With luck
About 10% of wildlife watchers report a Chinese Nawab sighting in Nanjing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 242nd most-seen of the 272 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April, June, August and October
In those months about 10% of wildlife watchers report a Chinese Nawab in Nanjing on a given day, against under 5% in May, July, September and November–March, the lowest months.
Among the best
Of the 2 cities where we can rate Chinese Nawab sightings, Nanjing ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Suzhou (China, about 10%).
Same family: Nymphalidae
The closest relatives of the Chinese Nawab that you can see in Nanjing (family Nymphalidae, Brush-footed Butterflies) are Spotted Leopard Butterfly (about 20%), Blue Admiral (about 20%) and Asian Comma (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chinese Nawab is recorded against all the insects logged in Nanjing (5 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.
