Bionomics

The eggs are deposited in a group at a terminal shoot of the foodplant, often on thin branches and covered with a spinning in which the hairs of the abdominal last segment of the female are used. The nests can be found both on low bushes and high in the trees. The caterpillars live gregariously in a tough, white, silken web from where they feed on the adjacent leaves. The species hibernates in the pupal stages and sometimes the pupa hibernates several times.
The adults are active at night and come sparsely to light.

One generation a year from late February till early April.
