With luck
About 10% of wildlife watchers report a Garden Grass-Veneer sighting in Wadden Sea National Park on a given day, based on 97 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 40th most-seen of the 818 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.
July
In that month about 30% of wildlife watchers report a Garden Grass-Veneer in Wadden Sea National Park on a given day, against under 5% in September to May, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Garden Grass-Veneer sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.

GBIF citizen-science records
It is estimated from how often the Garden Grass-Veneer is recorded against all the insects logged in Wadden Sea National Park (97 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.
