Possible
About 20% of wildlife watchers report an Asian Comma sighting in Tokyo on a given day, based on 618 verified sightings from GBIF citizen-science data. It is the 28th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March and October–November
In those months about 30% of wildlife watchers report an Asian Comma in Tokyo on a given day, against under 5% in January, the lowest month.
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.
23rd of 28
Of the 28 cities where we can rate Asian Comma sightings, Tokyo ranks 23rd 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 Tokyo (family Nymphalidae, Brush-footed Butterflies) are Red Ring Skirt (about 20%), Tropical Fritillary (about 20%) and Common Fivering (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 Tokyo (618 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.
