Possible
About 20% of wildlife watchers report an Asian Comma sighting in Nanjing on a given day, based on 47 verified sightings from GBIF citizen-science data. It is the 23rd most-seen of the 272 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 80%, if each day is a fresh chance.
October
In that month about 40% of wildlife watchers report an Asian Comma in Nanjing on a given day, against under 5% in January and April, the lowest months. That is one of Nanjing's driest months, with about 55 mm of rain against 240 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Asian Comma sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
20th of 28
Of the 28 cities where we can rate Asian Comma sightings, Nanjing ranks 20th at about 20%. The best odds are in Changsha (China, about 30%), Gwangju (South Korea, about 30%) and Changzhou (China, about 30%).
Same family: Nymphalidae
The closest relatives of the Asian Comma that you can see in Nanjing (family Nymphalidae, Brush-footed Butterflies) are Spotted Leopard Butterfly (about 20%), Blue Admiral (about 20%) and Lesser Purple Emperor (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Asian Comma is recorded against all the insects logged in Nanjing (47 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.
