Rare
Under 5% of wildlife watchers report a Scarce Chocolate-Tip sighting in Beijing on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 321st most-seen of the 401 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.
February and April
In those months about 10% of wildlife watchers report a Scarce Chocolate-Tip in Beijing on a given day, against under 5% in March and May–January, the lowest months. Those are among Beijing's driest months, with about 15 mm of rain a month against 150 mm in July.
Only Beijing, in our data
Beijing is the only city on Wallace's Line with enough records to rate Scarce Chocolate-Tip sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Scarce Chocolate-Tip is recorded against all the insects logged in Beijing (6 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.
