Promalactis suzukiella, Suzuki's promalactis moth, is a moth of the family Oecophoridae. It is native to Korea, Japan and Taiwan, but is an introduced species in the United States. It was originally recorded from the mid-Atlantic states in the early 2000s and by 2020 had expanded its range to encompass Texas and most of the states east of the Mississippi, with the exception of Florida, northern New England and Michigan.
The length of the forewing is 4.5–7 mm. Adults are on wing from March to late September, indicating at least two and possibly more generations per year. The larvae feed under the bark of rotting logs of Prunus virginiana, Quercus species and Prunus persica. Wikipedia →

Rare
Under 5% of wildlife watchers report a Suzuki's Promalactis Moth sighting in Seoul on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 319th 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 20%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Suzuki's Promalactis Moth in Seoul on a given day, against under 5% in August to May, the lowest months. Those are among Seoul's wettest months, with about 240 mm of rain a month against 20 mm in January.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Suzuki's Promalactis Moth sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
5th of 7
Of the 7 cities where we can rate Suzuki's Promalactis Moth sightings, Seoul ranks 5th at under 5%. The best odds are in Baltimore (United States, about 10%), Boston (United States, about 10%) and Washington (United States, about 10%).
Same order: Lepidoptera
The closest relatives of the Suzuki's Promalactis Moth that you can see in Seoul (order Lepidoptera, Butterflies and Moths) are Asian Comma (about 20%), Pale Grass Blue (about 20%) and Small White (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Suzuki's Promalactis Moth is recorded against all the insects logged in Seoul (8 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.
