Phyllonorycter strigulatella mine



Elongated, lower-surface, in the end tubular contracted tentiform mine, usually starting at a small distance from the midrib. The lower epidermis with many weak wrinkles but no clear folds. Often several mines in a leaf. All frass is accumulated in an angle of the mine. Pupa in a white cocoon that is free from frass.

host plants

Betulaceae, narrowly monophagous

Alnus incana.

Referred to A. glutinosa by Maček (1999a). Huber (1969a) also mentions glutinosa, and even Ulmus glabra.


Larvae between June and October, in two generations (Buhr, 1964a).


BE recorded (Phegea, 2009).

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

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

Europa, excepted Ireland, the Iberian Peninsula and Greece (Fauna Europaea, 2009).




Lithocolletis strigulatella; some authors (including Frankenhuyzen & Freriks, 1976) used the name Ph. rajella for the present-day strigulatella.


The statement in Emmet ao (1985a) that the mine were upper-surface was a mistake (Emmet, 1994a).
