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

larva

mine

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.

phenology

Univoltine. Larvae in August – October.

BENELUX

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).

larva

synonyms

Scolioneura betulae (Zaddach, 1859); S. vicina Konow, 1894.

notes

Especially numerous on seedlings.
