With luck
About 10% of wildlife watchers report a Krananda latimarginaria sighting in Shanghai on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 62nd most-seen of the 215 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.
March–July and September–December
In those months about 10% of wildlife watchers report a Krananda latimarginaria in Shanghai on a given day, against under 5% in January–February and August, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Krananda latimarginaria sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 9 cities where we can rate Krananda latimarginaria sightings, Shanghai ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Suzhou (China, about 10%), Nagoya (Japan, about 10%) and Nanjing (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Krananda latimarginaria is recorded against all the insects logged in Shanghai (24 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.
