Catopsilia scylla, the orange migrant or orange emigrant, is a species of butterfly that lives in South East Asia and Australasia. Its larvae feed predominantly on plants of the genera Cassia and Senna. Adults are approximately 60–65 millimetres (2.4–2.6 in) long. The males have white forewings edged in black, and cadmium-yellow hindwings, usually with black spots on the margins. Females are similar, but have an additional group of black spots on the forewing, which often merge to form a dark ring.
Catopsilia scylla has a wide distribution in South East Asia and Australasia. Its range stretches from Myanmar, Cambodia, Philippines, Thailand, and Vietnam, along the Malay Peninsula, across Java and Sumatra, and over northern Australia. It was recently discovered in Sri Lanka.
In Australia, C. scylla has been recorded on various species of Senna, including S. didymobotrya, S. leptoclada and S. surattensis. In Singapore, host plants include Senna obtusifolia, Cassia fistula, and especially Senna pallida.
The eggs are milky white and spindle shaped, and are usually laid singly on a leaf of the host plant. The eggs hatch after 1.5–2 days... Wikipedia →

With luck
About 10% of wildlife watchers report an Orange Migrant sighting in Singapore on a given day, based on 180 verified sightings from GBIF citizen-science data. It is the 152nd most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
Any time of year
In every month with enough records, about 10% of wildlife watchers report an Orange Migrant in Singapore on a given day, so our monthly data shows no clear season.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Orange Migrant sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Catopsilia
The closest relatives of the Orange Migrant that you can see in Singapore (genus Catopsilia, Emigrants) are Lemon Migrant (about 10%) and Mottled Emigrant (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Orange Migrant is recorded against all the insects logged in Singapore (180 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.
