Possible
About 20% of wildlife watchers report a Shan Nawab sighting in Cuc Phuong National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 82nd most-seen of the 126 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.
June
In that month about 70% of wildlife watchers report a Shan Nawab in Cuc Phuong National Park on a given day, against under 5% in July–August and October–May, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Shan Nawab sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Cuc Phuong National Park, in our data
Cuc Phuong National Park is the only park on Wallace's Line with enough records to rate Shan Nawab sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Shan Nawab is recorded against all the insects logged in Cuc Phuong National Park (11 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.
