Stigmella microtheriella (Stainton, 1854)
Corylus avellana, Amstelveen
Carpinus betulus, Germany (Baden-Württemberg), Badenweiler: in this hostplant the mine is much more determined by the venation of the leaf

Corylus avellana, Nieuwendam: also in the very first part of the corridor lies the frass in a narrow central line
Corylus avellana, Amstelveen: very atypical mine, with over-abundant frass
Oviposition at the underside of the leaf, mostly close to a vein. The mine is a long, very slender corridor; even towards the end hardly wider than necessary to accomodate the growing larva. Frass in a narrow central line. The shape of the mine differs somewhat between the hostplants. In Carpinus the mine closely follows a heavy vein over a long distance; also the mine tends to be somewhat shorter and broader, and the frass often lies in a more diffuse line. The mines in Corylus are not so strictly defined by the venation and the frass line is narrower (Emmet, 1983a; Johansson ao, 1990a). Sometimes it is difficult to separate the mines from those of S. floslactella; an additional difference then is that even in the very first part of the corridor the frass of microtheriella lies in a narrow line, while the frass of floslactella seems to fill the entire corridor there. The pale golden larva lies venter-upwards in the mine.
Larvae in end-June – July, and October – November (Emmet, 1983a).
