Rare
Under 5% of wildlife watchers report a Borysthenes emarginatus sighting in Hong Kong on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 522nd 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.
May to July
In those months about 10% of wildlife watchers report a Borysthenes emarginatus in Hong Kong on a given day, against under 5% in August to April, the lowest months. Those are among Hong Kong's wettest months, with about 230 mm of rain a month against 25 mm in December.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Borysthenes emarginatus sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Hemiptera
The closest relatives of the Borysthenes emarginatus that you can see in Hong Kong (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Litchi Lantern Bug (about 20%), Lychee Stink Bug (about 20%) and Ricania guttata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Borysthenes emarginatus is recorded against all the insects logged in Hong Kong (17 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.
