The larva spins a silken tube from which it feeds on the surrounding fungi. The tube is usually hidden behind old bark.
Pupates in a silken frass-covered cocoon in the larval habitation during April–May.
The adults are sometimes found resting on tree trunks during daytime, later they come to light.
Flight periods
The adults fly in a single generation a year from early May till June.
