English name: Three-striped Grass Frog (aka “Long-toed Frog”)
Scientific name: Hylarana macrodactyla (formerly known as Rana macrodactyla)
Thai name: Kob Lang keet
Description: To 5cm long. A small, slender frog with smooth skin and three gold stripes on the back. Body is green or brown. Dark spots can be found between the stripes. Head is long and narrow. Legs are long and especially slender. Underside is white.
Tadpoles are small and brown.
Call: A light chirp.
Similar Species: Green Paddy Frog is very similar in appearance, but is larger, slightly bulkier, and lacks the stripe in the middle of the back.
Asian Grass Frog has ridges on the skin and lacks stripes on the sides.
Habitat: Found in lowland lakes, marshes, floodplains, rice paddies, and open grassy areas in forest. Appears to favor flooded fields and marshes with vegetation, rather than open water.
Place in the ecosystem: Eats insects and spiders. Eaten by birds, snakes, large lizards, and fish.
Danger to humans: No danger to humans.
Conservation status and threats: The IUCN Red List lists the Three-striped Grass Frog as “Least Concern” due to its ability to tolerate a range of habitats and its large populations. However, it appears to have a scattered distribution.
Interesting facts: The scattered distribution of the Three-striped Grass Frog may be due to more specific habitat requirements than is currently known. Further study is important so that vital habitat can be preserved from draining and development. I have yet to find this species in the vicinity of Bangkok, which may only be the result of having not yet checked the correct habitat.

This frog is in my Bangkok garden, My garden is cat proof but This guy got in, its not easy as there are house extensions on all sides from my neighbors.
I wld really like it if u wld send me an email. I wld really like to talk to u more about the three striped grass frog. I live in the United States in southeast Georgia. I live in the country deep in the woods on a dirt road with a lot of mud puddles. I absolutely love frogs and tend to move frogs from dangerous areas and take them home bc I have a frog pond. Last summer I found a tree frog that I had never seen before. It looks just like a regular green tree frog but it is grey and brown and looks more like a snakes skin. This summer I have come across a frog that looks exactly like the three striped grass frog. They are in the mud puddles on my road and I have recently found a few hanging out in my frog pond. I’ve been calling them pud muddles. When they sence danger they bury themselves in the mud and watch u. Or they hop away. Plz email me so that I can send u pics to see if u can confirm what this strange frog is. I’ve never seen one before this year.
Wow I never thought I would get a reply but I got one,
Frogs are fairly easy to identify if you know your area and know whats supposed to be there however surprises happen,
especially when frogs are capable to climb moving objects that are stationary like interprovincial trucks etc
Candy emailed me a picture of her “pud muddle” frog, and it appears to be a Southern Leopard Frog, Rana sphenocephala. The Georgia Museum of Natural History has a great site for native reptiles and amphibians in the area.
Are you still around ?
I just know as i looked now you replied.
Candy yes I am still around just email directly to supparod@hotmail.com no long delay then.
I got this guy in my garden, Three stripped grass frog. I have a closed garden as everyone in my street built extentions to their houses.(Bangkok) Making my garden green with mainly palms and a Cerbera odollam tree. I have a pond with two Koi carp. And some fish that were guppies and have reverted to their pheno type over 14 years. I find it interesting that I try to seal my garden from Snakes etc. And so far one baby Water monitor has made it, A beautiful golden tree snake got in and ate a painted frog it stayed two days and left. Also a small python made it in. I note frogs can climb and its fascinating to see what gets in. I have a safe haven for birds and thus my garden has an input from the bird bath where they drop all manner of spores that allow many shrubs to have grown that I never planted. One last point. I have never in 15 years seen the birds foul the bird bath. They are very clean animals when it comes to bathing. The dominant bird of the garden is the Oriental Robin magpie. And without a doubt they eat fish. Online it says they might. But I know they actually do. I also have generations of Green and red vented balbuls.That have nested over the years. My front garden and its nature is a different story.
That’s great, good to know they’re around! And thank you for sharing those other observations too.
I have just found one of this frog on a large water lectuce in my guppy pond after I spent a month and a half to clean all green hair algae and put more water plants in. I would be welcomed if it lays eggs here since my pond has been dominated by a group of toads for quite sometimes.
Hey there. Big rain tonight. One of these guys is in my living room. He jumped in my house to avoid the flooding. I’m going to look for him tomorrow and maybe make him a pet if he wants. He has a lot of personality. I lost him for a while and i saw the knitted blanket on my couch hopping around and then his head poked out. I’m in Bangkok off Sukhumvit 107.
Hello I have another frog in my garden I never know how they get in as all the houses around me have built extensions on their gardens.
It barks like a dog I think as yet I am not clear what it is but it is living in a hollowed out coconut. That was supposed to be a bird nesting location.
I have a bird bath and pond thats safe from cats etc and so my garden gets lots of nice flowers popping up and growing from all the bird droppings they leave behind,
There is one intruder I would like to kick as yet I dont know how a Finlayson squrriel that is eating all my shoots and doing a lot of damage. There are no other trees around I suspect its someones pet soon to be compost if I ever figure how to get it.
I will be next here on Saturday or Friday night as I dont take my computer to the north.
In Scotland I rarely see frogs. Especially that really elusive one
Nice to chat…!
That sounds like a Brown Treefrog (also known as Four-lined Treefrog). I would describe it more like a duck than a dog, but that’s pretty close and living in a hollowed-out coconut is very much like them.
