Rare
Under 5% of wildlife watchers report a Pselliophora bifascipennis sighting in Beijing on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 260th 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.
August and November
In those months about 10% of wildlife watchers report a Pselliophora bifascipennis in Beijing on a given day, against under 5% in September–October and December–July, the lowest months.

Of the 2 cities where we can rate Pselliophora bifascipennis sightings, Beijing ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Tokyo (Japan, under 5%).
Same order: Diptera
The closest relatives of the Pselliophora bifascipennis 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 Pselliophora bifascipennis 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.
