Ectoedemia turbidella (Zeller, 1848)
[Lepidoptera: Nepticulidae]

Grey-poplar Pigmy


Nepticula turbidella Zeller, 1848. Linn. Ent. 3: 321.
Nepticula populialbae
Hering, 1935. Z. Pflkrankh. PflPath. PflSchutz. 45: 7.
Ectoedemia turbidella
(Zeller, 1848).


Galler and Leaf-miner: A gall in petiole, later mine in leaf-blade, in 'green island' (British leafminers).

The egg is placed on the petiole, about a cm below the base of the leaf; often one egg at either side. The larva first bores in the distal part of the petiole, that shows a local swelling. When the larva reaches the leaf it makes an elongate triangular blotch between the leaf margin and the first side vein, or, less frequently, between midrib and side vein. Frass in two bands, parallel to the sides of the mine, created by the passage of the larva when it retreates into the petiole. The larva mainly feeds at night. 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).

Whitish, no ventral plates; see Gustafsson and van Nieukerken (1990a) for 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 illustrated in UKMoths. The female genitalia, but not the male genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
