In 3 days ~10% in a week ~30%
Gadirtha impingens is a moth of the family Nolidae first described by Francis Walker in 1858. It is found from northern India and southern China to Queensland, the Bismarck Archipelago and the Solomon Islands, as well in Japan (Honshu, Shikoku, Kyushu, Tsushima). The habitat consists of lowland areas up to 2,600 meters, but it is most frequent at elevations ranging from 1,000 to 2,000 meters.
The larvae feed on Sapium and Stillingia species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Gadirtha impingens sighting in Osaka on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 246th most-seen of the 352 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.
March and August–November
In those months about 10% of wildlife watchers report a Gadirtha impingens in Osaka on a given day, against under 5% in April–July and December–February, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Gadirtha impingens sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 cities where we can rate Gadirtha impingens sightings, Osaka has the highest daily chance: under 5%. Next come Tokyo (Japan, under 5%).
GBIF citizen-science records
It is estimated from how often the Gadirtha impingens is recorded against all the insects logged in Osaka (7 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.
