The caterpillar lives inside a needle of Abies alba from which it first eats the contents. It looks for a fresh green needle fallen on the ground between the other brown needles. It never changes to another needle. It hibernates inside the needle and continues to feed in springtime. Pupation in May.
The moths are active during the daytime but occasionally also come to light.
