Rare
Under 5% of wildlife watchers report an Eristalis cerealis sighting in Taipei on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 650th most-seen of the 765 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.
February
In that month about 10% of wildlife watchers report an Eristalis cerealis in Taipei on a given day, against under 5% in March to January, the lowest months. That is one of Taipei's driest months, with about 90 mm of rain against 270 mm in June.
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.
9th of 9
Of the 9 cities where we can rate Eristalis cerealis sightings, Taipei ranks 9th at under 5%. The best odds are in Kathmandu (Nepal, about 20%), Kunming (China, about 20%) and Wuhan (China, about 10%).
Same family: Syrphidae
The closest relatives of the Eristalis cerealis that you can see in Taipei (family Syrphidae, Hover Flies) are Marmalade Hover Fly (about 10%) and Phytomia zonata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eristalis cerealis is recorded against all the insects logged in Taipei (6 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.
