15 Types of Frogs in West Virginia (And How to Identify Them)
September 15, 2026
On a warm February night in a West Virginia lowland, a frog barely the size of a paperclip can be heard singing from half a mile away, long before the first crocus breaks ground. That tiny performer is the spring peeper, and it’s just one of the 15 types of frogs in West Virginia that wildlife biologists have documented across the state’s mountains, wetlands, and river valleys. From thumbnail-sized cricket frogs to bullfrogs the size of a dinner plate, these amphibians occupy nearly every wet habitat the Mountain State has to offer.
This guide walks through each of West Virginia’s native frog and toad species, covering how to tell them apart by color, size, call, and where they’re most likely to turn up. Whether you’re exploring a vernal pool in the Eastern Panhandle or listening to a chorus along the Ohio River, the table below offers a quick-reference starting point before diving into the details of each species.
| Common Name | Family Group | Adult Size | Where to Find in West Virginia | Listen For |
|---|---|---|---|---|
| Blanchard’s Cricket Frog | True Frog Relative | Under 1.5 inches | Western border counties | Clicking, marble-like clicks |
| Eastern Cricket Frog | True Frog Relative | Under 1.5 inches | Ponds and stream edges statewide | Rapid clicking calls |
| Eastern American Toad | True Toad | 2-4 inches | Statewide, including yards | Long musical trill |
| Fowler’s Toad | True Toad | 2-3.5 inches | Sandy or gravelly soils | Buzzy, nasal trill |
| Cope’s Gray Treefrog | Treefrog | 1.25-2 inches | Wet woodlands, porches | Fast, harsh trill |
| Gray Treefrog | Treefrog | 1.25-2 inches | Wooded ponds statewide | Slower, melodic trill |
| Mountain Chorus Frog | Chorus Frog | Under 1.5 inches | Appalachian foothills | Raspy, repeated call |
| Spring Peeper | Chorus Frog | 1-1.5 inches | Swamps and vernal pools | High-pitched peeping |
| Upland Chorus Frog | Chorus Frog | Under 1.5 inches | Grassy wetlands, floodplains | Rising trill |
| American Bullfrog | True Frog | 3.5-6 inches | Permanent ponds, lakes statewide | Deep “jug-o-rum” |
| Green Frog | True Frog | 2-4 inches | Streams, marshes statewide | Banjo-string plunk |
| Pickerel Frog | True Frog | 1.75-3 inches | Cool streams, meadows | Low, snoring growl |
| Northern Leopard Frog | True Frog | 2-4.5 inches | Western half of the state | Chuckling, snore-like call |
| Wood Frog | True Frog | 1.5-3 inches | Forested vernal pools | Clucking, quacking chorus |
| Eastern Spadefoot | Spadefoot Toad | 2-3 inches | Sandy soils, rarely seen | Low, grunting call |
Pro Tip: Most of West Virginia’s frogs are far easier to identify by ear than by sight. Visit a wetland at dusk in spring and let the calls guide your search before switching on a flashlight.
1. Blanchard’s Cricket Frog
The Acris blanchardi is one of the smallest and least frequently encountered frogs in West Virginia. According to the state’s official checklist, Blanchard’s cricket frog occurs along the western edge of the state, where its range overlaps with populations found further west into Illinois and the broader Ohio Valley.
This species belongs to a group of frogs so small they’re often mistaken for insects hopping through streamside grass. They range in size from the tiny cricket frog to the bullfrog, illustrating just how much variation exists among the state’s 15 native species. Because of its restricted range and secretive habits, Blanchard’s cricket frog is considered one of the harder species to document during a typical outing.
2. Eastern Cricket Frog
The eastern cricket frog, Acris crepitans, is the more widespread of West Virginia’s two cricket frog species. It shares the same diminutive build as its Blanchard’s cousin but ranges more broadly across the state’s ponds, ditches, and slow-moving stream edges.
Anyone who has spent time exploring frog populations in neighboring Virginia will recognize this species immediately, since its range extends across much of the mid-Atlantic and Appalachian region. Cricket frogs are active during the day, unlike many of West Virginia’s other frog species, which makes them one of the few native frogs you might actually spot before you hear them.
3. Eastern American Toad
The eastern American toad (Anaxyrus americanus) is one of the most familiar amphibians in the state. They can be found throughout Pennsylvania and they are one of the most common amphibian species in West Virginia. Its rough, warty skin is primary brown in color but can have some black, gray, or red coloration, and it turns up almost anywhere there’s moist soil to burrow into.
The American toad is mainly nocturnal and is most active when the weather is warm and humid. During the winter, the toad will burrow deep into the ground below the frost line. Its call is distinctive: a high musical trill which can last upwards of 30 seconds. According to the West Virginia Encyclopedia, this species and Fowler’s toad are the state’s most commonly encountered toads, sharing habitat with the far more secretive spadefoot.
Key Insight: There’s no strict biological line separating frogs from toads. As a general rule, frogs have smooth, moist skin and spend more time in water, while toads have drier, warty skin built for a life mostly spent on land.
