Rare
Under 5% of wildlife watchers report a Marcius longirostris sighting in Hong Kong on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 613th 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.
May and June
In those months about 10% of wildlife watchers report a Marcius longirostris in Hong Kong on a given day, against under 5% in July to April, the lowest months. Those are among Hong Kong's wettest months, with about 250 mm of rain a month against 25 mm in December.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Marcius longirostris sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Marcius longirostris is recorded against all the insects logged in Hong Kong (13 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.
