In 3 days ~80% in a week >90%
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 →

Likely
About 40% of wildlife watchers report a Common Jay sighting in Vijayawada on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 9 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 70% of wildlife watchers report a Common Jay in Vijayawada on a given day, against under 5% in December, the lowest month. That is one of Vijayawada's wettest months, with about 170 mm of rain against 5 mm in January. February has too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common 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.
3rd of 41
Of the 41 cities where we can rate Common Jay sightings, Vijayawada ranks 3rd at about 40%. The best odds are in Solapur (India, about 50%) and Durg (India, about 40%).
Same order: Lepidoptera
The closest relatives of the Common Jay that you can see in Vijayawada (order Lepidoptera, Butterflies and Moths) are Hawaiian Beet Webworm Moth (about 60%), Common Crow (about 40%) and Mung Bean Moth (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Jay is recorded against all the insects logged in Vijayawada (9 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.
