Kallima inachus, the orange oakleaf, Indian oakleaf or dead leaf, is a nymphalid butterfly found in Tropical Asia from Pakistan to Japan. With wings closed, it closely resembles a dry leaf with dark veins and is a commonly cited example of camouflage.
The butterfly wings are shaped like a leaf when in the closed position. 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. The veins are darkened and resemble the veins of a leaf. The resemblance to a dried leaf, a masquerade, is extremely realistic and gives the genus its common names, the oakleaf or dead leaf.
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. The hindwing is more uniformly blue but diffused with brown patches along the termen.
Male and female butterflies are similar except that the female is generally larger and has the apex of the forewing protrude to form a longer point. Females also... Wikipedia →

With luck
About 10% of wildlife watchers report an Orange Oakleaf sighting in Kaeng Krachan National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 219th most-seen of the 296 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Orange Oakleaf is recorded against all the insects logged in Kaeng Krachan National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
