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


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


Leaf-mine: 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: 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: Details unknown.

Adult: Not included in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