4. Fowler’s Toad
Fowler’s toad (Anaxyrus fowleri) looks so similar to the American toad that most people rely on sound rather than sight to tell them apart. Fowler’s Toads look almost exactly like American toads but their call is very different; a buzzy trill that some say sounds like a crying baby.
Fowler’s toad tends to favor sandier or looser soils than its American cousin, which makes river bottoms and disturbed ground good places to search. If you’re trying to sort out the finer points of frog versus toad classification across the region, the full breakdown of frog diversity worldwide offers useful context on how these two closely related species fit into the bigger picture.
5. Cope’s Gray Treefrog
Cope’s gray treefrog (Dryophytes chrysoscelis, also listed as Hyla chrysoscelis) is a small, well-camouflaged treefrog documented in locations such as Fayetteville, West Virginia. Individuals can be found around both temporary and permanent water bodies. They are usually found living in or around wet woodlands like swamps, ponds, lakes, and mixed or deciduous forests.
This species is nearly indistinguishable from the standard gray treefrog without listening closely. Some larger frog species have been observed as predators of Cope’s gray tree frogs, probably because of their very small size. They avoid their predators through their nocturnal activity and cryptic adaptation. According to Snaketracks, its range also extends into states as far south as Alabama and Florida, making it one of the more widely distributed treefrogs in the eastern United States. Anyone comparing frog diversity across the Appalachians will find similar populations documented in guides to frog species in North Carolina.
6. Gray Treefrog
The gray treefrog (Dryophytes versicolor) rounds out West Virginia’s pair of near-identical treefrogs. The grey treefrog may range in color from green to brown to grey. During the day, they may be found sleeping on tree branches or leaves. Their toes have a sticky pad which allows them to easily climb vertically up windows, siding, trees; etc.
Breeding females lay impressive numbers of eggs each season. Female grey tree frogs may lay 1,000-2,000 eggs in clusters of 10-40. Tadpoles can be distinguished by their redish-orange tails. Males produce a short melodic trill that lasts only a second, and will generally call on warm and humid evenings between April and July. If you enjoy spotting wildlife clinging to bark and tree trunks around your property, the woodpeckers found across West Virginia make an interesting companion search on the same walk.
Common Mistake: Don’t try to separate Cope’s gray treefrog from the standard gray treefrog by color or size alone. The only reliable field method is listening to the call speed, since the two species are otherwise nearly identical in appearance.
7. Mountain Chorus Frog
The mountain chorus frog (Pseudacris brachyphona) is a small chorus frog closely tied to West Virginia’s Appalachian terrain, and its range reflects the rugged, forested foothills the species name describes. It belongs to the same genus as the spring peeper and upland chorus frog, all of which rely on temporary pools and roadside ditches for breeding rather than large permanent lakes.
Because chorus frogs spend most of the year hidden in leaf litter and dense vegetation, spotting one outside of the breeding season is uncommon. Naturalists exploring the mountain forests for other small, hidden wildlife often turn their attention to the region’s diverse insect life as well, including the wide range of beetle species found across the Appalachians.
8. Spring Peeper
No frog announces a West Virginia spring quite like the peeper. The spring peeper is one of West Virginia’s smallest frogs measuring from 1 inch to 1-1/2 inches, and it can be distinguished by its dark colored “X” across its back. Its chorus of a shrill high pitched call can be heard from up to a half mile away.
Peepers are among the very first frogs to call each year. According to West Virginia Explorer, spring peepers will herald the return of light and warmth in central Appalachia in late February and early March, with choruses often beginning in late February in low-lying valleys even though their song may not be heard in the uplands until late March. This same species delights listeners far beyond West Virginia’s borders, including populations documented in Connecticut’s native frog community. Like most tree frogs, the spring peeper is nocturnal and loves to hunt ants, spiders and other small insects during the evening.
Pro Tip: If you hear a high, sleigh-bell-like chorus near a wetland in late winter, you’re almost certainly listening to spring peepers rather than any other West Virginia frog species, since no other native frog calls quite that early or that loudly for its size.
9. Upland Chorus Frog
The upland chorus frog (Pseudacris feriarum) is listed as an uncommon species on West Virginia’s official amphibian checklist, meaning it’s present but rarely seen outside of its brief breeding window. Like its chorus frog relatives, it favors grassy wetlands, floodplain pools, and roadside ditches rather than large open water.
Its range extends well beyond the Mountain State into much of the Midwest and central United States, overlapping with chorus frog populations documented across Iowa’s wetlands and prairie potholes. Distinguishing this species from the mountain chorus frog and spring peeper usually comes down to call pattern and precise habitat rather than appearance alone, since all three are small, similarly patterned frogs.
10. American Bullfrog
The American bullfrog (Lithobates catesbeianus) is the giant of West Virginia’s frog world. The American Bullfrog is the largest frog in the state. American bullfrogs are the largest true frogs existing in North America. They’re found near permanent bodies of water such as large ponds, streams, and lakes statewide.
Males develop a striking feature at maturity: once the males of the species reach sexual maturity, their throats turn bright yellow. Bullfrogs are frequently confused with green frogs, but they are very similar to Green Frogs but they don’t have a dorsal ridge down their back; it wraps around their tympanum instead. As a top predator among the state’s amphibians, American bullfrogs are a predatory species and they endanger some other species of frogs as a result. Their range and predatory habits mirror populations found much further south, including those documented in guides to frog species in Mississippi.
