Habitat

Forests and woodland

Reproduction

Eggs are laid on Lantana leaves. The larvae feed through middle leaf layers, forming mines—usually two per leaf, each containing a single larva. Pupation occurs in the leaves. Development from egg to adult takes 31–52 days. Adults live for 6–9 months, but may enter a period of inactivity during winter when conditions are unfavourable.

Food

Larvae feed on lantana leaves. Damaged leaves can be shed, causing the plant to become stunted.
