The bright-line brown-eye (Lacanobia oleracea) is a moth of the family Noctuidae.

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.

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.

[1] The larva is green or brown dotted with white with black and yellow spiracular lines down the side with darker edging.

It feeds on a wide range of plants[2] and is occasionally a pest of cultivated tomatoes.
