Bright Line Brown Eye

Lacanobia oleracea


In a Nutshell

  • Damage from feeding on leaves and/or fruits.
  • Caterpillars speckled white and black with yellow stripes on flanks.
  • Light-brown moths with a white zig-zagging line and two reddish mark on each wing.



Capsicum & Chili






Chewing damage is visible on young leaves, stems, flowers and fruits. Moths are light brown with a white zigzag line (W-like) and a characteristic kidney-like reddish mark on each wing. The females lays eggs in groups of about 150 units and place them on the leaves undersides of their host plants. The eggs are initially light green and later somewhat darker green to ash-grey. Caterpillars reach a size of up to 5 cm and their color ranges from green to dark brown, with white and black speckles and a yellow stripe on each flank.


Bright Line Brown Eye is found in a variety of habitats such as gardens, greenhouses, on farmland, along rivers or forest clearings. It prefers humid and nutrient-rich sites. The pupae hibernate in the soil. The adult moth normally emerges in may with slight variation in timing according to temperature. Bright Line Brown Eye is spread worldwide and causes immense damage in vegetable cultivation.

Biological Control

In some moth species, the introduction of Trichogramma parasitoid wasps reduces caterpillar populations. Use insecticides containing Spinosad or Bacillus Thuringiensis that do not persist in the environment.

Chemical Control

Always consider an integrated approach with preventive measures together with biological treatments if available.

Preventive Measures

Protect plants with a net.,Monitor your field and remove eggs, infected plant parts or caterpillars.,Monitor soil after harvest and remove remaining pupae.
