Leaf-mine: The larvae mines several leaves out, working from the base to the tip. It migrates to the next leaf by way of a short corridor in the bark of the twig. The larva therefore does not need to make openings in the needles for entrance or exit. Pupation external, in a spinning on the twig (Bladmineerders van Europa).

Larva: Body orange brown, spotted reddish brown. Head black, prothoracic plate dark grey, spotted black (Bladmineerders van Europa).

Pupa: Details unknown.

Adult: Not illustrated in UKMoths (check for update). The female genitalia, but not the male genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
