Rare
Under 5% of wildlife watchers report a Eurasian Hemp Moth sighting in Seoul on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 214th 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–July and September
In those months about 10% of wildlife watchers report a Eurasian Hemp Moth in Seoul on a given day, against under 5% in August and October–April, the lowest months. Those are among Seoul's wettest months, with about 170 mm of rain a month against 20 mm in January.
Yes
Of the 3 cities where we can rate Eurasian Hemp Moth sightings, Seoul has the highest daily chance: under 5%. Next come Tokyo (Japan, under 5%) and Beijing (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Eurasian Hemp Moth is recorded against all the insects logged in Seoul (15 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.
