With luck
About 10% of wildlife watchers report a Shan Nawab sighting in Hong Kong on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 294th 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 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Shan Nawab in Hong Kong on a given day, against under 5% in September to June, the lowest months. Those are among Hong Kong's wettest months, with about 200 mm of rain a month against 25 mm in December.
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.
Yes
Of the 2 cities where we can rate Shan Nawab sightings, Hong Kong has the highest daily chance: about 10%. Next come Guangzhou (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Shan Nawab is recorded against all the insects logged in Hong Kong (35 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.
