The hindwing underside of P. confucius is very similar to P. trachala.
In trying to check for the variations in P. trachala, I came across one of Federick's shot taken in April at the Punggol Wasteland.
This had been posted as P. trachala in Federick's skipper thread.
Unfortunately I had thought it was correct at the time.
This is P. confucius dushta male.
The hindwing is rather like P. trachala.
On the forewing. spot 4 widely overlaps spot 3 below it, and spot 5 widely overlaps spot 6 above it. http://www.butterflycircle.com/forum...1&d=1332683464
