Rare
Under 5% of wildlife watchers report a Rich Spiny Sugar Ant sighting in Hong Kong on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 488th 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.
February, April and November
In those months about 10% of wildlife watchers report a Rich Spiny Sugar Ant in Hong Kong on a given day, against under 5% in March, May–October and December–January, the lowest months. Those are among Hong Kong's driest months, with about 55 mm of rain a month against 280 mm in June.
10th of 12
Of the 12 cities where we can rate Rich Spiny Sugar Ant sightings, Hong Kong ranks 10th at under 5%. The best odds are in Tuen Mun (China, about 30%), Naha (Japan, about 10%) and Guangzhou (China, about 10%).
Same genus: Polyrhachis
The closest relatives of the Rich Spiny Sugar Ant that you can see in Hong Kong (genus Polyrhachis, Spiny Ants) are Polyrhachis vigilans (about 10%) and Polyrhachis illaudata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rich Spiny Sugar Ant is recorded against all the insects logged in Hong Kong (21 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.
