Coconut rhinoceros beetle

Start with the beetle, the damage, and the official response.

CRB (Oryctes rhinoceros) is an invasive beetle that can damage palms and other host plants. The details and current response change by island—use the official sources linked here for the latest guidance.

Possible signs

Adults are large, dark beetles with a horn. Palm damage can include bore holes and distinctive V-shaped cuts in emerging fronds. Similar insects and other causes of damage exist, so photographs and official identification guidance matter.

Current status, not a static map

CRB distribution and response activity evolve. Rather than maintain a potentially stale map, CrowCRB directs readers to the CRB Response current-status page ↗ and island organizations for updates.

Prevention and management

Movement and handling of potential breeding material can carry real consequences. Check official guidance before moving mulch, compost, soil, green waste, or host material; treatment and transport requirements may vary. Start with the CRB Response management guidance ↗ and the resources below.
