Rare
Under 5% of wildlife watchers report a Bombylius callopterus sighting in Beijing on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 288th 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.
March and April
In those months about 10% of wildlife watchers report a Bombylius callopterus in Beijing on a given day, against under 5% in May to February, 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 Bombylius callopterus sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Diptera
The closest relatives of the Bombylius callopterus that you can see in Beijing (order Diptera, Flies) are Common Drone Fly (about 10%), Phytomia zonata (about 10%) and Marmalade Hover Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bombylius callopterus is recorded against all the insects logged in Beijing (8 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.
