Arhopala eumolphus, male, Cuc Phuong (May 2016)
Members of this genus are extremely challenging to identify from field shots alone - it's often necessary to collect specimens (at least to examine upperwings)

Monastyrskii & Devyatkin (2016) listed 53 Arhopala species recorded in Vietnam, the great majority from the South and Central regions. Only 9 are recorded in the North: A. centaurus nakula, A. dispar dispar, A. perimuta perimuta, A. elopura dama, A. bazalus teesta, A. eumolphus eumolphus, A. birmana birmana, A. paraganesa zephyretta and A. ammonides ammonides.
Distinguishing the Arhopala species is very difficult, and best achieved by reference to keys and genitalia illustrations.
Arhopala eumolphus is one of several species in which the males are metallic green above (and the only one among the 9 species listed above).
