Ohio’s 15 species of frogs and toads at a glance

An article entitled, Ohio’s Frog and Toad Species, states that there are 15 species in our state. To help me to learn to identify these species, I wanted to see photos of all 15 on one page. I selected a representative photo for each species from Flickr.

Keep in mind that a single species may vary a lot in color. Below each photo, I note the range of colors that are possible for that species.

Toads

The “True” Toads

Eastern American Toad (Bufo americanus americanus)

The Eastern American toad does vary in color. It may be reddish, gray, or tan.

Fowler’s Toad (Bufo fowleri)

The Fowler’s toad may be brown, tan, gray, or light green. The dark spots on the back of the Fowler’s toad have three or more “warts” while the dark spots, if present on the American toad, have only one or two “warts.” Another distinction is that the bumps on the leg of the American Toad tend to be more pronounced than those of the Fowler’s toad.

The Spadefoot Toads

There are two yellow lines on the Eastern Spadefoot’s back. It is the only frog/toad on this page whose pupils are vertical.

Frogs

The American bullfrog’s back may be green or brown.

Northern Green Frog (Rana clamitans melanota)

The back of the Northern Green Frog may be green or brownish green. It may or may not have noticeable spots. When it doesn’t seem to have spots, you can still distinguish it from the American Bullfrog because the Northern Green Frog has a ridge going down each side of its back, while the American Bullfrog does not.

Pickerel Frog (Rana palustris)

The Pickerel Frog may be tan, light brown, or olive-green. Note that the spots between the folds on the frog’s back have a squarish quality.

Northern Leopard Frog (Rana pipiens pipiens)

The Northern Leopard Frog may be tan, light brown, or olive-green. Note that the spots have a light-colored rim.

Southern Leopard Frog (Rana sphenocephala utricularius)

The Southern Leopard Frog may be green or brown. Unlike the Northern Leopard Frog, the spots of the Southern Leopard Frog don’t have a light border.

Wood Frog (Rana sylvatica)

Frogs mating
Photographed by me at Dawes Arboretum; these frogs are both wood frogs,
so this gives you some idea of the variation in color that’s possible.

Wood frogs are typically dark brown or tan, but occasionally individuals have been discovered that are a reddish color, or even pink.

The Tree Frogs

Blanchard’s Cricket Frog (Acris crepitans blanchardi)

Cope’s gray tree frogs (Hyla chrysoscelis)

The Cope’s gray tree frog (above) and the Eastern gray tree frog (below) are supposed to look virtually identical, but they are very different genetically. You might be saying to yourself, “Hey, they don’t look so very identical to me.” But as mentioned at the top of this post, this is part of the normal variability in color that occurs in many of these species. Typically these two species are gray, but they can change to green.

Eastern Gray Treefrog (Hyla versicolor)

  1. RUTH HOPKINS says:

    I FOUND A TOAD RESEMBLING THE FOWLER OR EASTERN TOAD IN MY GARAGE AMOUNG SOME WET CARDBOARD BOXES ON THE FLOOR, BUT THE TOAD I FOUND HAD A DEFINITE BLUE COLOR MIXED IN WITH THE DARK BROWN OF IT’S BACK. ANY SUGGESTION AS TO THE IDENTITY? THANKS

    • Deb Platt says:

      Ruth, I don’t believe any of the toads in our state have a blue pigment. I am wondering if the blue color was transferred onto the toad from something it was crawling through. For instance, if you put down one of those plastic grocery bags on a wet counter, the pigment from the writing on the bag will transfer from the bag to the counter. So maybe there was some blue printing on the cardboard boxes, and the toad crawled through it. Or maybe there was some mold on the boxes (mold can have a bluish cast).

      If that’s not the case, I confess that you’ve totally stumped me.

      • Amy Miller says:

        we just found a frog exactly what ruth said but it was in our garden it was neon green with a bright blue streak down it back

        • Deb Platt says:

          I’m baffled by reports of frogs with blue streaks or blotches. I’ve wondered if this might be a lizard that has lost its tail (if a predator grabs the animal by the tail, the tail snaps off). There is a species of lizard that lives in the Cincinnati area that has blue markings. It’s known as a wall lizard. Jim McCormac has published a nice article about this lizard, including photos that show off its blue mark. You can see McCormac’s article here. Since its introduction to the area from Italy, the wall lizard population has grown to about a quarter million, and the lizard has spread into Indiana and Kentucky.

          I don’t have a photo of one myself, but here’s one that is licensed for free use that I found on Flickr.

          Wall Lizard (Podarcis muralis)

          Although the lizard in the above photo has a distinctly green back, the color varies. The photos of the one in the McCormac article show a wall lizard that isn’t green at all.

