larva within the mine


Transparent blotch, quickly turning brown, starting at the leaf margin. Frass in scattered grains. Pupation outside the mine.

host plants

Salicaceae, narrowly monophagous

Populus x canadensis, nigra.

The reference by Taeger ao (1998a) and Chevin (1998a) of Populus alba and tremula as hostplants is rejected by Altenhofer (1980a, b) and Liston (1993b), who suppose a confusion with Fenusella glaucopis. However, in Altenhofer (2003a) again, next to nigra, alba and tremula are mentioned as hosts. Liston & Späth (2004a) consider only records from P. nigra trustworthy.

In the literature before 1949 also Acer campestre and platanoides are mentioned. This stems from confusion with Hinatara recta.


Minerende larvae around middle May (Altenhofer, 1980b; van Frankenhuyzen, 1974a); hibernation as prepupa in the ground (Güclü & Özbek, 1999a).


BE recorded (Fauna Europaea, 2008).

NE recorded (van Ooststroom, 1976a).

LUX recorded (Chevin, Ellis & Schneider, 2011a).

distribution within Europe

From Denmark to the Pyrenees and Italy, and from Ireland to Bulgaria (Georgiev, 2006a; Fauna Europaea, 2008).



Messa hortulana; Fenusella soenderupi, Hering, 1935.


Van Frankenhuyzen (1974a) describes a case of mass occurrence and damage to a windbreak around an orchard in the province of Zeeland. Also from Turkey damage was reported (Güclü & Özbek, 1999a)
