This moth has the potential to be damaging to citrus and other fruits by feeding directly on developing fruit as well as on the stems, leading to premature drop of the fruit. The larvae will feed on a tremendous diversity of plants, including many native flowering plants, grapevines, apple, apricot, cherry, many landscape shrubs, most conifers, oaks, ferns, and a wide variety of roadside weeds. Over 200 diverse host plants are known. The female moth lays batches of around 200 eggs in masses on the food plants. Early instar larvae feed under a layer of silk and often skeletonize the leaves. Later instars create feeding chambers for themselves by rolling leaf edges over or attaching leaves together with silk. Development to the pupa stage takes about 1 month and there typically are 2 generations per year in hotter, drier regions but up to 5 generations per year in cooler areas where the adult moths may be active year round.
Control is often with the use of insecticides sprayed over the foliage shortly after bud break and when the first signs of the larval feeding occur. The presence of just a few larvae or adult moths may not warrant the use of any insecticides. Natural enemies include parasitic wasps and lacewing larvae, and these often maintain the moth populations at a tolerable level.