  3. Thanks for the comments distinguishing one from the other…very helpful!

  4. Kari Moon says:

    We just caught a released a HUGE frog in our pond. Obviously it’s so big that you assume it’s a bullfrog, but the bottom of the frog is throwing us off. it has a cool white and brown squiggly line action going on, very distinct. I’d love to e-mail someone a picture to show them this thing and just confirm it’s a bullfrog. The only other thing close that it looks like is the Northern Green Frog but it doesn’t have the ridges.

  5. I found a small frog with a green back and brownish tan belly. Could it be a western chorus frog? I live in northern madison, ohio if that’s any help.

    • Deb Platt says:

      Almost every frog and toad species shows a lot of variation in color. I am tempted to think that the frog that you saw may have been the Northern Green Frog. Did it have any ridges on its back? Is there a picture of it online anywhere that would be visible to me like Flickr? Instagram?

  6. Ryan says:

    My puppy was just found chewing on one of these amphibians. Are any in NE Ohio known to be toxic?

    • Deb Platt says:

      Ryan, all toads excrete an alkaloid poison (bufotoxin) from the glands behind their eyes when they are afraid. I don’t personally know whether the bufotoxin excreted by Ohio toads pose a danger to dogs; however, I did do a web search when I read your question. According to Dr. Bari Spielman at petplace.com, the two species of toad in the United States that pose the greatest danger to dogs are the Colorado River toad (found in the southwestern U.S.) and the Marine toad (also known as the Cane toad; found in southern Florida and Texas). Neither of these species are found in Ohio.

      According to Dr. Spielman, here are the symptoms exhibited by dogs that have been poisoned by toads:

      • Mouth irritation with foamy salivation
      • Depression
      • Weakness
      • Collapse
      • Difficulty breathing
      • Seizures
      • Fever
      • Vomiting
      • Diarrhea

      Since it’s been over 12 hours since you posted your question, I hope your dog is doing okay.

  7. Ali says:

    My grandmother lives in southern ohio and found a frog in her bathroom. She says it was bright lime green and had a stripe on it’s back. Possibly running diagonal. She may be confused on some of the details but any ideas on what type of frog it might have been?

  8. Daulton says:

    I am in central Ohio and I found a small frog that is just green and has small warts all on its back. The stomach is white. Any ideas on what this could be?

    • Deb Platt says:

      If it is warty, it is probably a toad. One way that you can confirm it’s a toad is to look for swellings on each side of the head behind the eyes. These swellings are called parotid glands. If an animal snatches up a toad with its mouth, the toad will emit toxins from these glands that may prompt the animal to spit it back out.

      We only have two species of toads in Ohio. Every single toad that I’ve seen while living in central Ohio has been an Eastern American toad, so I am assuming that they are much more common than the other species, the Fowler’s toad.

  9. Martha says:

    Need to ID a frog with a blue head, and the rest of him is bright green. He loves our swimming pool. We have grandkids coming to visit us soon, and wonder if he could be dangerous.

    • Deb Platt says:

      Sorry, I can’t help you out with this one. I don’t know of any frogs in Ohio that have blue heads. On the bright side, there are no toxic frogs in Ohio. However all toads can emit a toxin from glands right behind their eyes, but they do this when an animal has seized them to provoke the animal into spitting them back out.

  10. Bruce says:

    I’ve never seen such a small frog before:
    While walking my dog at Frohring Meadows park in western Geauga County, he went off into the meadow, where plants are nearly 4-feet high, and came out a few minutes later.
    He had a bright green spot on his head that I thought was a leaf but was a bright green frog — solid green, as bright as the leaf in the above photo over the head of the Blanchard’s Cricket frog.
    It leaped off his head as I was reaching to brush it off.
    It was not bigger than my thumbnail, and I’ve never seen such a small amphibious critter before.
    The park has numerous ponds and wet sites, and I hear spring peepers and tree frogs all the time.
    Any idea what that little frog could’ve been?

    • Deb Platt says:

      All of the frogs in the “tree frog” category are very, very small. Given the green color that you described, I am guessing that it was either an Eastern Gray Treefrog or a Cope’s gray tree frogs. Despite the word, gray, in the name both of these can be green.

      Although I don’t have a photo showing the scale on these two tree frogs, I do have one of a Northern Spring Creeper. He’s clinging to the surface of a maple leaf, so the leaf itself provides some scale showing how tiny he is. The gray tree frogs are also tiny like this. Click on the image to see a larger version of the photo.

  11. I’m responding to the lizard comment above. I have researched, kept, written about and photographed the local European Wall Lizards for many years. The local European Wall Lizard species Podarcis muralis does not have green on the top of its body. The species of wall lizard that does is Podarcis siculus and they do not live in the Cincinnati area. The two species are similar and both came from Italy. In the U.S., the Podarcis siculus wall lizard lives in southern California and New York city but are spreading. An article I wrote about the 3 European lizard species living in the United States can be seen here http://cavemanetris.hubpages.com/hub/Lizards-from-Italy-Living-in-the-USA. Photos are included in the article.
