Stigmella glutinosae is a moth of the family Nepticulidae. It is found in all of Europe (except Iceland, Spain and the southern part of the Balkan Peninsula).

The wingspan is 4.4–5.2 millimetres (0.17–0.20 in).A small, dark bronze-coloured moth. The antennae are filamentous, dark and about half as long as the forewing. The innermost, greatly expanded joint is white. The head is yellow-haired, the body dark except for a white "collar" just behind the head. The forewings are glistening, dark bronze-brown with a rather narrow, silvery-white transverse band at about two-thirds of the wing. The hind wing is narrow, grey, with long fringes. The species is very similar to several other Stigmella species, but the white collar can be a good characteristic of this species.To be certain requires microscopic examination of the genitalia.

Forewings bronze-fuscous, sometimes purplish-tinged a narrow whitish fascia beyond middle; apical area beyond this dark purplish-fuscous. Hindwings light grey.
