Xylastodoris luteolus
Royal Palm Bug
Xylastodoris luteolus is a thaumastocorid true bug that feeds exclusively on royal palms (Roystonea regia). Adults are golden-yellow, darkening with age; nymphs are pale yellow to orange. The species completes development from egg to adult in approximately 30 days at 80°F, passing through five nymphal instars. Its feeding causes distinctive yellow spots on leaflets that expand into brown necrotic areas, resulting in premature leaf death. No natural enemies have been documented.
