Doleschallia bisaltide, the autumn leaf, is a nymphalid butterfly found in South Asia, Southeast Asia, and Australasia. In Australia it is also known as the leafwing. The larvae are black, with two rows of dorsal white spots. Head with a pair of branched spines; rest of the segments with a dorsal and a lateral row of blue branched spines on each side. They feed on Artocarpus, Pseuderanthemum, Calycanthus, Ruellia, Girardina, Strobilanthus and Graptophyllum. The pupae are yellowish with numerous black spots; constricted in the middle; head produced into two points. There are several subspecies under Doleschallia bisaltide:
Doleschallia bisaltide andamanensis Fruhstorfer, 1899 This subspecies closely resembles the Indian form, but differs in the oblique yellow band on the upperside of the forewing, which is broader and extends from the middle of the costal margin uninterruptedly to interspace 4, though it is preapically constricted. On the upperside of the hindwing there is an inner as well as an outer conspicuous subterminal narrow-black band. On the underside, this subspecies is as variable as the typical form, but the ground colour in many specimens (presumably... Wikipedia →

Possible
About 20% of wildlife watchers report an Autumn Leaf sighting in Singapore on a given day, based on 702 verified sightings from GBIF citizen-science data. It is the 49th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April–July and December–February
In those months about 20% of wildlife watchers report an Autumn Leaf in Singapore on a given day, against about 10% in March and August–November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Autumn Leaf sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
7th of 10
Of the 10 cities where we can rate Autumn Leaf sightings, Singapore ranks 7th at about 20%. The best odds are in Tasikmalaya (Indonesia, about 40%), Yogyakarta (Indonesia, about 30%) and Jakarta (Indonesia, about 30%).
Same family: Nymphalidae
The closest relatives of the Autumn Leaf that you can see in Singapore (family Nymphalidae, Brush-footed Butterflies) are Brown Pansy (about 40%), Plain Tiger Butterfly (about 30%) and Tawny Coster (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Autumn Leaf is recorded against all the insects logged in Singapore (702 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.
