• Narrow distribution. In Hawaii and Oceania. On coconuts and other palms. Occasionally serious on mature palms and seedlings, but effect on yield unknown.
• Larvae do the damage, making a protective fine web and eating the leaf from the underside. More abundant during dry weather.
• Natural enemies: several parasitoid wasp introductions have been made; also ants eat the eggs and spiders eat the adults.
• Cultural control: no recommendations.
• Chemical control: on mature palms pesticides unlikely to be economic, and will delay control by natural enemies; on seedlings, use synthetic pyrethroids, but they will also kill natural enemies.
