With luck
About 10% of wildlife watchers report a Mountainous Duskywing sighting in Seoul on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 116th most-seen of the 525 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Mountainous Duskywing in Seoul on a given day, against under 5% in June to March, the lowest months.
Yes
Of the 3 cities where we can rate Mountainous Duskywing sightings, Seoul has the highest daily chance: about 10%. Next come Nanjing (China, about 10%) and Tokyo (Japan, under 5%).
GBIF citizen-science records
It is estimated from how often the Mountainous Duskywing is recorded against all the insects logged in Seoul (32 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.
