In 3 days ~20% in a week ~50%
Coelophora saucia is a species of ladybird in the family Coccinellidae. Coelophora saucia is endemic to Asia and can be found in India, Japan and the Philippines. It has also been collected in the Indochinese peninsula. It was introduced to Taiwan in order to control aphids (Aphidoidea) which feed on the country's sugar cane crops.
It was first described as Lemnia saucia by French entomologist, Étienne Mulsant, in 1850 from the collections of Frederick William Hope and John O. Westwood in the British Museum of Natural History. Wikipedia →

With luck
About 10% of wildlife watchers report a Coelophora saucia sighting in Nanjing on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 101st 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 50%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Coelophora saucia in Nanjing on a given day, against under 5% in January–February, June and October–November, the lowest months. That is one of Nanjing's driest months, with about 40 mm of rain against 240 mm in July.
Among the best
Of the 4 cities where we can rate Coelophora saucia sightings, Nanjing ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Hangzhou (China, about 10%).
Same family: Coccinellidae
The closest relatives of the Coelophora saucia that you can see in Nanjing (family Coccinellidae, Lady Beetles) are Asian Lady Beetle (about 30%), Seven-Spotted Lady Beetle (about 10%) and Turtle Vein Lady Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Coelophora saucia is recorded against all the insects logged in Nanjing (14 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.
