The markings are very consistent & practically infalliable.



A recent observation is that of Neocheritra amrita, not Manto hypoleuca.Correction : Correct as Manto hypoleuca.

A 2nd observation appears to be the same individual, but the upperside pic 2 is correctly Manto hypoleuca. Correction :Male Manto hypoleuca.

TL Seow: Cheers
Revision: The male Manto hypoleuca have less distinct streaks in HW space 4 , but is more distinguisable by its almost wholly orange HW.
