Leaf-miner: Blotch clouded, with some green matter left in mine. Several
larvae (2-4) in one mine (British
full depth blotch, adjacent to the leaf margin. The mine is not
completely eaten out, which gives it a greenish or off-white appearance.
Frass in threads, that seem to be somewhat shorter than in other Eriocrania's. The mine harbours 2-4 strikingly hyaline larvae.
Pupation in the ground. Older mines wither and wear off; in summer
no trace of them is left (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).
Small, translucent white (British

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
