With luck
About 10% of wildlife watchers report an Oriental Mayfly sighting in Seoul on a given day, based on 43 verified sightings from GBIF citizen-science data. It is the 105th 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–June and August–September
In those months about 10% of wildlife watchers report an Oriental Mayfly in Seoul on a given day, against under 5% in July and October–March, the lowest months.
2nd of 3
Of the 3 cities where we can rate Oriental Mayfly sightings, Seoul ranks 2nd at about 10%. The best odds are in Daejeon (South Korea, about 20%).
GBIF citizen-science records
It is estimated from how often the Oriental Mayfly is recorded against all the insects logged in Seoul (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.
