With luck
About 10% of wildlife watchers report a Cromna sinensis sighting in Hong Kong on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 362nd 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.
March to May
In those months about 10% of wildlife watchers report a Cromna sinensis in Hong Kong on a given day, against under 5% in June to February, the lowest months.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Cromna sinensis sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cromna sinensis is recorded against all the insects logged in Hong Kong (25 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.
