In 3 days ~40% in a week ~70%
Pachliopta jophon, the Ceylon rose or Sri Lankan rose, is a butterfly found in Sri Lanka that belongs to the swallowtail family. It was earlier classified as a subspecies of Pachliopta hector, the crimson rose. It is endemic to Sri Lanka, confined to the rain forests of the central hill country in the south-west.
The male upperside is black. The forewing has three or four broad white streaks in a cell and a variable number of similar somewhat broader streaks that are bifid along their apical half in the interspaces beyond; these streaks do not reach the terminal margin and become obsolete towards the costal margin of the wing. The hindwing is in the apical half of the cell and short apically truncate streaks in the interspaces beyond white; these broad streaks broad are divided only by the black veins, followed by a subterminal curved series of crimson lunules irrorated with black scales. The underside is similar, the markings more distinct and more sharply defined; the discal white streaks and the subterminal series of crimson spots are each seven in number. The antennae, head, thorax, and abdomen above up to the pre-anal segment are black; the head in... Wikipedia →

Possible
About 20% of wildlife watchers report a Ceylon Rose Swallowtail sighting in Sinharaja Forest Reserve on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 46th most-seen of the 117 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, June and September
In those months about 30% of wildlife watchers report a Ceylon Rose Swallowtail in Sinharaja Forest Reserve on a given day, against under 5% in May, October and December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Ceylon Rose Swallowtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Sinharaja Forest Reserve, in our data
Sinharaja Forest Reserve is the only park on Wallace's Line with enough records to rate Ceylon Rose Swallowtail sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Papilionidae
The closest relatives of the Ceylon Rose Swallowtail that you can see in Sinharaja Forest Reserve (family Papilionidae, Swallowtails and Parnassians) are Great Mormon Swallowtail (about 40%), Sri Lankan Birdwing (about 30%) and Red Helen Swallowtail (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ceylon Rose Swallowtail is recorded against all the insects logged in Sinharaja Forest Reserve (22 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.
