Rare
Under 5% of wildlife watchers report a Mesembrius peregrinus sighting in Beijing on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 162nd 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 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Mesembrius peregrinus in Beijing on a given day, against under 5% in October to June, the lowest months. Those are among Beijing's wettest months, with about 110 mm of rain a month against almost none in January.

GBIF citizen-science records
It is estimated from how often the Mesembrius peregrinus is recorded against all the insects logged in Beijing (17 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.
