Leaf-mine:
The young larvae mine the leaves, causing a gallery followed by
a semi-translucent blotch on the upper surface of the leaf. It then
vacates this and folds the edge of a leaf down to feed within, usually
twice, before pupating externally among detritus (UKMoths).
The leaf-mine is also illustrated in British
leafminers and Nederlandse
bladmineerders.
