The larvae are general feeders on a wide variety of ornamental plants and agricultural row crops. While much of their damage is done by the typical feeding behavior of “cut” worms, where young plants are cut off at the base to feed on the foliage, these larvae also climb vines and trees to feed on fruit, vegetables, leaves, and buds of many plants. A complete life cycle is completed in 35-62 days in warm climates where there may be 5 generations per year and continuous activity throughout the year. In colder climates the pupa overwinters in the soil.
Removal of plant debris on the soil will help to remove cover the larvae need during the day, exposing them to predators and parasites. Contact insecticides can be applied to plants that show feeding damage and a granular insecticide applied to the soil can intercept larvae that emerge to feed at night.
