Kallima inachus

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 →

Rare
Under 5% of wildlife watchers report an Orange Oakleaf sighting in Bangkok on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 147th most-seen of the 245 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and July
In those months about 10% of wildlife watchers report an Orange Oakleaf in Bangkok on a given day, against under 5% in May–June and August–March, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Orange Oakleaf sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Orange Oakleaf sightings, Bangkok ranks 3rd at under 5%. The best odds are in Dehradun (India, about 20%) and Taipei (Taiwan, about 10%).
GBIF citizen-science records
It is estimated from how often the Orange Oakleaf is recorded against all the insects logged in Bangkok (11 verified sightings), 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.
