Rare
Under 5% of wildlife watchers report an Eristalis cerealis sighting in Beijing on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 177th 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.
October and November
In those months about 10% of wildlife watchers report an Eristalis cerealis in Beijing on a given day, against under 5% in December to September, the lowest months. Those are among Beijing's driest months, with about 20 mm of rain a month against 150 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Eristalis cerealis sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 9
Of the 9 cities where we can rate Eristalis cerealis sightings, Beijing ranks 7th at under 5%. The best odds are in Kathmandu (Nepal, about 20%), Kunming (China, about 20%) and Wuhan (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Eristalis cerealis is recorded against all the insects logged in Beijing (14 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.
