larva enters a needle by making a circular entrance, which is closed
with silk. The needle is more or less completely mined out, after
which the larva leaves the mine either througth the first opening,
or by making a new one. This procedure is repeated a number of times.
The mines hardly contain any frass. Pupation in the ground (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 of aurulentella has body dirty green, reddish towards the end. Head shining black, prothoracic
and anal plate blackish brown with an olive brown centre (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
See Patocka and Turcáni (2005) (Bladmineerders van Europa).
The adult is not illustrated in UKMoths (check for update). The genitalia are not illustrated by tht Lepidoptera
