With luck
About 10% of wildlife watchers report a Rema costimacula sighting in Hong Kong on a given day, based on 59 verified sightings from GBIF citizen-science data. It is the 182nd 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–September and November
In those months about 10% of wildlife watchers report a Rema costimacula in Hong Kong on a given day, against under 5% in October and December–January, the lowest months.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Rema costimacula sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Rema costimacula that you can see in Hong Kong (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Banyan Tussock Moth (about 20%), Orvasca subnotata (about 20%) and Zhejiang Tussock Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rema costimacula is recorded against all the insects logged in Hong Kong (59 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.
