Narrow distribution. Southwest Pacific. On coconut, sago palm, Pandanus and some wild palms. Outbreaks occur, when it is an important pest.
Adults strip leaflets, leaving the midrib. Occasionally, defoliation occurs over several hundred hectares. Mature palms >25 m most affected.
Eggs in the crown, fall into the leaf base, leaf litter or weeds. Nymphs climb to the crown. Only males fly.
Natural enemies: chickens and myna birds take nymphs on the ground. There are parasitoid wasps that have been bred for biocontrol.
Cultural control: sticky bands around trunks (e.g., 'Tanglefoot'); control weeds to expose eggs to sun; intercrop with cocoa – nymphs climb the cocoa and starve; note, lighting fires to smoke the insects no longer acceptable as fires damages the palms.
