Leaf-mine:
The larva makes a large number of untidy full depth mines. The mines
contain hardly or no frass. The opening made by the larva in the
underside of the leaf is irregular roundish, sometimes more of a
slit, large in proportion to the size of the mine, and usually positioned
at the side of the mine. The larva mines until just before the pupation,
that takes place externally (Bladmineerders
van Europa).
Larva:
Dull flesh-coloured with two yellow white dorsal lines; head black,
prothoracic plate with dark marking (Bladmineerders
van Europa).

Details unknown.

county may relate to an adjacent vice county - for included datasets see NBN Grid map below).
