mine

Oviposition within the leaf tissue. The mine begins as a narrow corridor along the midrib., not far from the leaf tip. Then a large full depth blotch is made that can occupy the entire leaf. The brown frass is glued to the upper epidermis, and makes the mine opaque; only the sides remain transparant. Pupation outside the mine.

Thymelaeaceae, narrowly monophagous

Daphne gnidium.

Larvae in February and June (Hering, 1957a).
