mine

Small (up to 10 mm long), lower-surface blotch near the leaf margin, with a brownish lower epidermis. The mine in fact is a tentiform mine, but so little silk is produed that the blotch hardly contracts at all. The mine is preceded by a quite short corridor, that is overrun by the later blotch.

The older larva leaves its mine and starts feeding under a flap of the leaf margin that is folded down and fixed with silk on the blade underside. Two or three such folds are made, not necessarily on the same leaf. The fact that sometimes no leaf rolls are made, but parts of the leaf are folded downwards rather makes one think of the work of a Parornix (Emmet, Watkinson & Wilson, 1985a).
