About the Bright-Line Brown-Eye

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 →

GBIF citizen-science records

It is estimated from how often the Bright-Line Brown-Eye is recorded against all the insects logged in Vienna (30 verified sightings), calibrated against known sighting rates.
