In 3 days ~30% in a week ~60%
Graphium chironides, the veined jay, is a species of butterfly found in Assam and other parts of Northeast India and Southeast Asia. Closely resembles in colour and in the disposition of the markings Graphium eurypylus, races jason and axion more especially the latter, but on the upperside the anterior markings are all strongly tinged with yellow and the spots or patches that compose the discal band on both forewing and hindwing are well separated one from the other; on the hindwing, moreover, the apical spot of the subterminal series is invariably white, not pale green like the other spots of the series, and is very often elongate and diffuse. Underside: forewing very similar to that of axion. Hindwing: with the following silvery white markings: a moderately broad basal band reaches from costa across the wing and along the dorsum to the tornal angle, broad elongate streaks in the cell and in interspaces 2 and 3, a small spot at base of interspace 4, an inwardly conical larger elongate spot at base of 6, a very large quadrate spot in 7, and an elongate spot like that in 6 in interspace but outwardly not inwardly conical, interior to the two latter spots are two broad...

With luck
About 10% of wildlife watchers report a Veined Jay sighting in Nanjing on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 40th most-seen of the 272 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Veined Jay in Nanjing on a given day, against under 5% in May and November–March, the lowest months. That is one of Nanjing's wettest months, with about 240 mm of rain against 40 mm in December.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Veined 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.
2nd of 5
Of the 5 cities where we can rate Veined Jay sightings, Nanjing ranks 2nd at about 10%. The best odds are in Guiyang (China, about 30%).
GBIF citizen-science records
It is estimated from how often the Veined Jay is recorded against all the insects logged in Nanjing (28 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.
