Gadirtha impingens
In 3 days ~30% in a week ~50%
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 →

With luck
About 10% of wildlife watchers report a Gadirtha impingens sighting in Daintree National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 339th most-seen of the 856 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
January and March–April
In those months about 20% of wildlife watchers report a Gadirtha impingens in Daintree National Park on a given day, against under 5% in February, May and October–November, the lowest months. Those are among Daintree National Park's wettest months, with about 290 mm of rain a month against 50 mm in September.
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.
Only Daintree National Park, in our data
Daintree National Park is the only park on Wallace's Line with enough records to rate Gadirtha impingens sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Nolidae
The closest relatives of the Gadirtha impingens that you can see in Daintree National Park (family Nolidae, Tufted Moths) are Acatapaustus mesoleuca (about 10%), Aiteta iridias (about 10%) and Negeta contrariata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gadirtha impingens is recorded against all the insects logged in Daintree National Park (12 verified sightings from 2019 to 2026), 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.
