Possible
About 20% of wildlife watchers report a Straight-Banded Treebrown sighting in Kathmandu on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 71 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.
May to July
In those months about 30% of wildlife watchers report a Straight-Banded Treebrown in Kathmandu on a given day, against under 5% in August–October and December–February, the lowest months. Those are among Kathmandu's wettest months, with about 180 mm of rain a month against almost none in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Straight-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 Kathmandu, in our data
Kathmandu is the only city on Wallace's Line with enough records to rate Straight-Banded Treebrown sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Straight-Banded Treebrown is recorded against all the insects logged in Kathmandu (11 verified sightings), 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.
