Rare
Under 5% of wildlife watchers report a Plain Grey Hawkmoth sighting in Seoul on a given day, based on 14 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.
June to September
In those months about 10% of wildlife watchers report a Plain Grey Hawkmoth in Seoul on a given day, against under 5% in October to May, the lowest months. Those are among Seoul's wettest months, with about 220 mm of rain a month against 20 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Plain Grey Hawkmoth sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
17th of 18
Of the 18 cities where we can rate Plain Grey Hawkmoth sightings, Seoul ranks 17th at under 5%. The best odds are in Xiuying District (China, about 20%), Nagoya (Japan, about 20%) and Shanghai (China, about 10%).
Same family: Sphingidae
The closest relatives of the Plain Grey 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 Plain Grey Hawkmoth is recorded against all the insects logged in Seoul (14 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.
