Rare
Under 5% of wildlife watchers report a Herochroma cristata sighting in Hong Kong on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 731st 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.
March and April
In those months about 10% of wildlife watchers report a Herochroma cristata in Hong Kong on a given day, against under 5% in May 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 Herochroma cristata sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Geometridae
The closest relatives of the Herochroma cristata that you can see in Hong Kong (family Geometridae, Geometer Moths) are False Tiger Moth (about 30%), Milionia basalis (about 10%) and Orange Magpie Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Herochroma cristata is recorded against all the insects logged in Hong Kong (10 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.
