Life history cycle
The Emperor Gum Moth glues its eggs onto eucalypt leaves, which the large green caterpillars eat when they emerge. The caterpillars are covered in protective spines and build a tough cocoon in which to pupate. They may reinforce this cocoon with bark and remain inside it for one or more years depending on environmental conditions. The adults emerge in summer. The life span of adult Emperor Gum Moths is limited to only a couple of weeks because they are unable to feed. They must rely solely on the energy consumed as caterpillars.
