Leaf-mine:
The larva of this species creates a gallery mine. The mine is
similar to those of the alder-feeding Nepticulidae, but is generally
shorter, with the larval exit-hole on the upperside of the leaf
rather than the underside. After vacating the mine, the larva grazes
on the underside of the leaf in the manner of other Bucculatricidae
(UKMoths).
The mine is illustrated in British
leafminers and Nederlandse
bladmineerders.
