With luck
About 10% of wildlife watchers report a Marbled Green sighting in Copenhagen on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 160th most-seen of the 476 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.
July to September
In those months about 10% of wildlife watchers report a Marbled Green in Copenhagen on a given day, against under 5% in October to June, the lowest months.

GBIF citizen-science records
It is estimated from how often the Marbled Green is recorded against all the insects logged in Copenhagen (20 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.
