Very untidy, bivalved, lobe case of 7-8 mm. The mouth angle is 90°,
causing the case to be perpendicular to the leaf (Bladmineerders van Europa).
Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).
