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 →

Rare
Under 5% of wildlife watchers report a Waste Grass-Veneer sighting in Madrid on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 377th most-seen of the 457 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August and September
In those months about 10% of wildlife watchers report a Waste Grass-Veneer in Madrid on a given day, against under 5% in October to July, the lowest months. Those are among Madrid's driest months, with about 20 mm of rain a month against 65 mm in October.
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.
7th of 7
Of the 7 cities where we can rate Waste Grass-Veneer sightings, Madrid ranks 7th at under 5%. The best odds are in Kyiv (Ukraine, about 10%), Bucharest (Romania, about 10%) and Milan (Italy, under 5%).
Same family: Crambidae
The closest relatives of the Waste Grass-Veneer that you can see in Madrid (family Crambidae, Crambid Snout Moths) are Rush Veneer (about 20%), Wandering Sunset (about 10%) and Jasmine Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Waste Grass-Veneer is recorded against all the insects logged in Madrid (7 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.
