mine lighted from behind
Egg at the underside of the leaf, independent of the venation. The corridor is narrow from start to end, and compressed on a small space, sometimes following the leaf margin for a while, more often along a major vein. Frass in a narrow, regularly interrupted central line. In thick leaves the frass line is broader, and the corridor is shorter.
Larvae n July and August (Emmet, 1983a).
BE recorded (Baugnée & van As, 2012a).
NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2009).

distribution within Europe

Green (Emmet, 1983a; Schoorl ao, 1985a; Gustafsson & van Nieukerken, 1990a).
Nepticula magdalenae. In the older literature before 1976 (but also in Emmet, 1983a) the name nylandriella is used for what is understood now as magdalenae; the current St. nylandriella is addressed then as aucupariae.
On Apple the mine can be confused with that of S. desperatella, a species not known from the Benelux, but which presence cannot be excluded. The only reliable difference is that the larvae of magadelenae have on abdominal segment 9 a field of fine spines, that is lacking in desperatella (Gustafsson & van Nieukerken, 1990a).
