With luck
About 10% of wildlife watchers report a Lasius japonicus sighting in Seoul on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 84th 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.
March to September
In those months about 10% of wildlife watchers report a Lasius japonicus in Seoul on a given day, against under 5% in October to February, the lowest months.
Among the best
Of the 5 cities where we can rate Lasius japonicus sightings, Seoul ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Sapporo (Japan, about 10%) and Sendai (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Lasius japonicus is recorded against all the insects logged in Seoul (36 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.
