Rare
Under 5% of wildlife watchers report an Estheria cristata sighting in London on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 1059th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Estheria cristata in London on a given day, so our monthly data shows no clear season.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Estheria cristata sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Tachinidae

GBIF citizen-science records
It is estimated from how often the Estheria cristata is recorded against all the insects logged in London (11 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.
