A rather rare species in Belgium.
Native
The adults have been observed from June till August. They are active towards dusk and come to light.
The young larva mines inside a needle of Picea abies or Picea sitchensis, and it hibernates in that plates half-fed. Later on, it constructs a silken tube along which it retreats to deposit frass in the first mined needle.
Pupation in a white cocoon in the larbal tube or amongst leaf-litter.
