Graphium evemon
In 3 days ~20% in a week ~50%
Graphium evemon, the blue jay, lesser jay, or pale green triangle is a species of tropical butterfly found in India, Indonesia, and Malaysia. Very similar to Graphium eurypylus, but treated as a distinct species. The scent-glands of the male always forms a narrow stripe hidden in the fold, the upperside of the abdomen is also never dusted with white in large males, the last submarginal spot of the forewing above is absent or at most weakly indicated and the harpe of the male genitalia is always recognisable by the long and more basally placed ventral process; moreover, in Malayan specimens the red costal spot on the under surface of the hindwing is always absent. The female is similar to the male.
Karl Jordan in Seitz ( pages 97, 98) provides a description differentiating evemon from nearby taxa and delineates the then known subspecies. Wikipedia →

With luck
About 10% of wildlife watchers report a Lesser Jay sighting in Singapore on a given day, based on 188 verified sightings from GBIF citizen-science data. It is the 150th 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 a Lesser Jay in Singapore on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Lesser Jay sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 cities where we can rate Lesser Jay sightings, Singapore has the highest daily chance: about 10%. Next come Kuala Lumpur (Malaysia, about 10%).
Same genus: Graphium
The closest relatives of the Lesser Jay that you can see in Singapore (genus Graphium, Swordtails, Jays, Bluebottles and allies) are Common Bluebottle (about 20%), Tailed Jay (about 10%) and Five-Bar Swordtail (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lesser Jay is recorded against all the insects logged in Singapore (188 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.
