Rather narrow gallery, untidy and sometimes branched, usually 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, anf the frass is scattered irregularly. Larvae without feet. Pupation outside the mine (Hering, 1957a).
