Leaf-miner
and case-bearer:
The first case is cut out of an oval mine in the centre of the leaf.
The second and third, final, case are excised out of a mine along
the leaf margin, and therefore have a serrate dorsal keel. The final
case is a spatulate leaf case, 6-7 mm long, with a bivalved, square-cut
rear end. The mouth angle is c. 45°. See Emmet et al. (1996a)
(Bladmineerders
van Europa).
