Lifecycle NotesThe larvae are highly polyphagous, known as 'hairy caterpillars' due to their dense covering of long, irritating hairs, and can cause significant defoliation. Pupation occurs in a cocoon.
Identification TipsKey features include the dull brown, spotted forewings and the bright orange and black banded abdomen, which is often visible even when the moth is at rest. The hairy caterpillars are also very distinctive.
