Graphium doson
In 3 days ~70% 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 →

Possible
About 30% of wildlife watchers report a Common Jay sighting in Mumbai on a given day, based on 289 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 362 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March–April and June
In those months about 40% of wildlife watchers report a Common Jay in Mumbai on a given day, against about 10% in October, the lowest month.
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.
10th of 41
Of the 41 cities where we can rate Common Jay sightings, Mumbai ranks 10th at about 30%. The best odds are in Solapur (India, about 50%), Durg (India, about 40%) and Vijayawada (India, about 40%).
Same genus: Graphium
The closest relatives of the Common Jay that you can see in Mumbai (genus Graphium, Swordtails, Jays, Bluebottles and allies) are Tailed Jay (about 40%) and Spot Swordtail (about 10%), 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 Mumbai (289 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.
