Worldwide distribution. In the tropics and sub-tropics. Most commonly on members of the citrus family, e.g., cumquat, grapefruit, lime, and sour orange. An important pest.
A moth larvae damages new shoots of trees; worse in nurseries and on young trees.
Eggs laid singly near midribs of young leaves; larvae hatch, mine the surface layers causing leaves to distort. Mines fill with air and look silvery; and they have a central line of excreta.
Natural enemies: parasitoid wasps.
Cultural control: prune damage on nursery plants and young field trees, and collect and burn the prunings.
Chemical control: leafminer worse where pesticides are used against other insects (e.g., Diaphorina that spreads citrus greening or huanglongbing disease). Use pest oils at start of main flush when shoots are 20-30cm long.
