Stigmella glutinosae (Stainton, 1858)

white-barred alder pigmy

Stigmella glutinosae mine

Alnus glutinosa, Ackerdijkse Plassen

Stigmella glutinosae mine

Alnus glutinosa, Belgium, Viroinval


Oviposition at the leaf underside, always against a vein. 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.


Betulaceae, monophagous

Alnus glutinosa, cordata, incana, orientalis, subcordata, viridis.


There are two generations per year (Johansson ao, 1990a).


BE recorded (Phegea, 2009).

NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera,nl, 2009).

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

Entire Europe, except the Balkan peninsula and possibly Spain (Fauna Europaea, 2009); Cyprus (Barton, 2015a).


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


Nepticula glutinosae; Stigmella rubescens (Heinemann, 1871).


It is not well possible to definitely discriminate a single mine from the one of Stigmella alnetella, unless a larva is available.

Erik van Nieukerken (pers. comm.) found the mine depicted below on Birch. The mine resembles St. luteella, but lacks the characteristic beginning. A study of the larval DNA showed that glutinosae was involved. Obviously, it now has to be established how frequently the species uses Birch as as hostplant.
