Sorbus aucuparia, Nunspeet

mine

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.

host plants

Rosaceae, oligophagous

Amelanchier ovalis(?), spicata; Cotoneaster integerrimus; Malus sylvestris; Sorbus aria, aucuparia, ? torminalis.

phenology

Larvae n July and August (Emmet, 1983a).

BENELUX

BE recorded (Baugnée & van As, 2012a).

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

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

From Scandinavia and Finland tot the Pyrenees, Italy, and Bulgaria, and from Ireland to Central Russia and the Ukraine (Fauna Europaea, 2009).

larva

Green (Emmet, 1983a; Schoorl ao, 1985a; Gustafsson & van Nieukerken, 1990a).

synonyms

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.

notes

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).
