Rare
Under 5% of wildlife watchers report a Pterostoma sinica 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.
June
In that month about 10% of wildlife watchers report a Pterostoma sinica in Beijing on a given day, against under 5% in July to May, the lowest months. That is one of Beijing's wettest months, with about 85 mm of rain against almost none in January.
Only Beijing, in our data
Beijing is the only city on Wallace's Line with enough records to rate Pterostoma sinica sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Pterostoma sinica 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.
