Rare
Under 5% of wildlife watchers report a Chorodna strixaria sighting in Hong Kong on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1005th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chorodna strixaria in Hong Kong on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Chorodna strixaria sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Chorodna strixaria sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Geometridae
The closest relatives of the Chorodna strixaria 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 Chorodna strixaria is recorded against all the insects logged in Hong Kong (5 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.
