Rare
Under 5% of wildlife watchers report a Spotted Elm Aphid sighting in Beijing on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 222nd 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.
April and October–November
In those months about 10% of wildlife watchers report a Spotted Elm Aphid in Beijing on a given day, against under 5% in May–September and December–March, the lowest months. Those are among Beijing's driest months, with about 25 mm of rain a month against 150 mm in July.
Among the best
Of the 2 cities where we can rate Spotted Elm Aphid sightings, Beijing ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Madrid (Spain, under 5%).
GBIF citizen-science records
It is estimated from how often the Spotted Elm Aphid is recorded against all the insects logged in Beijing (10 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.
