Leaf-mine:
The larva initially forms a gallery along the midrib, which then
goes out along a vein. The end of this gallery is then excised to
construct the first case. It then feeds close to this and makes
several small mines (British
leafminers). The leaf-mine and case are also illustrated in
Nederlandse
bladmineerders.
