Rare
Under 5% of wildlife watchers report a Western Courtier Butterfly sighting in Seoul on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 214th most-seen of the 525 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June–July and December
In those months about 10% of wildlife watchers report a Western Courtier Butterfly in Seoul on a given day, against under 5% in January–May and August–November, the lowest months. Those are among Seoul's wettest months, with about 170 mm of rain a month against 20 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Western Courtier Butterfly sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Seoul, in our data
Seoul is the only city on Wallace's Line with enough records to rate Western Courtier Butterfly sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Nymphalidae
The closest relatives of the Western Courtier Butterfly that you can see in Seoul (family Nymphalidae, Brush-footed Butterflies) are Asian Comma (about 20%), Lesser Purple Emperor (about 10%) and Pallas' Sailer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Western Courtier Butterfly is recorded against all the insects logged in Seoul (13 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.
