With luck
About 10% of wildlife watchers report a Garden Grass-Veneer sighting in Berlin on a given day, based on 48 verified sightings from GBIF citizen-science data. It is the 196th most-seen of the 1065 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Garden Grass-Veneer in Berlin on a given day, against under 5% in August to May, the lowest months.

GBIF citizen-science records
It is estimated from how often the Garden Grass-Veneer is recorded against all the insects logged in Berlin (48 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.
