Rare
Under 5% of wildlife watchers report a Shan Nawab sighting in Guangzhou on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 355th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and August
In those months about 10% of wildlife watchers report a Shan Nawab in Guangzhou on a given day, against under 5% in June–July and September–April, the lowest months. Those are among Guangzhou's wettest months, with about 260 mm of rain a month against 30 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.
2nd of 2
Of the 2 cities where we can rate Shan Nawab sightings, Guangzhou ranks 2nd at under 5%. The best odds are in Hong Kong (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Shan Nawab is recorded against all the insects logged in Guangzhou (7 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.
