With luck
About 10% of wildlife watchers report a Krananda latimarginaria sighting in Nanjing on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 89th most-seen of the 272 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Krananda latimarginaria in Nanjing on a given day, against under 5% in July and December–February, the lowest months. That is one of Nanjing's wettest months, with about 160 mm of rain against 40 mm in December.
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, Nanjing ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Suzhou (China, about 10%) and Nagoya (Japan, about 10%).
Same family: Geometridae
The closest relatives of the Krananda latimarginaria that you can see in Nanjing (family Geometridae, Geometer Moths) are Ninodes splendens (about 10%) and Sebastosema bubonaria (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Krananda latimarginaria is recorded against all the insects logged in Nanjing (15 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.
