A rare but widespread species in Belgium, with most observations in the eastern part of the country. Can be confused with Denisia similella.
The adults rest during the day on tree trunks, but they become active at dusk and come to light.
The adults fly from end of May till August.
The larva lives under dead bark, in decayed wood and amongst other plant material from conifers like: Abies alba, Picea and Pinus.
Pine forests, open places in mixed forests.
