Stigmella carpinella (Heinemann, 1862)
[Lepidoptera: Nepticulidae]

Hornbeam Pigmy


Nepticula carpinella Heinemann, 1862. Wien. ent. Monats. 6: 251.
Stigmella carpinella
(Heinemann, 1862).


Leaf-miner: Oviposition at the underside of the leaf, in the axil of a vein. The mine is a not very slender corridor. The first part is almost filled with frass; in the later part the frass lies in thick lumps. The trajectory of the mine is not angular, neither is it determined by the leaf venation. The discrimination between this mine and the one of Stigmella floslactella is difficult (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).

Yellow; see the description 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 not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
