With luck
About 10% of wildlife watchers report a Semiothisa cinerearia sighting in Beijing on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April to September
In those months about 10% of wildlife watchers report a Semiothisa cinerearia in Beijing on a given day, against under 5% in October to March, the lowest months. Those are among Beijing's wettest months, with about 80 mm of rain a month against almost none in January.
Yes
Of the 2 cities where we can rate Semiothisa cinerearia sightings, Beijing has the highest daily chance: about 10%. Next come Seoul (South Korea, under 5%).
GBIF citizen-science records
It is estimated from how often the Semiothisa cinerearia is recorded against all the insects logged in Beijing (41 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.
