  • Restricted distribution. Asia, Africa, Oceania. Present in Australia, Cook Islands, Fiji, French Polynesia, Vanuatu.
  • A major pest. Larvae bore into fruits of Tahitian chestnut creating holes with frass, making them inedible. Light grey, up to 15 mm long, caterpillar with 8 spots on each segment. Moths, brown with yellow tips to forewings.
  • Cultural control: ideally, remove fallen fruit - but trees grow wild so unlikely to make an impact.
  • Chemical control: Not an appropriate measure: trees large, wild and larvae protected inside fruits.
Common Name

Tahitian chestnut fruit borer.

Scientific Name

Cryptophlebia pallifimbriana. It is a moth of the Tortricidae
