The species hibernates in the larval stage. The caterpillar spins a whitish, silken gallery between mosses or lichens growing on old trees. Sometimes many of these silken galleries occur close to each other, forming a network in the moss. This has lead to the idea that the caterpillars live gregariously.
The adults rest during the day on tree trunks, but they have also been observed flying around patches with mosses or lichens, even when these were growing on rocks. They come to light.
