Ectoedemia albifasciella (Heinemann, 1871)
[Lepidoptera: Nepticulidae]

White-banded Pigmy


Nepticula albifasciella Heinemann, 1871. Berl. ent. Z.: 222.
Ectoedemia albifasciella
(Heinemann, 1871).


Leaf-miner: The mine begins with a narrow gallery following the midrib or a vein, and then becoming a rectangular blotch with frass gathered towards one end (UKMoths).

Oviposition on the upperside of the leaf, next to a vein. The first part of the mine is a narrow corridor, with a broad frass line, running along a vein. Usually the corridor runs away from the midrib, but often it runs along the midrib itself. The corridor widens abruptly into a squarish blotch, containing much frass. Often several mines in a leaf. Pupation external (Bladmineerders van Europa).

The mine is also illustrated in Belgian Lepidoptera.

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).

White with green gut-line, head pale brown (British leafminers). The larva is yellowish white with a light brown hread; ganglia inconspicuous; ventral plates present but indistinct (van Nieukerken, 1985a). See Gustafsson and van Nieukerken (1990a) for a description of the larva (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 male and female genitalia are illustrated by the Lepidoptera Dissection Group.
