Rare
Under 5% of wildlife watchers report an Epistrophella euchromus sighting in London on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 971st 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.
April
In that month about 10% of wildlife watchers report an Epistrophella euchromus in London on a given day, against under 5% in May to March, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Epistrophella euchromus sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Syrphidae

GBIF citizen-science records
It is estimated from how often the Epistrophella euchromus is recorded against all the insects logged in London (13 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.
