Diet
Phloem-feeding; sucks sap from palm tissues. Specific feeding on Phoenix dactylifera and other Phoenix documented.
Host Associations
- Phoenix dactylifera - primary date palm
- Phoenix - -level other palm in occasionally infested

More Details
Monotypy
is exceptionally rare among insect in containing only one (Phoenicococcus) and one (P. marlatti). This extreme specialization on Phoenix palms may explain the lack of diversification.
