initially in an underside epidermal mine then folds the leaf down
larva first makes a distinctly folded lower-surface tentiform mine.
After some time the mine is vacated and the larva lives free then
in a leaf margin that has been folded downwards and is secured with
silk. In small leaves the two halves are simply spun together in
a pod. Two of these leaf folds are made and eaten out. The folds
with the free living larva strongly resembly the work of a sawfly
larva on the same plant; however, then no silk is used to anchor
the leaf margin (Bland, 1993a) (

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).
See Bland (1993a).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
See Patocka and Turcáni (2005a).
