With luck
About 10% of wildlife watchers report a Common Banded Demon sighting in Hong Kong on a given day, based on 75 verified sightings from GBIF citizen-science data. It is the 158th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Common Banded Demon in Hong Kong on a given day, against under 5% in April and December–January, the lowest months. That is one of Hong Kong's wettest months, with about 190 mm of rain against 25 mm in December.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Banded Demon sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Common Banded Demon sightings, Hong Kong ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Singapore (Singapore, about 10%) and Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Banded Demon is recorded against all the insects logged in Hong Kong (75 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.
