With luck
About 10% of wildlife watchers report a Tongeia filicaudis sighting in Beijing on a given day, based on 100 verified sightings from GBIF citizen-science data. It is the 15th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
August to October
In those months about 20% of wildlife watchers report a Tongeia filicaudis in Beijing on a given day, against under 5% in January to April, the lowest months. Those are among Beijing's wettest months, with about 70 mm of rain a month against almost none in January.
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.
3rd of 12
Of the 12 cities where we can rate Tongeia filicaudis sightings, Beijing ranks 3rd at about 10%. The best odds are in Zhuhai [Macau] (China, about 20%) and Suzhou (China, about 20%).
Same family: Lycaenidae
The closest relatives of the Tongeia filicaudis that you can see in Beijing (family Lycaenidae, Gossamer-winged Butterflies) are Short-Tailed Blue (about 10%), Common Flash (about 10%) 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 Beijing (100 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.
