In 3 days ~10% in a week ~20%
Nycteola asiatica, the eastern nycteoline, is a moth of the family Nolidae. The species was first described by Leonid Konstantinovich Krulikovsky in 1904. It is found in most of Europe and east across the Palearctic to Japan.
The wingspan is 22–25 mm. It closely resembles Nycteola revayana and is separable only by genitalic characters. The moth flies in two generations from mid-June to September and from March to April depending on the location.
The larvae feed on Salix and Populus species. Wikipedia →

Rare
Under 5% of wildlife watchers report an Eastern Nycteoline sighting in Beijing on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 321st most-seen of the 401 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 to August
In those months about 10% of wildlife watchers report an Eastern Nycteoline in Beijing on a given day, against under 5% in September to May, the lowest months. Those are among Beijing's wettest months, with about 110 mm of rain a month against almost none in January.
Only Beijing, in our data
Beijing is the only city on Wallace's Line with enough records to rate Eastern Nycteoline sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Eastern Nycteoline is recorded against all the insects logged in Beijing (6 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.
