The sexes are alike. The hindwing tornus is developed into a long, curly tail. The upper side is bright orange with dull scales at the base. The forewing has a broad, black band commencing half way from the upper margin and goes across the apex up to the end of the outer margin. While the background colour of the underside varies, it is always paler than the upper side. It has a distal band of markings along both wings and some irregular patches located basally to the band. These markings are almost indistinct in some individuals. The tip of its tail is white in colour. The eye is prominent against its white body.
The Yamfly has a lovely appearance in flight due to its long tail streams. It flies delicately among scrubs, and along pathways in forests. It doesn’t fly too far even if it is disturbed and returns to the vicinity. It basks in the morning with partially opened wings, perching on the edge of a leaf while heading outwards. It feeds on flowers.
