Stigmella lemniscella (Zeller, 1839)
[Lepidoptera: Nepticulidae]

Red Elm Pigmy


Lyonetia lemniscella Zeller, 1839. Isis, Jena 23: 215.
Nepticula marginicolella
Stainton, 1853.
Stigmella lemniscella
(Zeller, 1839).


Leaf-miner: The frass is dispersed in early part of mine (British leafminers).

Oviposition at upper or lower surface. Rather slender corridor mine, hardly widened in the end. The corridor often follows the leaf margin for some distance. The first section of the corridor is almost entirely filled with frass. Frass in the later part of the mine in more or less clear coils. Pupation external; exit slit invariably in upper epidermis (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 yellow (British leafminers). The larva is also illustrated in 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 by Rob Edmunds. The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
