Smerinthus planus
In 3 days ~10% in a week ~30%
Smerinthus planus, the Oriental eyed hawkmoth, is a moth of the family Sphingidae. It was described by Francis Walker in 1856. It is found from northern Xinjiang across northern China, Mongolia and south-eastern Siberia to the Russian Far East and Japan, and then south through Korea and Taiwan to Hainan, Yunnan and eastern Tibet.
The wingspan is 70–100 mm. There are probably two generations per year in western China. Depending on latitude and weather, there are between one and four generations further east in China, with adults on wing between April and September.
The larvae feed on Populus and Salix species. Wikipedia →

Rare
Under 5% of wildlife watchers report an Oriental Eyed Hawkmoth sighting in Seoul on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 291st 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 and July–August
In those months about 10% of wildlife watchers report an Oriental Eyed Hawkmoth in Seoul on a given day, against under 5% in June and September–April, the lowest months. Those are among Seoul's wettest months, with about 240 mm of rain a month against 20 mm in January.
Yes
Of the 2 cities where we can rate Oriental Eyed Hawkmoth sightings, Seoul has the highest daily chance: under 5%. Next come Beijing (China, under 5%).
Same family: Sphingidae
The closest relatives of the Oriental Eyed Hawkmoth that you can see in Seoul (family Sphingidae, Sphinx Moths) are Theretra japonica (about 10%), Clanis bilineata (about 10%) and Convolvulus Hawkmoth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oriental Eyed Hawkmoth is recorded against all the insects logged in Seoul (9 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.
