Stigmella aeneofasciella (Herrich-Schäffer, 1855)
[Lepidoptera: Nepticulidae]

Brassy Pigmy


Nepticula aeneofasciella Herrich-Schäffer, 1855. Syst. Bearb. Schmett. 5: 353.
Stigmella aeneofasciella
(Herrich-Schäffer, 1855).


Leaf-miner: A slender gallery, leading to blotch (British leafminers).

Egg on the underside of the leaf. The first part of the mine is a long, slender corridor, rather straight, often folllowing a vein or the leaf margin. The frass here is black, lying in a very narrow central line. The corridor abruptly widens into a large blotch, where the the frass lies irregularly scattered (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).

Pale greenish yellow. See Gustafsson and van Nieukerken (1990a) for an extensive description (Bladmineerders van Europa).

Larva is a pale watery greenish yellowish (whereas S. poterii its yellow) (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 illustrated in UKMoths. The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
