Pediasia contaminella is a species of moth in the family Crambidae described by Jacob Hübner in 1796. It is found in almost all of Europe, Asia Minor, the Caucasus, Transcaucasia, Iraq, Iran, the Kopet Dagh and Minusinsk.
The wingspan is 17–19 mm. It differs from Pediasia aridella as follows : forewings without blackish submediaii streak from base, median line less oblique, with more strongly marked discal indentation, nearly parallel to second.
Adults are on wing in July and August. The larvae feed on Poa species (including Poa maritima and Poa borreri) and Festuca ovina. They live in a silken tube. Wikipedia →

With luck
About 10% of wildlife watchers report a Waste Grass-Veneer sighting in Wadden Sea National Park on a given day, based on 41 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 171st most-seen of the 818 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.
July
In that month about 20% of wildlife watchers report a Waste Grass-Veneer in Wadden Sea National Park on a given day, against under 5% in September to June, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Waste Grass-Veneer sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 2 parks where we can rate Waste Grass-Veneer sightings, Wadden Sea National Park has the highest daily chance: about 10%. Next come Cévennes National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Waste Grass-Veneer is recorded against all the insects logged in Wadden Sea 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.
