Wall's bronzeback, or the blue bronzeback, is a colubrid snake found in South-east Asia. It is mainly tree-dwelling and inhabits primary and mature secondary lowland rainforest at altitudes up to 1,000 m. Like other bronzebacks it is active by day, lives entirely in trees and lays eggs (Wikipedia, general species account).
In India it occurs in Assam, Arunachal Pradesh (Namdapha in Changlang district), the Andaman Islands and northern parts of West Bengal. The Reptile Database also lists Sikkim and Mizoram.
