Possible
About 20% of wildlife watchers report an Aglia japonica sighting in Nikko National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 86 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.
May and June
In those months about 40% of wildlife watchers report an Aglia japonica in Nikko National Park on a given day, against under 5% in March–April and August–November, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Aglia japonica sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Nikko National Park, in our data
Nikko National Park is the only park on Wallace's Line with enough records to rate Aglia japonica sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Saturniidae
The closest relatives of the Aglia japonica that you can see in Nikko National Park (family Saturniidae, Emperor and Giant Silk Moths) are Ōmizuao (about 20%), Japanese Silk Moth (about 20%) and Japanese Moon Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Aglia japonica is recorded against all the insects logged in Nikko National Park (9 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.
