Known principally from Thailand, but probably ranges much more extensively into Cambodia, Burma, and Bangladesh. Inhabits wetland vegetation around ponds and riparian zones in lowland forest but also seen up to 1000 m asl (Taksintum et al. 2012).

Life History, Abundance, Activity, and Special Behaviors
Males call for females at night while perched on vegetation or leaves above the ground especially after rainfall. Egg-laying follows amplexus and is usually on a leaf or plant stem, occasionally a rock, overhanging water sources. Males leave females once egg-laying is complete (usually returning to courtship calling) and the female gathers the eggs together with her hind limbs. As a form of parental care, the female frog will attend to the eggs until they hatch when the tadpoles will drop into water or are washed off the leaf by torrential rain into streams and ponds (Taksintum et al. 2012).

Egg attendance by females serves to protect the eggs from predation as Taksintum et al observed females jumping on the backs of grasshoppers that would eat the eggs (Taksintum et al. 2012).

This species was featured as News of the Week 12 June 2023:

A study on Feihyla hansenae, a rhacophorid treefrog from Thailand with terrestrial eggs, shows that embryos are capable of hatching early to escape flooding, and that failure to hatch results in mortality. By incorporating natural and experimental data into Monte Carlo methods to simulate and compare survival probabilities with and without hatching plasticity, Poo et al. (2023) found an overall increase in submergence survival due to hatching plasticity. As intensity and consistency of rainfall become more unpredictable and more variable due to climate change, there is a clear need for more life history data to increase the accuracy of our predictions on how animals may respond. These results add to the growing body of literature surrounding climate-correlated effects on poorly-studied amphibian populations. (Written by Sinlan Poo)
