Leaf-mine:
A gallery filled with green frass. In the older gallery the frass
turns brown (British
leafminers).
A
narrow corridor. The coiled frass is greenish (blackish brown in

is filled up, making the mine rather inconspicuous. The sides of
the corridor are not straight, rather irregular (Bladmineerders
van Europa).
Larva:

et. al(1985a) for an extensive description (Bladmineerders
van Europa). The
