As lagartas quando nascem alimentam-se em primeiro lugar da casca do próprio ovo, e só depois se juntam numa teia para se alimentarem onde permanecem durante o Inverno. Na Primavera as lagartas continuam a viver gregáriamente. No final do desenvolvimento larvar este comportamento é abandonado, e as lagartas dispersam-se para se alimentarem individualmente antes de crisalidarem. A borboleta eclode ao fim de três semanas.

The larva eats the majority of its eggshell on hatching before joining a communal larval web. Groups of larvae leave the web to feed side by side but remain within the web through the winter while still very small, in the 3rd instar. After emerging in the spring, the larvae continue this pattern of communal living, continuing to forage in groups. Larvae are particularly sensitive and will drop from the foodplant if disturbed. As the larvae grow, they tend to form smaller groups that form sub-communities, each group creating their own web on which to rest. Ultimately, the gregarious behaviour is abandoned, and the fully-grown larvae disperse to feed individually prior to pupation. This pupa stage typically lasts around 3 weeks, depending on temperature.