11. Green Frog
Also called the bronze frog, the green frog (Lithobates clamitans) is one of West Virginia’s most frequently seen amphibians. This frog is usually found living in, around, or along marshes, bogs, sloughs, slow-moving streams, and rivers, though it moves into meadows and wooded areas in the rainy periods of the year.
Color varies considerably within the species. Dorsally, green frogs are mostly green, yellow-green, brown, brownish green, or olive in color, and there are some rare individuals that are colored blue. Their bellies are usually any bright shade from yellow to white. Irregular dark spots can be noticed on their backs, there are transverse bands on the legs, and their toes are extensively webbed. The call is unmistakable once you know it: the Green Frog produces a single note call that is relatively easy to identify, sounding like a plucked banjo string that is often repeated. These frogs are opportunistic feeders, and they use a “sit and wait” approach, eating almost anything they can fit inside their mouth, including spiders, insects, fish, crayfish, snails, slugs, small snakes, and even other frogs. This species’ broad range extends south into states like Alabama, where similar populations thrive.
12. Pickerel Frog
The pickerel frog (Lithobates palustris) holds a unique distinction among West Virginia’s amphibians. West Virginia has a single poisonous frog species – the pickerel frog, according to Animal Spot’s regional species guide. Its skin secretes mild toxins that can irritate the skin of predators, and by extension, human hands.
Physically, the pickerel frog is a medium to large sized frog, and its dorsal ridge runs down from its eye to its back with rectangular boxes inside, a pattern that separates it from the similarly built leopard frog. This species also connects naturally to broader discussions of poisonous frog species found around the world, even though its toxin is far milder than that of any tropical species.
Important Note: The pickerel frog’s skin secretions are mild compared to true poison frogs, but they can still irritate sensitive skin, eyes, or open cuts. Always wash your hands after handling any wild frog, and avoid keeping pickerel frogs in the same container as other amphibians.
13. Northern Leopard Frog
The northern leopard frog (Lithobates pipiens) is a large, boldly patterned species with a more limited range within the state than many of its relatives. The Northern Leopard Frog is a medium to large species of semi-aquatic frog found in the western half of the state.
They vary in color from dark brown to slim green with fairly large spots all over their body, making them easy to distinguish from the pickerel frog’s more rectangular markings once you know what to look for. Populations further west share habitat characteristics with frogs documented in states such as Nebraska’s wetlands and river systems, reflecting how widely this species ranges across the central and eastern United States.
14. Wood Frog
The wood frog (Lithobates sylvaticus) is famous for one of the most remarkable survival strategies in the animal kingdom. They have adapted to cold climates by being able to freeze over the winter. Their breathing and heartbeat stop, and their bodies produce a type of antifreeze that prevents their cells from bursting. In the spring, they thaw and begin feeding again.
According to the West Virginia Division of Natural Resources, February 20 marks the earliest reported date observed for breeding activity in West Virginia, and congregation at the breeding pools begins with the first several consecutive nights at temperatures above freezing. The tadpoles grow quickly, with metamorphosis completed by early June. Physically, wood frogs range in length from 1.5 to 3 inches, are unspotted with dorsal coloration varying from light pink to tan, gray, and even nearly black, and the best field mark is the black mask which extends across the cheek and through the eye. After breeding, they are often found in the woods, far away from any water bodies, hunting insects and other small invertebrates, including the many caterpillar species found throughout the Appalachian forests. Researchers have even found that wood frogs seem to be able to recognize their family, with tadpole siblings seeking each other out and grouping together.
15. Eastern Spadefoot
The eastern spadefoot (Scaphiopus holbrookii) is the most elusive of West Virginia’s 15 frog and toad species. The spadefoot toad is seldom seen because of its secretive nature of remaining underground, only surfacing to mate and deposit eggs during heavy rains.
This burrowing lifestyle puts West Virginia’s spadefoot in the same ecological niche as desert-adapted spadefoot relatives found in arid states, including several species profiled in guides to frog and toad species in Arizona. Its rarity in the field record reflects genuine scarcity, not just difficulty of detection, and any confirmed sighting is considered a notable find among West Virginia herpetologists.
Pro Tip: The best window for spotting an eastern spadefoot is during or immediately after a heavy summer downpour, when rising groundwater triggers a brief, synchronized emergence for breeding.
West Virginia’s frog and toad community reflects the state’s remarkable range of elevation and habitat, from river-bottom wetlands to high mountain vernal pools. West Virginia is home to 15 species of frogs and toads, and each one plays a distinct role in controlling insect populations while serving as food for birds, snakes, and mammals throughout the food web. Learning to recognize even a handful of calls, whether it’s the sleigh-bell chorus of the spring peeper or the banjo-plunk of the green frog, turns any evening walk near water into a small field study.
For readers interested in comparing West Virginia’s amphibian diversity to neighboring regions, exploring the broader picture of frog species found around the world offers useful context for how this small mountain state fits into a much larger picture of amphibian biodiversity.
