Diurnal and non-venomous snake recorded from wet and intermediate zones of lowlands to mid hills. However there are references
of finding it from Mullaitivu, Vavuniya and Trincomalee of northern dry zone*. Arboreal and feeds on
frogs, geckos, skinks and agamid lizards. Sometimes descends to the ground and
it is said that when moving on the ground it has a habit of keeping its head
and part of fore body erect(Snakes of Sri Lanka A coloured atlas – Anslem de
silva & jayantha Jinasena - 2009). This picture of Boulenger’s bronze-back
devouring probably a Spotted tree frog was taken in a shrub jungle of Ambagaspitiya
of Gampaha district.
* Though Anslem de Silva (Snakes of Sri Lanka A coloured atlas –
Anslem de silva & jayantha Jinasena - 2009) has given Wall (1921) as the reference
for its distribution in Mulativu and Vavuniya there is not such a mentioning in
Frank Wall’s Snakes of Ceylon(1921) page 218 where distribution of Dendrelaphis
bifrenalis only includes Punagalla, Yatiyantota, Balangoda and Galle.
