Leaf-mine: Long, full depth mine, starting at an oviposition scar, mostly in
the distal part of the midrib; the scar may be swollen and gall-like.
Frass line variable in width, sometimes quite broad. Usually the
corridor loosely follows the leaf margin, and the part of the leaf
that is cut off from the centre dies off. The larvae live in spring,
when the leaf is unfolding; later in summer affected leaves are
recognisable because the tip of the leaf and parts of the marginal
teeth are missing, by remnants of the corridor and by a general
disfiguring of the leaf. The larva leaves the mine before pupation
(Bladmineerders
van Europa).
