Rare
Under 5% of wildlife watchers report a Chinese Yellowface sighting in Hong Kong on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 429th most-seen of the 1125 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.
April and June–September
In those months about 10% of wildlife watchers report a Chinese Yellowface in Hong Kong on a given day, against under 5% in May and October–March, the lowest months. Those are among Hong Kong's wettest months, with about 190 mm of rain a month against 25 mm in December.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Chinese Yellowface sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Chinese Yellowface sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Odonata
The closest relatives of the Chinese Yellowface that you can see in Hong Kong (order Odonata, Dragonflies and Damselflies) are Blue Marsh Hawk (about 30%), Indigo Dropwing (about 20%) and Crimson-Tailed Marsh Hawk (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chinese Yellowface is recorded against all the insects logged in Hong Kong (22 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.
