With luck
About 10% of wildlife watchers report a Banded Treebrown sighting in Guangzhou on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 132nd most-seen of the 482 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
February, April–July and October
In those months about 10% of wildlife watchers report a Banded Treebrown in Guangzhou on a given day, against under 5% in March, August–September and November–January, 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.
4th of 4
Of the 4 cities where we can rate Banded Treebrown sightings, Guangzhou ranks 4th at about 10%. The best odds are in Kathmandu (Nepal, about 20%), Hong Kong (China, about 10%) and Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Banded Treebrown is recorded against all the insects logged in Guangzhou (23 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.
