The eggs are oviposited in batches of ca. 5 specimens on powdery lichen or bare wood. They hatch in about 20 days in July–August.
The hatching larvae immediately burrow into the lichen and spins a silken tube from which it feeds on the lichen. The tube is covered with dark frass. The larva lives under dead bark of various trees and shrubs, in dead wood, on fences etc. It has also been observed in mite galls on Salix. It constructs a whitish silken tube from which it eats. It hibernates.
Pupation in the larval feeding place.
The adults are active at dusk, they have been observed flying around Taxus and Buxus. They also come to light.
