Rare
Under 5% of wildlife watchers report an Orthetrum lineostigma sighting in Beijing on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 288th 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.
July and August
In those months about 10% of wildlife watchers report an Orthetrum lineostigma in Beijing on a given day, against under 5% in September to June, the lowest months. Those are among Beijing's wettest months, with about 130 mm of rain a month against almost none in January.
Among the best
Of the 2 cities where we can rate Orthetrum lineostigma sightings, Beijing ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Seoul (South Korea, under 5%).
GBIF citizen-science records
It is estimated from how often the Orthetrum lineostigma 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.
