Possible
About 30% of wildlife watchers report an Asian Comma sighting in Changzhou on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 5th most-seen of the 12 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.
September and October
In those months about 60% of wildlife watchers report an Asian Comma in Changzhou on a given day, against under 5% in May to July, the lowest months. November and December have too few records to rate.
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.
Among the best
Of the 28 cities where we can rate Asian Comma sightings, Changzhou ranks 3rd at about 30%, level with the leaders once rounded. The best odds are in Changsha (China, about 30%) and Gwangju (South Korea, about 30%).
Same family: Nymphalidae
The closest relatives of the Asian Comma that you can see in Changzhou (family Nymphalidae, Brush-footed Butterflies) are Tropical Fritillary (about 40%), Red Ring Skirt (about 40%) and Five-Dot Sergeant (about 30%), 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 Changzhou (6 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.
