Four-lined Tree Frog
   

Large female and small male mating pair,  Singapore.


Lightly speckled, dull brown specimen, Southern Thailand.


Orange-brown, mottled specimen, Singapore.

A common yet charming species of disturbed forests, scrubland, parks & gardens. Its repetitive monosyllabic call is an instantly recognisable sound in much of rural Southeast Asia. Most commonly encountered a few feet from the ground clinging to small stems, it may also be found in puddles on wet ground.

 The tadpoles are dark, with a white spot on the snout.
 

Its colour varies from green-grey to a less common ruddy-brown; the four lines on its back may be absent in some populations. Its eggs are laid next to ponds in a foamy mass glued to overhanging vegetation. Once hatched, the young tadpoles fall into the water below to start a new life.

This species occurs throughout the Oriental and Sunda regions, however it is not found in Sulawesi or east of Java (i.e. east of the Wallace Line).
