Stigmella hybnerella (Hübner, 1813)
[Lepidoptera: Nepticulidae]

Greenish Thorn Pigmy


Tinea hybnerella Hübner, 1813. Samml. Europ. Schmett. Tin. 34: 236.
Stigmella hybnerella
(Hübner, 1813).


Leaf-miner: The frass linear in early gallery, widening to blotch with dispersed frass (British leafminers).

Oviposition at random point of the leaf, either at upper- or lower-surface. First a quite slender corridor is made, with a relatively broad, continuous, frass line, that always leaves a clear margin at either side; the corridor winds freely through the leaf. This initial corridor often abruptly changes in direction, widens into a blotch that mostly lie along the leaf margin. Pupation outside 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).

The larva is whitish (British leafminers).

Described by Gustafsson and van Nieukerken (1990a) (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 genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
