The bright-line brown-eye (Lacanobia oleracea) is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is a common species throughout Europe, but is also found in North Africa (Morocco and Algeria), temperate North Asia and Central Asia, Asia Minor, Syria, and Turkestan, northern India, China, Korea and Japan.
This species' common name is usefully descriptive: The forewings are dark reddish brown marked with a prominent light orange-brown stigma and a bright white subterminal line. The hindwings are grey, darker towards the termen. The wingspan is 34–44 mm. They are attracted to light, sugar and nectar-rich flowers.
[Wingspan 35 to 40 mm.] Forewing red brown clouded with darker; veins grey, whitish towards termen: reniform stigma orange in its upper part, dark fuscous below; orbicular round, white edged, sometimes very small; submarginal line finely white, toothed on veins 3 and 4 to termen; hindwing dull whitish, pale fuscous towards termen; the veins dark. The ground colour varies on one side to black brown, ab. obscura Spul, and on the other to rufous, ab. rufa... Wikipedia →

With luck
About 10% of wildlife watchers report a Bright-Line Brown-Eye sighting in London on a given day, based on 131 verified sightings from GBIF citizen-science data. It is the 262nd most-seen of the 1504 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.
May to September
In those months about 10% of wildlife watchers report a Bright-Line Brown-Eye in London on a given day, against under 5% in October to April, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Bright-Line Brown-Eye sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.

GBIF citizen-science records
It is estimated from how often the Bright-Line Brown-Eye is recorded against all the insects logged in London (131 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.
