• Worldwide distribution. On cabbage, cucumber, potato, daisy, legume plant families, and more. An important moth pest.
• Early larvae make 'windows' in leaves; later larvae make holes or defoliate plants.
• Eggs laid on underside of leaves; larvae blue-green, with white lines along body, up to 40 mm long. Move by looping. Pupae in silken cocoons in soil or on leaves. Adults, dark grey-brown, with silvery patches on forewings and two white spots, wingspan 30-40 mm, and bunched hairs like horns on head.
• Natural enemies: parasitoids give good control, and nuclear polyhedrosis virus effective.
• Cultural control: inspect nurseries and crops regularly; remove larvae by hand; use trap crops, e.g., mustards or Chinese cabbage (Bok Choy), but destroy trap crop before insects hatch.
• Chemical control: in household plots, use PDPs (chillies, neem, derris, or pyrethrum); in commercial plots, grow under nets; use Bt (Bacillus thuringiensis) sprays against caterpillars when young.

Green looper caterpillar, green garden looper. In Fiji, this has been called the green semi-looper. In this fact sheet it is called the 'tomato green looper'.

Chrysodeixis eriosoma; the identification of this moth in the Pacific may have been confused with a similar ('sister') moth, Chrysodeixis chalcites, which in Fiji is listed by Swaine (1971)¹ as Plusia chalcites. However, CABI (2014) lists no records of Chrysodeixis chalcites in the Pacific islands (it is in Australia and New Zealand), and quotes (Zang 1994): "Literature referring to C. chalcites (= chalcytes) in southern or eastern Asia or Oceania actually refers to C. eriosoma". However, the SPC surveys of Federated States of Micronesia and Palau record Chrysodeixis chalcites in Palau and the Northern Mariana Islands².According to the entry in Wikipedia, the two species cannot be separated morphologically, but they can be separated based on DNA, response to pheromones and distribution. These moths are member of the Noctuidae.
