Small, transparent, irregularly shaped full depth mines, less than a square cm, often several in a leaf. Frass granular, little or missing. After some time the larvae leave the mines and continue feeding freely at the leaf underside or under a folded leaf margin.

host plants

Asteraceae, narrowly oligophagous

Petasites hybridus; Tussilago farfara.


Larvae from July till November; a spring generation, that occurs in March – April, bores in the stalks of the inflorescence (Hering, 1957a).


BE recorded (Phegea, 2009).

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

LUX recorded (Fauna Europaea, 2009).

The description of the mine above is based on Hering (1957a). However Hart (2011a), giving a detailed description of the biology, writes of a single generation, of which the larvae live in the flower stalk an the capitula. No word on mining.
