When the wings are closed, only the cryptic underside markings are visible, which consists of irregular patterns and striations in many shades of biscuit, buff, browns, yellow, and black.

[2] When the wings are open, the forewing exhibits a black apex, an orange discal band and a deep blue base.

There are two white oculi, one along the margin of the apical black band, and the other bordering the orange and deep blue areas.

A very broad oblique discal orange band from costa to apices of interspaces 1 and 2, this orange band is sprinkled with bluish black scales; apical third of wing velvety purpurescent (purple) black; a hyaline (glass-like) transverse spot near middle of interspace 2, and a subtriangular similar small preapical spot.

Underside very closely resembles a dry leaf; ground colour very variable, but usually some shade of brown (rusty, greyish, and yellowish browns being the most common), always with scattered dark dots or little dark patches having the appearance of fungus-like or lichenous growths so common on dead leaves in the tropics.

When the insect closes its wings over its back the likeness to a dead leaf is most striking, and is heightened by a straight transverse, narrow, dark band running from the apex of the forewing to the tornus of the hindwing, often with oblique narrower similar bands or lines given off from it, all simulating very closely the midrib and lateral veins of a leaf.

The orange oakleaf is found in India, Nepal, Bhutan, Bangladesh, and Myanmar, down to Tenasserim Hills.

[citation needed] In India, the butterfly flies in the Himalayas at low elevations, from Jammu and Kashmir, through Garhwal and Kumaon to West Bengal, Sikkim, Arunachal Pradesh, and other states of the northeast.

It is also found in central and peninsular India; it flies in Madhya Pradesh, Jharkhand, Chhattisgarh, Orissa and Andhra Pradesh; i.e. along the central Indian highlands to Pachmarhi and Amarkantak, the Western Ghats south to Bhimashankar, and in the Eastern Ghats north of the river Godavari.

[10] In a survey of Chongqing municipality, China carried out from 1998 to 2004, K. inachis was found to inhabit moist broad-leaf forests.

[11] The orange oakleaf is a powerful flier and usually flies in dense forests with good rainfall, amongst undergrowth and along stream beds.

[13] Investigations in an artificial climate chamber reveal that photoperiod and temperature play a role in the larval development and survival rate of the larvae of K. inachus.

The list of food plants include: In captive breeding in a net garden, females have been recorded to lay 245.7 eggs on average.
