Stem-mine: The eggs are laid in the stem in the current year's growth and the whitish mine progresses up the stem terminating at the base of the leaf. The larva curls over the leaf edge to pupate (Langmaid and Corley, 2007).

Oviposition on a young twig. From there a long corridor is made in the bark, up to 30 cm in length, running up or down, hardly widening. Finally the corridor enters a petiole and a leaf where, close to the base, at the upperside, a white cocoon is spun in which pupation takes place (Bladmineerders van Europa).

The mine is also illustrated in British leafminers.
