Dendrelaphis schokari, commonly Schokar's bronzeback (Sinhala: තරු/මූකලන් හාල්දන්ඩා, Tharu/Mookalan Haaldanda in Sinhala), is a species non–venomous arboreal snake found in Sri Lanka.[1]

Diurnal and though a tree snake it is observed of foraging on land as well in searching of its prey which consist of frogs, lizards, geckos, skinks, insects and also eggs of small birds.

It can be distinguished easily from other Dendrelaphis species by having a cream color spotted line on its olive green dorsal from neck to mid fore body along the spine.[1][2][3][4]
