The back is yellow, light brown or reddish brown with 17 broad dark crossbands on body and tail, the belly is yellowish green, and juveniles are green with black bands (Wikipedia, general species account).

It lives in mid-hill rainforest and is arboreal and diurnal. A female may produce two to three eggs at a time. Nationally Critically Endangered (Sri Lanka National Red List 2012).
