Rare
Under 5% of wildlife watchers report a Dot-Dash Sailer sighting in Seoul on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 268th 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.
May–June and September
In those months about 10% of wildlife watchers report a Dot-Dash Sailer in Seoul on a given day, against under 5% in July–August and October–April, the lowest months.
2nd of 3
Of the 3 cities where we can rate Dot-Dash Sailer sightings, Seoul ranks 2nd at under 5%. The best odds are in Osaka (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Dot-Dash Sailer is recorded against all the insects logged in Seoul (11 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.
