Newly hatched larvae are uniformly brown with a dark head. The body colour lightens as the larvae matures. Final instars are grey with a black head and a single dark
stripe running along the back and a whitish line along each side. Clumps of long white hairs arise from orange warty pinacula along the length of the body.
Early instars feed together on leaves and hide in soil and leaf litter. Later instars form a communal silken nest. Feeding larvae skeletonise leaves. Mature larvae leave
the tree in a line to locate a pupation site. Urticating hairs from the larvae cause irritation and allergic reactions in humans and pets.
