Likely
About 40% of wildlife watchers report a Banded Treebrown sighting in Cuc Phuong National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 126 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
June
In that month about 60% of wildlife watchers report a Banded Treebrown in Cuc Phuong National Park on a given day, against under 5% in January and July–August, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Banded Treebrown sightings with a recorded time, and about 9 in 10 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 Banded Treebrown sightings: about 40% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Banded Treebrown is recorded against all the insects logged in Cuc Phuong National Park (19 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.
