Hestina assimilis
In 3 days ~80% in a week >90%
Hestina assimilis, the red ring skirt, is a species of butterfly in the family Nymphalidae found in Asia. It is generally of large size, and is named for the row of red submarginal spots on the hindwing of summer-generation adults. The species is saprophagous, with adults feeding on tree sap, rotting fruit and dung rather than nectar.
The species is native to northern Vietnam, southern and eastern continental China, the Korean Peninsula and adjacent islands, and to the Amami Islands of Japan, where the endemic subspecies H. a. shirakii occurs. A separate population of the continental nominate subspecies became established in central Honshu in the late 1990s and is treated in Japan as an invasive alien species. Wikipedia →

Likely
About 40% of wildlife watchers report a Red Ring Skirt sighting in Changzhou on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 12 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March
In that month about 70% of wildlife watchers report a Red Ring Skirt in Changzhou on a given day, against under 5% in May, the lowest month. November and December have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Red Ring Skirt sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 21 cities where we can rate Red Ring Skirt sightings, Changzhou has the highest daily chance: about 40%. Next come Hefei (China, about 20%) and Xiamen City (China, about 20%).
Same family: Nymphalidae
The closest relatives of the Red Ring Skirt that you can see in Changzhou (family Nymphalidae, Brush-footed Butterflies) are Tropical Fritillary (about 40%), Asian Comma (about 30%) 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 Red Ring Skirt is recorded against all the insects logged in Changzhou (15 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.
