With luck
About 10% of wildlife watchers report a Gymnocheta viridis sighting in London on a given day, based on 60 verified sightings from GBIF citizen-science data. It is the 425th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report a Gymnocheta viridis in London on a given day, against under 5% in May to February, the lowest months.
Only London, in our data

Same family: Tachinidae

GBIF citizen-science records
It is estimated from how often the Gymnocheta viridis is recorded against all the insects logged in London (60 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.
