Rare
Under 5% of wildlife watchers report a Coarse-Punctured Nomia sighting in Beijing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 349th 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.
June
In that month about 10% of wildlife watchers report a Coarse-Punctured Nomia in Beijing on a given day, against under 5% in July to May, the lowest months. That is one of Beijing's wettest months, with about 85 mm of rain against almost none in January.
Among the best
Of the 2 cities where we can rate Coarse-Punctured Nomia sightings, Beijing ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Taipei (Taiwan, under 5%).
GBIF citizen-science records
It is estimated from how often the Coarse-Punctured Nomia is recorded against all the insects logged in Beijing (5 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.
