Stigmella suberivora (Stainton, 1869)
[Lepidoptera: Nepticulidae]

Holm-oak Pigmy

Stigmella suberivora
(Stainton, 1869).


Leaf-miner: A broad twisting gallery, almost frass filled (British leafminers).

Egg at the upperside of the leaf. The mine is an irregular, broad corridor with a conspicuous, broad, black frass line that almost fills the gallery, leaving only a narrow transparant zone at either side. Pupation external (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).

Yellow; laying dorsum upwards in the mine. Gustafsson and van Nieukerken (1990a) give a description (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 Dissection Group (check for update).
