- Unknown distribution. Recorded from Papua province (Irian Jaya), Indonesia and Fiji. Only found on Malay (rose) apple.
- Damage done by larvae mining the leaves, often between the veins, causing them to shrivel and die. Only a few leaves affected on any one tree.
- Adults are small moths with distinctive white semi-circular spots on forewings; hindwings fringed. Antennae longer than body.
- Spread occurs in the wing and via the trade in plants.
- Cultural control: squash larvae in tunnels between finger and thumb; removed infested leaves and burn.
- Chemical control: possibly needed in nurseries. Use systemic imidacloprid, or synthetic pyrethroid.
