Coptrotriche gaunacella (Duponchel, 1843)
[Lepidoptera: Tischeriidae]


Elachista gaunacella Duponchel, 1843. Hist. Nat. Lep. Fr. Suppl. 4: 319.
Emmetia gaunacella
(Duponchel, 1843)
Coptrotriche gaunacella (Duponchel, 1843).


Leaf-miner: Upper-surface blotch. The inner wall is lined with much silk, giving the mine a white colour. The silk also causes the mine to contract, pulling the leaf margins upwards; the mine can be almost completely hidden from view in this way. All frass is ejected from the mine. Pupation within the mine (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).

Greenish white; head an prothoracic plate dark brown (Bladmineerders van Europa).

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

Adult: The adult is not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissction Group (check for update).
