Possible
About 30% of wildlife watchers report a Clown Stink Bug sighting in Nikko National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th 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 90%, if each day is a fresh chance.
November
In that month about 50% of wildlife watchers report a Clown Stink Bug in Nikko National Park on a given day, against under 5% in March–April, July and September–October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Clown Stink Bug sightings with a recorded time, and about 8 in 10 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 Clown Stink Bug sightings: about 30% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Clown Stink Bug is recorded against all the insects logged in Nikko 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.
