Rare
Under 5% of wildlife watchers report a Tongeia filicaudis sighting in Tokyo on a given day, based on 56 verified sightings from GBIF citizen-science data. It is the 232nd most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
September and October
In those months about 10% of wildlife watchers report a Tongeia filicaudis in Tokyo on a given day, against under 5% in November to August, the lowest months. Those are among Tokyo's wettest months, with about 230 mm of rain a month against 75 mm in February.
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.
10th of 12
Of the 12 cities where we can rate Tongeia filicaudis sightings, Tokyo ranks 10th at under 5%. 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 Tokyo (family Lycaenidae, Gossamer-winged Butterflies) are Pale Grass Blue (about 30%), Small Copper (about 20%) and Pea 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 Tokyo (56 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.
