Possible
About 20% of wildlife watchers report an Alpine Black Swallowtail sighting in Nikko National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 53rd most-seen of the 86 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report an Alpine Black Swallowtail in Nikko National Park on a given day, against under 5% in February–May and September–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Alpine Black Swallowtail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Nikko National Park, in our data
Nikko National Park is the only park on Wallace's Line with enough records to rate Alpine Black Swallowtail sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Alpine Black Swallowtail is recorded against all the insects logged in Nikko National Park (5 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.
