With luck
About 10% of wildlife watchers report an Asian Comma sighting in Osaka on a given day, based on 44 verified sightings from GBIF citizen-science data. It is the 63rd most-seen of the 352 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report an Asian Comma in Osaka on a given day, against under 5% in January and July–August, 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.
27th of 28
Of the 28 cities where we can rate Asian Comma sightings, Osaka ranks 27th at about 10%. 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 Osaka (family Nymphalidae, Brush-footed Butterflies) are Tropical Fritillary (about 30%), Dot-Dash Sailer (about 10%) 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 Osaka (44 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.
