on the leaf underside. The mine begins as a long, winding corridor
with a broad frass line that is red brown at first, black brown
later. The corridor abruptly widens into a slightly inflated blotch where the frass lies concentrated in the centre and where pupation in a coccon takes place. In preparation the larva has
cut a semicircular exit slit in the leaf underside, near what later
will be the front end of the cocoon (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).
In a cocoon (Bladmineerders van Europa).
The adult is illustrated in UKMoths.
The male and female genitalia are illustrated by the Lepidoptera Dissection
