With luck
About 10% of wildlife watchers report a Theretra japonica sighting in Seoul on a given day, based on 89 verified sightings from GBIF citizen-science data. It is the 37th most-seen of the 525 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July to September
In those months about 20% of wildlife watchers report a Theretra japonica in Seoul on a given day, against under 5% in November to April, the lowest months. Those are among Seoul's wettest months, with about 250 mm of rain a month against 20 mm in January.
Among the best
Of the 9 cities where we can rate Theretra japonica sightings, Seoul ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Nagoya (Japan, about 10%).
Same family: Sphingidae
The closest relatives of the Theretra japonica that you can see in Seoul (family Sphingidae, Sphinx Moths) are Clanis bilineata (about 10%), Convolvulus Hawkmoth (about 10%) and Elephant Hawkmoth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Theretra japonica is recorded against all the insects logged in Seoul (89 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.
