Narrow distribution. Known only from the central Pacific. On coconuts, but also stilt roots of Pandanus. An important pest.
After the nuptial flight, the queen lays eggs, producing workers and a few solders. Once the colony is established, it begins hollowing out the centre of the palm; this makes it likely to snap off in the wind.
Characteristic grooves covered with frass and wood are made in the “bark” for reasons unknown.
Cultural control: dig out and burn palms as soon as net-like grooves are seen.
Chemical control: not appropriate for this pest; the chemicals might contaminate the fresh water lens.
