With luck
About 10% of wildlife watchers report a Regal Pond Cruiser sighting in Nanjing on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 123rd most-seen of the 272 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April to September
In those months about 10% of wildlife watchers report a Regal Pond Cruiser in Nanjing on a given day, against under 5% in October to March, the lowest months. Those are among Nanjing's wettest months, with about 140 mm of rain a month against 40 mm in December.
Among the best
Of the 7 cities where we can rate Regal Pond Cruiser sightings, Nanjing ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Beijing (China, about 10%).
Same order: Odonata

GBIF citizen-science records
It is estimated from how often the Regal Pond Cruiser is recorded against all the insects logged in Nanjing (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.
