In 3 days ~70% in a week ~90%
Papilio gigon is a butterfly of the family Papilionidae. It is confined to islands in eastern Indonesia (Sulawesi, Sula and Talaud), but common where found [1]. The wingspan is 120–130 mm.Sexes similar, the female paler than the male Much larger than P. demolion, the costal margin of the forewing as in many Celebes butterflies strongly curved, the cell correspondingly strongly widened; also the cell of the hindwing differently formed from that of demolion, the subcostal arising much further distally than in that species, the band of the hindwing placed basally to the subcostal, cell of the hindwing beneath margined with yellow at the apex; in the genitalia nearest to P. liomedon. The young larva olive-green, prothorax and anal segment each with a pair of long tubercles, above the legs from the head to the anus a white stripe at each side, in the middle of the body a broad, dentate, white transverse band, which is joined to the lateral stripes. The full-grown larva blue-green, on the 3. segment a black transverse band, at the hindmargin of the 4. segment a transverse band which is light brown above, a third transverse band on the 7. and 8. segments, and a triangular lateral spot on the 9. segment; the first band in a larva observed by Kuhn on the island of Bangkai spectacle¬shaped, dark brown. Pupa light grass-green, with long, curved thoracic horn; a lateral stripe from the horn to the anal extremity brown, a central stripe of the same colour on the back
gigon Fldr. (= cresphontes Bdv. nec Cr.) (21 a). On the under surface of the hindwing the first black distal mark is about as broad at the costa as the yellowish white band, and the yellow margining of the apex of the cell is usually narrow and always produced in points at the veins. The whole of Celebes; whether the specimens from Siao and Bangkai agree with those from Celebes is not known to me [Jordan]. Common; its flight very rapid. — neriotes Rothsch., from Talaut and Sangir. The submarginal spots of the forewing beneath confluent, which sometimes also occurs in gigon in which case, however, the veins of this hand are more broadly dusted with white-yellow towards the base than in neriodes; the marginal spots of the hindwing beneath larger in both sexes than in gigon. — mangolinus Fruhst.

Possible
About 30% of wildlife watchers report a Celebes Banded Swallowtail sighting in Tangkoko Nature Reserve on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 38 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January
In that month about 60% of wildlife watchers report a Celebes Banded Swallowtail in Tangkoko Nature Reserve on a given day, against about 10% in March–April and November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Celebes Banded Swallowtail sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Tangkoko Nature Reserve, in our data
Tangkoko Nature Reserve is the only park on Wallace's Line with enough records to rate Celebes Banded Swallowtail sightings: about 30% of wildlife watchers there report one on a given day.
Same family: Papilionidae
The closest relatives of the Celebes Banded Swallowtail that you can see in Tangkoko Nature Reserve (family Papilionidae, Swallowtails and Parnassians) are Common Birdwing (about 50%), Milon's Bluebottle (about 20%) and Pachliopta polyphontes (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Celebes Banded Swallowtail is recorded against all the insects logged in Tangkoko Nature Reserve (20 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.
