Possible
About 20% of wildlife watchers report an Asian Comma sighting in Nikko National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 53rd most-seen of the 86 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.
October
In that month about 50% of wildlife watchers report an Asian Comma in Nikko National Park on a given day, against under 5% in February–August and November–December, 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.
Only Nikko National Park, in our data
Nikko National Park is the only park on Wallace's Line with enough records to rate Asian Comma sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Nymphalidae
The closest relatives of the Asian Comma that you can see in Nikko National Park (family Nymphalidae, Brush-footed Butterflies) are Mourning Cloak (about 30%), Diana Treebrown (about 30%) and Tropical Fritillary (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 Nikko National Park (5 verified sightings from 2019 to 2026), 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.
