Possible
About 20% of wildlife watchers report a Polytremis pellucida 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 16th most-seen of the 86 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Polytremis pellucida in Nikko National Park on a given day, against under 5% in March–May and October–November, the lowest months. That is one of Nikko National Park's wettest months, with about 230 mm of rain against 100 mm in November.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Polytremis pellucida 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 Polytremis pellucida sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Polytremis pellucida 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.
