Rare
Under 5% of wildlife watchers report an Acheron trux sighting in Hong Kong on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 613th 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 20%, if each day is a fresh chance.
May–June and August
In those months about 10% of wildlife watchers report an Acheron trux in Hong Kong on a given day, against under 5% in July and September–April, the lowest months. Those are among Hong Kong's wettest months, with about 240 mm of rain a month against 25 mm in December.
3rd of 4
Of the 4 cities where we can rate Acheron trux sightings, Hong Kong ranks 3rd at under 5%. The best odds are in Tuen Mun (China, about 10%) and Guangzhou (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Acheron trux is recorded against all the insects logged in Hong Kong (13 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.
