Possible
About 20% of wildlife watchers report an Asian Comma sighting in Shanghai on a given day, based on 127 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 215 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
October and November
In those months about 40% of wildlife watchers report an Asian Comma in Shanghai on a given day, against about 10% in April–June and December–January, the lowest months.
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.
16th of 28
Of the 28 cities where we can rate Asian Comma sightings, Shanghai ranks 16th 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 Shanghai (family Nymphalidae, Brush-footed Butterflies) are Tropical Fritillary (about 30%), Lesser Purple Emperor (about 10%) and Red Ring Skirt (about 10%), 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 Shanghai (127 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.
