Graphium doson, the common jay, is a black, tropical papilionid (swallowtail) butterfly with pale blue semi-transparent central wing bands that are formed by large spots. There is a marginal series of smaller spots. The underside of wings is brown with markings similar to upperside but whitish in colour. The sexes look alike. The species was first described by father and son entomologists Cajetan and Rudolf Felder.
It is widespread and common throughout Southeast Asia, including lower elevations in Sri Lanka and southern India, Eastern Ghats, Satpuras, Bengal, Assam and Bangladesh, and the Himalayan foothills. The species is however scarce in southern Honshū, Japan. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Common Jay is recorded against all the insects logged in Kinabatangan Wildlife Sanctuary (6 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.
