Leaf-miner: The young larvae mine the leaves, causing a gallery followed by
a semi-translucent blotch on the upper surface of the leaf. It then
vacates this and folds the edge of a leaf down to feed within, usually
twice, before pupating externally among detritus (UKMoths).
mine begins as an inconspicuous epidermal corridor, mainly recognisable
by its reddish brown frass line. In the next instar a blotch is
formed. The mine not starting over a vein, rather lies between two
veins. The colour initially is silvery, but soon the mine gets a
characteristic onrange-brown tinge. Usually, but by no means invariably,
the mine is upper-surface; lower-surface mines keep their original
silvery colour. Silk is deposited witihin the mine, but in little
quantities and the mine contracts only lightly. The mine hardly
contains any frass. After some time the larva leaves the mine and
then lives free in a leaf margin that has been folded downwards
and fixed with silk. Two such folds are usually made, and eaten
out to the upper epidermis (Bladmineerders van Europa).

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