Rare
Under 5% of wildlife watchers report a Diduga flavicostata sighting in Hong Kong on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 583rd 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.
July and September
In those months about 10% of wildlife watchers report a Diduga flavicostata in Hong Kong on a given day, against under 5% in August and October–June, the lowest months. Those are among Hong Kong's wettest months, with about 170 mm of rain a month against 25 mm in December.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Diduga flavicostata 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 Diduga flavicostata sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Diduga flavicostata 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 Diduga flavicostata is recorded against all the insects logged in Hong Kong (14 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.
