Rare
Under 5% of wildlife watchers report a Bush Clover sighting in Seoul on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 248th 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 to July
In those months about 10% of wildlife watchers report a Bush Clover in Seoul on a given day, against under 5% in August to April, the lowest months. Those are among Seoul's wettest months, with about 190 mm of rain a month against 20 mm in January.
Yes
Of the 2 cities where we can rate Bush Clover sightings, Seoul has the highest daily chance: under 5%. Next come Beijing (China, under 5%).
Same family: Lycaenidae
The closest relatives of the Bush Clover that you can see in Seoul (family Lycaenidae, Gossamer-winged Butterflies) are Pale Grass Blue (about 20%), Short-Tailed Blue (about 10%) and Large Copper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bush Clover 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.
