In 3 days ~10% in a week ~20%
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 Tokyo on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 872nd most-seen of the 1013 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Gadirtha impingens in Tokyo on a given day, so our monthly data shows no clear season.
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.
Among the best
Of the 2 cities where we can rate Gadirtha impingens sightings, Tokyo ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Osaka (Japan, under 5%).
GBIF citizen-science records
It is estimated from how often the Gadirtha impingens is recorded against all the insects logged in Tokyo (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.
