two more, same sample


Egg at the underside of the leaf. The mine is a small compact corridor, rather strongly widening towards the end, mostly in a vein axil. Colour of the mine often orange. Frass in a broad, irregular central line.

host plants

Rosaceae, monophagous (?)

Malus baccata, domestica, floribunda, sylvestris.

In the, mainly older, literature repeatedly is spoken also of Cydonia oblonga, next to Cotoneaster nebrodensis and Sorbus aria. The only nepticulid associated with Cydonia is Stigmella oxyacanthella, but it is hardly conceivable that incognitella could be confused with that species.


Larvae in October – November, often in green islands (Johansson ao, 1990a).


BE recorded (Phegea, 2009).

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

LUX recorded (Fauna Europaea, 2009).

distribution within Europe

All Europe except Ireland (Fauna Europaea, 2009).


Bright yellow to orange. See Briolini (1961a) and Johansson ao (1990a) for a description of the larva.


Nepticula incognitella; Stigmella pomella (Vaughan, 1858); Stigmella mali (Hering, 1932).


Has in the past several times caused damage in apple crops (van Frankenhuyzen, 1965a).
