Graphium evemon
In 3 days ~40% in a week ~70%
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 →

GBIF citizen-science records
It is estimated from how often the Lesser Jay is recorded against all the insects logged in Gunung Leuser National Park (9 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.
