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 →

It is the 174th most-seen of the 838 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.

GBIF citizen-science records
It is estimated from how often the Pearl Veneer is recorded against all the insects logged in Helsinki (35 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.
