Eugnorisma depuncta, the plain clay, is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in 1761. It is found in most of Europe, west to England, north to Scotland and Fennoscandia, south to southern France, Italy, Sicily and Greece, east up to the Caucasus. It is not present in northern France, the Benelux or parts of western Germany.
The wingspan is 34–44 mm. Meyrick describes it thus: Antennae in male ciliated. Forewings light ochreous-brown; subbasal line anteriorly black-edged; first line black-edged posteriorly except towards dorsum; second partly dark-edged, on costa anteriorly blackish-edged; orbicular and reniform finely pale-edged, space between them and before orbicular browner; subterminal line anteriorly darker-edged. Hindwings fuscous, darker posteriorly. Larva dull brown; a dorsal series of diamonds darker-outlined; spiracular sufFusedly darker, spiracles white, dark-edged; subspiracular ochreous-whitish; head light brown, darker-marked.
Adults are on wing from July to September depending on the location. The larvae feed on Pulmonaria mollis, Lamium, Vaccinium myrtillus and Urtica dioica. Wikipedia →

With luck
About 10% of wildlife watchers report a Plain Clay sighting in Cairngorms National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 114th most-seen of the 300 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Plain Clay in Cairngorms National Park on a given day, against under 5% in September to June, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Plain Clay sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Cairngorms National Park, in our data
Cairngorms National Park is the only park on Wallace's Line with enough records to rate Plain Clay sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Plain Clay is recorded against all the insects logged in Cairngorms National Park (27 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.
