Head is bronze above and yellowish below, with a black eyestripe between that connects to the black body line. Belly is pale yellowish.

Similar Species: Indo-Chinese Sand Snake lacks the black line and has yellow lines positioned in the brown background such that the yellow and brown striping have roughly the same width.
Copperhead Racer lacks the yellow stripe and has dark lines radiating from its eye.

Habitat: Found in forests, scrubland, parks, and agriculture. Will sometimes be seen on the edge of small clearings or in other habitat transitions that get more sunlight. Is partially arboreal and often found in bushes or small trees.

Place in the ecosystem: Eats frogs and lizards. Is fed on by larger snakes and birds of prey.

Danger to humans: Will bite if threatened but is not dangerous to humans.

Interesting facts: The Painted Bronzeback is quick and flighty and will usually flee immediately when approached. If it is cornered and can no longer flee it will inflate its body, showing off the bluish skin between its scales.
