Leaf-mine:
Long,
irregular, whitish linear mine which turns brown when older and
has conspicuous frass in large widely-spaced black lumps. Pupation
external (Spencer, 1976:
371 (fig. 647A), 372).
Very
long, initially whitish, later brownish, upper-surface corridor,
frequently starting near the leaf tip, often crossing itself. Frass
in strikingly large black lumps, more widely spaced than their own
diameter. Pupation outside the mine; exit slit in upper epidermis
(Bladmineerders van Europa).

Details unknown.
Puparium:
Posterior spiracles each with 25 or more bulbs (Spencer,
