Stigmella glutinosae (Stainton, 1858)
[Lepidoptera: Nepticulidae]

White-barred Alder Pigmy


Nepticula glutinosae Stainton, 1858. Entomol. Ann.: 96.
Nepticula distinguenda
Heinemann, 1862. Wien. ent. Monats. 6: 305.
Stigmella glutinosae
(Stainton, 1858).


Leaf-miner: A gallery with frass partly dispersed, but sometimes in a thin line (as S. alnetella ). The moths must be bred through to distinguish between this and S.alnetella (British leafminers).

Oviposition at the leaf underside. Then a full depth, fairly slender corridor, often several in a leaf. Frass line very variable, sometimes coiled, mostly more than on third of the width of the corridor. 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).

Yellow, with a grey-brown patch on the prosternum (Johansson et al., 1990a). The larva mines venter-upwards (Emmet, 1983a). Abdominal segment 1 ventrally not spinulose (Johansson et al., 1990a) (Bladmineerders van Europa).

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

Adult: NThe adult is not illustrated in UKMoths (check for update). The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
