I spotted these tiny frogs one wet morning on the leaves of the plant where I had released the green tree frog. I believe they are young frogs that just lost their tails as they were that tiny!
A few had a slightly different pattern and colour.
I thought that perhaps it was possible for these froglets to be the young of the Malabar Flying Frog I had released here. But there wasn't any water body nearby. Whatever they are, or wherever they came from, I was glad I could spot and photograph such tiny and cute frogs in front of my house.
