With luck
About 10% of wildlife watchers report a Garden Grass-Veneer sighting in Bavarian Forest National Park on a given day, based on 41 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 108th most-seen of the 1115 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Garden Grass-Veneer is recorded against all the insects logged in Bavarian Forest National Park (41 verified sightings from 2019 to 2026), 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.
