A very rare species in Belgium, long time only known from one observation in May 1941 at Sourbrodt near Malmédy (LG). Found again after 2000, but only a few scattered observations.
The larvae are full-grown in April.
The adults can be easily observed while resting on tree trunks and later come to light. It is known that they are attracted to the pheromone of Synanthedon culiciformis.
The adults have been observed mainly in May and June.
The caterpillar lives in several species of mushrooms or fungi like: Inonotus radiatus, Piptoporus betulinus, Fomes fomentarius, Stereum rugosum, Daedalea quercina, Bjerkandera adusta, Formitoporia punctata and Phellinus tremulae with a preference for those growing on: Fagus, Carpinus or Betula. Also in wood permeated with fungal mycelia.
