A very local and rare species in Belgium, only mentioned from three provinces.

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.

The adults fly in sunny afternoons after hibernation, and later they come to light. They have been observed from September till late April.
