Rare
Under 5% of wildlife watchers report a Polymerus cognatus sighting in Beijing on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 184th 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.
June to August
In those months about 10% of wildlife watchers report a Polymerus cognatus in Beijing on a given day, against under 5% in September to May, the lowest months. Those are among Beijing's wettest months, with about 110 mm of rain a month against almost none in January.
Yes
Of the 2 cities where we can rate Polymerus cognatus sightings, Beijing has the highest daily chance: under 5%. Next come Seoul (South Korea, under 5%).
Same family: Miridae
The closest relatives of the Polymerus cognatus that you can see in Beijing (family Miridae, Plant Bugs) are Adelphocoris fasciaticollis (about 10%) and Eurystylus coelestialium (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Polymerus cognatus is recorded against all the insects logged in Beijing (13 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.
