With luck
About 10% of wildlife watchers report a Tongeia filicaudis sighting in Nanjing on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 93rd 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 Tongeia filicaudis in Nanjing on a given day, against under 5% in May and November–March, the lowest months. That is one of Nanjing's wettest months, with about 160 mm of rain against 40 mm in December.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Tongeia filicaudis sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 12
Of the 12 cities where we can rate Tongeia filicaudis sightings, Nanjing ranks 7th at about 10%. The best odds are in Zhuhai [Macau] (China, about 20%), Suzhou (China, about 20%) and Beijing (China, about 10%).
Same family: Lycaenidae
The closest relatives of the Tongeia filicaudis that you can see in Nanjing (family Lycaenidae, Gossamer-winged Butterflies) are Pale Grass Blue (about 20%), Angled Sunbeam (about 20%) and Holly Blue (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tongeia filicaudis 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.
