Tubular leaf case. The case is almost barrel-shaped, with a large leaf fragment that, while withering, folds itself untidily around the tube.
Before a larva leaves a mine to start on a fresh one, it often detaches the upper epidermis by cutting along the sides of the mine; often completely, sometimes only partially. The detached epidermis falls off or, when it is only partially loosened, dries and curls (Emmet, 1980a).
The young larva, in autumn, initially mines a gallery. A silken-lined side branch, positioned along a thick vein, serves as a resting place during feeding pauses. After this period the larva makes an oval blotch, excises it to form its first case, and goes into hibernation.
Larvae are full-fed in Britain in end August, but continental authors write October (Emmet ao, 1996a).
