Agriphila straminella is a species of moth of the family Crambidae. It was described by Michael Denis and Ignaz Schiffermüller in 1775 and is found in Europe and east across the Palearctic. The wingspan is 16–20 mm. The forewings are brown; a whitish median streak, ending in branches along veins 2-5, often separated by dark fuscous scales; dorsal 2/3 often wholly suffused with whitish-ochreous; a terminal series of black dots; cilia metallic. Hindwings are rather dark grey. The larva is pale pinkish-ochreous; spots brown; head and plate of 2 brown, darker-marked
The moth flies from June to September depending on the location. The larvae feed on various grasses, such as sheep's fescue (Festuca ovina), smooth meadowgrass (Poa pratensis), and wheat (Triticum aestivum). Wikipedia →

Rare
Under 5% of wildlife watchers report a Pearl Veneer sighting in Vienna on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 698th most-seen of the 1406 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.
July
In that month about 10% of wildlife watchers report a Pearl Veneer in Vienna on a given day, against under 5% in August to June, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Pearl 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.
21st of 22
Of the 22 cities where we can rate Pearl Veneer sightings, Vienna ranks 21st at under 5%. The best odds are in Liverpool (United Kingdom, about 30%), London (United Kingdom, about 10%) and Manchester (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Pearl Veneer is recorded against all the insects logged in Vienna (17 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.
