Hindwing with two sub-basal ring-spots, two in the cell and two at the end, all very indistinct; a discal band, slightly inwardly curved, composed as in the forewing and an indistinct submarginal series of lunules, some small brown suffusion at the anal angle and the tail brown edged.

Upperside somewhat paler than in the male, the marginal bands a little broader, the underside similar.The subspecies of Loxura atymnus are:[1][2][3] Loxura atymnus uses Smilax zeylanica (Order: Smilacaceae) and Dioscorea pentaphylla (Order: Dioscoreaceae) as host plant.

Smilax zeylanica is preferred for Oviposition and eggs are laid singly at the base of young shoots.

The fourth instar stops feeding after four days and attaches itself with a silk girdle and builds the pupal case.

Loxura atymnus is famous for consuming nectar secreted from the extrafloral nectaries stimulated by the ants. Here they are on a Philippine orchid bud along with some yellow crazy ants .
