Rare
Under 5% of wildlife watchers report a Rhesala imparata sighting in Hong Kong on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 680th 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.
August to October
In those months about 10% of wildlife watchers report a Rhesala imparata in Hong Kong on a given day, against under 5% in November to July, the lowest months.
3rd of 3
Of the 3 cities where we can rate Rhesala imparata sightings, Hong Kong ranks 3rd at under 5%. The best odds are in Manila (Philippines, about 10%) and Singapore (Singapore, under 5%).
Same family: Erebidae
The closest relatives of the Rhesala imparata 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 Rhesala imparata is recorded against all the insects logged in Hong Kong (11 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.
