Leaf-mine: Oviposition in the base of the midrib, without giving rise to an oviposition scar. The larva initially bores inside the midrib. Later it leaves the midrib, forming a broad corridor in the blade, that widens into a blotch. Finally the legless larva pupates in a globular cocoon inside the mine. Because the mine develops at a time that the leaf is fully developed, mined leaves are not disfigured (Bladmineerders van Europa).

Larva: Details unknown.

Pupa: Details unknown.
