The belly is spotted. The call is a long, musical trill lasting 10–30 seconds. They live in gardens, forests, and fields. They breed in shallow water.
Fowler’s Toad (Anaxyrus Fowleri)
Similar to American toad but with three or more warts per spot. The belly is plain white. The call is a short, harsh scream. They prefer sandy areas. They are less common in the mountains.
Wood Frog (Lithobates Sylvaticus)
Brown with a dark mask across the eyes. They grow 1.5 to 3 inches. The call is a quacking sound. They breed in temporary pools in early spring. They can freeze solid in winter and survive.
Northern Cricket Frog (Acris Crepitans)
Very small, 0.6 to 1.4 inches. Color varies from green to brown. A dark triangle between the eyes. The call is two clicks like stones tapping. They live near sunny ponds. They jump far for their size.
Southern Leopard Frog (Lithobates Sphenocephalus)
Similar to northern leopard frog but with a pointed snout. The call is a chuckling snore. They are rare in WV, found only in the eastern panhandle.
Eastern Narrow-mouthed Toad (Gastrophryne Carolinensis)
Not a true toad. It has a pointed head and a fold of skin across the back. Color is gray or brown. The call is a high-pitched bleat. They live under logs and leaf litter. Rare in WV.
How To Identify Frogs By Call
Listening to calls is the best way to identify frogs. Each species has a unique sound. Here’s a step-by-step guide.
- Go out at night: Most frogs call after dark. Spring and summer are best.
- Find a quiet spot: Turn off your phone. Listen for 5 minutes.
- Record the call: Use your phone’s voice memo app. Note the time and date.
- Compare to recordings: Use apps like iNaturalist or FrogID. Listen for pitch, rhythm, and duration.
- Match the call to the species: Use the table below.
| Call Type | Species |
|---|---|
| Single peep | Spring Peeper |
| Twang | Green Frog |
| Jug-o-rum | Bullfrog |
| Trill | Gray Treefrog, American Toad |
| Snore | Pickerel Frog, Leopard Frog |
| Quack | Wood Frog |
| Clicks | Cricket Frog |
Tips For Recording Calls
- Hold your phone close to the water.
- Record for at least 30 seconds.
- Note the temperature—calls change with weather.
- Use a directional microphone if possible.
Where To Find Frogs In West Virginia
Frogs live in different habitats. Knowing where to look helps with identification.
Ponds And Lakes
Look for bullfrogs, green frogs, and cricket frogs. They sit at the water’s edge. Bullfrogs are in deeper water. Green frogs are in shallower areas.
Streams And Rivers
Pickerel frogs and green frogs prefer cool, flowing water. Look under rocks and along banks. Wood frogs breed in temporary pools near streams.
Forests And Woodlands
Gray treefrogs and spring peepers live in trees. Wood frogs are on the forest floor. Look under logs and leaf litter.
Wet Meadows And Marshes
Leopard frogs and chorus frogs like open, wet areas. They call from grassy spots. American toads are also common here.
Backyards And Gardens
American toads and gray treefrogs visit gardens. Toads hide under plants. Treefrogs come to lights at night to eat insects.
Common Mistakes In Frog Identification
Even experts make errors. Here are the most common mix-ups.
- Green frog vs. bullfrog: Green frogs have dorsal ridges; bullfrogs don’t. Bullfrogs are much larger.
- Pickerel frog vs. leopard frog: Pickerel frogs have square spots; leopard frogs have round spots. Pickerel frogs have yellow bellies.
- American toad vs. Fowler’s toad: Count the warts per spot. American toads have 1–2; Fowler’s have 3 or more.
- Spring peeper vs. chorus frog: Spring peepers have an X on their back. Chorus frogs have stripes.
