The celeno subgroup is recognised by the unbroken straight FW postdiscal band. J. malaccanus have the three main HW bands complete. In J. celeno & pura they are incomplete.
J. celeno is relatively very common.
The male upperside is very pale whitish blue with a black border of the FW outer margin (termen).
The upperside HW margin is also darker as can be seen here.
J. pura is a brighter blue to the margin (ie without a black border), a definitive ID.
Recorded in the past, its existence now in Singapore remains unproven.
2 is Pelopidas mathias.
There is some grey shading on the underside.
The Conjoined Swift is deeper brown , the upperside spots very yellow, the 2 cellspots tend to be elongate. http://www.ifoundbutterflies.org/med...oman_ag110.jpg
