Leaf-miner: The larvae mine leaves at first, forming a blotch mine, later descending
to the ground in a portable case and feeding on dead leaves (UKMoths).
is by way of an ovipositor, therefore no egg shell visible. The
larva makes a small, roundish, blotch; often several in a leaf.
Already after its first moult it makes an excision out of the mine,
in size almost equal to the blotch (3-4 mm). Thus sandwiched it
drops to the ground and continues feeding on dead leaf material
(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).
Mining Incurvaria-larvae, while resting, take a horse-shoe like
posture, unlike the larvae of Antispila species (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 and the Encyclopedia
of Life. The male and female
genitalia are illustrated by the Lepidoptera Dissection Group.
The ovipositor comb of masculella is illustrated in British
leafminers alongside pectinea and oehlmanniella.
