Observed on


The larva feeds on the fungus Daldinia concentrica which is growing on burnt Ulex or young Betula. It makes a silk-lined gallery inside the fungus and later, when fully fed, it burrows into dead wood where it hibernates and pupates the following spring. The pupae may also be found in the fungus.
