With luck
About 10% of wildlife watchers report an Adrisa magna sighting in Beijing on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 143rd 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.
April, June and August
In those months about 10% of wildlife watchers report an Adrisa magna in Beijing on a given day, against under 5% in May, July and September–March, the lowest months. Those are among Beijing's wettest months, with about 70 mm of rain a month against almost none in January.
Among the best
Of the 5 cities where we can rate Adrisa magna sightings, Beijing ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Hangzhou (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Adrisa magna is recorded against all the insects logged in Beijing (20 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.
