With luck
About 10% of wildlife watchers report a Golden Flangetail sighting in Nanjing on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 150th 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 40%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a Golden Flangetail in Nanjing on a given day, against under 5% in September to April, the lowest months. Those are among Nanjing's wettest months, with about 170 mm of rain a month against 40 mm in December.
Among the best
Of the 7 cities where we can rate Golden Flangetail sightings, Nanjing ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Nagoya (Japan, about 10%) and Beijing (China, about 10%).
Same family: Gomphidae
The closest relatives of the Golden Flangetail that you can see in Nanjing (family Gomphidae, Clubtails) are Common Flangetail (about 10%) and Trigomphus agricola (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Golden Flangetail is recorded against all the insects logged in Nanjing (10 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.
