mine

Young larvae make a short, spiralled corridor (Bland ao, 2002a, describe them as “typically U-shaped”). This stage is followed by an irregular, sometimes branching, greenish-white blotch (Jansen, 1999a). In their finale stage the larva lives free in a silken tunnel among the leaves.

synonyms

Gnorimoschema nitentellum.

notes

Halophilous species.

According to Patočka & Turčáni (2005a) the larve is not a miner, but “feeds on the seed heads of Chenopodium”. This can be a simple mistake, but may also indicate a different interpretation of the species.
