The genus Polyura is represented in Vietnam by 10 species – athamas, arja, moori, jalysus, delphis, narcaea, eudamippus, nepenthes, dolon and shreiber (Monastyrskii & Devyatkin, 2016).
Polyura athamas are medium-sized, heavy-bodies butterflies with rapid, strong and sometimes erratic flights. It has a habit of perching high on a spot in a tree, and keeps returning to the same perch after making swift flights in the vicinity to chase intruders away. The adults have also been observed to puddle on wet ground, carrion, faeces and tree sap.
