Royal Palm Bug

Xylastodoris luteolus (Hemiptera: Thaumastocoridae)

A very small, specialized pest that feeds exclusively on royal palm. Adults reach only 2.5mm in length and cause scattered yellow spots on leaf surfaces. While rarely fatal to palms, heavy infestations can damage large portions of the crown.

Peak Season: Present year-round in suitable climates, with periodic severe damage episodes

Identification & Symptoms

What to Look For

Scattered yellow spots on lower leaf surfaces
Brown and wilted leaves as feeding pressure increases
Tattered appearance of damaged leaves
Crown damage in severe infestations (up to 300 bugs per leaflet)
Unsightly damage to freshly opened leaves

Potential Damage

Progressive browning and wilting with increased feeding
Tattered appearance of affected leaves

Aesthetic damage reduces ornamental value
Rarely kills palms but causes significant unsightly damage

Lifecycle

Females lay small eggs along leaf mid-ribs, typically one egg per day. Eggs hatch in 8-9 days and development from egg to adult takes about one month. New palm leaves emerge monthly, providing continuous feeding opportunities.

Professional Treatment Approach

1

Systemic insecticide injection for palms

2

Monitor new leaf emergence for early detection

3

Focus treatment on palms over 12 feet tall

4

Regular inspection during peak activity periods

5

Maintain palm health to improve tolerance
