The larva spins some leaves together, especially on young shoots. It hibernates in the spinning which it vacates when fully fed in spring. It drops to the ground and spun a silken cocoon between leaf-litter on the ground. It pupates in that cocoon around April.
During the day they are easily disturbed from rest amongst the branches of spruce. They fly on sunny afternoons but are more active towards sunset and later come to light.
The adult can be seen from March till late July, occasionally later. Specimens are regularly found in houses during the winter period.
It inhabits coniferous woodland and plantations.
