and case-bearer: The species spends two years as a larva, the first one-and-a-half
years in a small pistol-case, and in the second spring building
a long straight case which is dark brown and rather distinctive
lava lives from autumn until summer next year. In autumn a composite
leaf case is made, shaped like the handle of a walking stick. Early
in the following spring a tubular leaf case is made that in the
end is rather large (10 mm) and is positioned vertically on the
leaf; mouth angle 90° (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).
The larva is illustrated in Bladmineerders van Europa.
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The adult is illustrated in UKMoths.
genitalia are illustrated by the Lepidoptera Dissection Group.
