Leaf-mine: Rather narrow corridor, untidy and sometimes branched, starting from the base of the leaf, in particular the midrib. Sides of the corridor irregularly eaten out, not really parallel. Frass mostly present, and then in a central line. The larva is capable of leaving the mine and start a new one elsewhere. These later mines are much broader, and the frass is scattered irregularly. (Bladmineerders van Europa).

Larva: The larvae are legless. (see Keys in Bladmineerders van Europa).

Pupa: Details unknown.

Hosts in Britain: Unknown.

Hosts elsewhere:

Time of year - larvae: Almost throughout the year (Hering, 1957).

Also recorded in the Republic of Ireland (Alonso-Zarazaga in Fauna Europaea).
