Rare
Under 5% of wildlife watchers report a Giant Grass-Veneer sighting in Wadden Sea National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 422nd most-seen of the 818 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Giant Grass-Veneer in Wadden Sea National Park on a given day, against under 5% in September to May, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Giant Grass-Veneer sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Wadden Sea National Park, in our data
Wadden Sea National Park is the only park on Wallace's Line with enough records to rate Giant Grass-Veneer sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Giant Grass-Veneer that you can see in Wadden Sea National Park (family Crambidae, Crambid Snout Moths) are Garden Grass-Veneer (about 10%), Barred Grass-Veneer (about 10%) and Pearl Veneer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Giant Grass-Veneer is recorded against all the insects logged in Wadden Sea National Park (10 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.
