With luck
About 10% of wildlife watchers report a Hadennia mysalis sighting in Hong Kong on a given day, based on 53 verified sightings from GBIF citizen-science data. It is the 199th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February–April and June–December
In those months about 10% of wildlife watchers report a Hadennia mysalis in Hong Kong on a given day, against under 5% in January and May, the lowest months.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Hadennia mysalis sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Erebidae

GBIF citizen-science records
It is estimated from how often the Hadennia mysalis is recorded against all the insects logged in Hong Kong (53 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.
