Scolioneura betuli: mine on Betula pendula

the frass of mining sawflies is dry and does not stick to the walls of the mine; it accumulates at the lowest point like grains of pepper in an envelope.

Scolioneura betuleti: mines on Alnus viridis

Alnus viridis, Scotland, Orkney @ Derek Mayes

Scolioneura betuleti: larva



Large, transparent, in fresh condition pale green blotch that begins at the leaf margin, without an accumulation of frass.

host plants

Betulaceae, oligophagous

Alnus viridis; Betula alleghaniensis, ermanii, humilis, obscura, papyrifera, pendula, pubescens.

The occurrence on Alnus viridis is understandable, because this species is considered an intergeneric hybrid between Alnus and Betula. The reference by Maček (1999a) of Alnus glutinosa, however, is quite surprising.




BE recorded (Fauna Europaea, 2008).

NE waargenomen (van Ooststroom, 1976a).

LUX recorded (Fauna Europaea, 2008).

distribution within Europe

Entire Europe, with possible exception of Ireland and the Balkan Peninsula (Fauna Europaea, 2008).



Scolioneura betulae (Zaddach, 1859); S. vicina Konow, 1894. For some time it was thought that S. vicina were an independent species, based on a a phenology different from that of betuleti; this has bene refuted.


Especially numerous on seedlings.
