A very local and rare species in Belgium. Most observations in the Kempen area.
The adults fly in sunny afternoons after hibernation, and later they come to light. They have been observed from September till late April.
The larva lives in a slight web on the top shoots, preferring the flowers of Calluna, Erica, Vaccinium myrtillus or Vaccinium vitis-idaea. Pupation in an earthen cocoon, rarely in the feeding place.
