Rare
Under 5% of wildlife watchers report an Oriental Mayfly sighting in Osaka on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 304th most-seen of the 352 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report an Oriental Mayfly in Osaka on a given day, against under 5% in June to March, the lowest months.
3rd of 3
Of the 3 cities where we can rate Oriental Mayfly sightings, Osaka ranks 3rd at under 5%. The best odds are in Daejeon (South Korea, about 20%) and Seoul (South Korea, about 10%).
GBIF citizen-science records
It is estimated from how often the Oriental Mayfly is recorded against all the insects logged in Osaka (5 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.
