detail, last section of the mine
larva, ventral view
The first section of the mine is a long and very narrow gallery running in the direction of the leaf tip. At a given moment the galley switches direction and simultaneously becomes broader, ultimately becoming as wide as the leaf itself. Hering (1957a) describes the mine as flat and quite shallow, giving it a greenish, rather than whitish appearance. Frass initially in the oldest, upper part of the mine, later in strings. The larva can leave its mine and restart elsewhere. Normally only one larva per mine, but sometimes two or even three mines in a leaf. Pupation outside the mine (Bland, 1996a; Traugott-Olsen & Schmidt Nielsen, 1977a).
