Leaf-miner
and case-bearer:
A straw-coloured to grey, slender, three valved tubular silken case.
Mouth angle 45° to 60°. The case resembles that of Coleophora
trochilella, but the case is more slender, the mouth is
narrower and the constriction behind the mouth less deep. (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).Strongly resembling the larva of Coleophora
trochilella, but the rear margin of the pronotum has two
dark spots (Emmet et al., 1996a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
