Ypthima baldus, the common five-ring, is a species of butterfly in the subfamily Satyrinae found in Asia. Male: Upperside brown, both forewing and hindwing with terminal margins much darker, and generally with more or less distinct subbasal and discal dark bands. Forewing with a large, slightly oblique, oval, bi-pupilled, yellow-ringed black, pre-apical ocellus. Hindwing with two postdiscal, round, uni-pupilled, similar but smaller ocelli, and very often one or two minute tornal ocelli also.
Underside similar to the underside in Y. philomela but the ochraceous-white ground colour paler, thin transverse brown striae coarser, the ocelli on the hindwing more distinctly arranged in an echelon, two tornal, two median, and two preapical, and on both forewing and hindwing more or less distinctly defined, subbasal, discal and subterminal brown transverse bands.
Female: Differs on the upperside in having the area surrounding or bordering the ocelli on both forewing and hindwing paler, closely irrorated (sprinkled) with brown striae, the discal transverse band generally clearly defined, and very often both the tornal, and at least one of the... Wikipedia →

With luck
About 10% of wildlife watchers report a Common Fivering sighting in Osaka on a given day, based on 43 verified sightings from GBIF citizen-science data. It is the 66th 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.
May and July
In those months about 20% of wildlife watchers report a Common Fivering in Osaka on a given day, against under 5% in March and December–January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Common Fivering sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 6
Of the 6 cities where we can rate Common Fivering sightings, Osaka ranks 4th at about 10%. The best odds are in Nagoya (Japan, about 20%), Sendai (Japan, about 20%) and Tokyo (Japan, about 10%).
Same family: Nymphalidae
The closest relatives of the Common Fivering that you can see in Osaka (family Nymphalidae, Brush-footed Butterflies) are Tropical Fritillary (about 30%), Dot-Dash Sailer (about 10%) and Asian Comma (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Fivering is recorded against all the insects logged in Osaka (43 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.
