Rare
Under 5% of wildlife watchers report a Blasticorhinus rivulosa sighting in Hong Kong on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 868th 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.
October
In that month about 10% of wildlife watchers report a Blasticorhinus rivulosa in Hong Kong on a given day, against under 5% in November to September, the lowest months. That is one of Hong Kong's driest months, with about 50 mm of rain against 280 mm in June.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Blasticorhinus rivulosa sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Blasticorhinus rivulosa 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 Blasticorhinus rivulosa is recorded against all the insects logged in Hong Kong (7 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.
