Carpinus betulus, Germany (Baden-Württemberg), Badenweiler: in this hostplant the mine is much more determined by the venation of the leaf

mine

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 accommodate 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). The pale golden larva lies venter-upwards in the mine.
Sometimes it is difficult to separate the mines from those of S. floslactella; an additional difference then is in floslactella the oviposition invariably is in or very close to a vein axill, and the exit slit generally at the underside. The width of the frass line is less reliable as a character (van Nieukerken, 2021a).
