Broad corridor, widening into a large transparent blotch with 1 or several, proportionally very large larvae that quickly completely mine out a leaf, then move to another leaf. At the start of the first mine at the leaf underside 1 or more oval egg shells. Pupation outside the mine.

host plants

Polygonaceae, monophagous

Fallopia aubertii, baldschuanica, convolvulus, dumetorum.

Perhaps occasionally on Persicaria spp. A reference by Brischke of Ipomoea (as P. grossa) is questionable (Hering, 1957a).


Larvae found from June to September.


BE recorded (Gosseries & Ackland, 1991a).

NE recorded (de Meijere, 1939a).

LUX not recorded (Fauna Europaea, 2008).
