Rare
Under 5% of wildlife watchers report a Poplar Pithead sighting in London on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 895th most-seen of the 1504 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.
May
In that month about 10% of wildlife watchers report a Poplar Pithead in London on a given day, against under 5% in June to April, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Poplar Pithead sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Syrphidae
The closest relatives of the Poplar Pithead that you can see in London (family Syrphidae, Hover Flies) are Yellow-Haired Sun Fly (about 40%), Marmalade Hover Fly (about 30%) and Hornet Mimic Hover Fly (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Poplar Pithead is recorded against all the insects logged in London (15 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.
