Rare
Under 5% of wildlife watchers report a Semiothisa cinerearia sighting in Seoul on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 226th 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.
April to July
In those months about 10% of wildlife watchers report a Semiothisa cinerearia in Seoul on a given day, against under 5% in August to March, the lowest months. Those are among Seoul's wettest months, with about 160 mm of rain a month against 20 mm in January.
2nd of 2
Of the 2 cities where we can rate Semiothisa cinerearia sightings, Seoul ranks 2nd at under 5%. The best odds are in Beijing (China, about 10%).
Same family: Geometridae
The closest relatives of the Semiothisa cinerearia that you can see in Seoul (family Geometridae, Geometer Moths) are Erannis golda (about 10%) and Biston panterinaria (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Semiothisa cinerearia is recorded against all the insects logged in Seoul (13 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.
