Scolioneura vicina: 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 vicina young mine

Betula pendula, Castricum: very young mine, 9.v.2011

mine

Large, transparant, in fresh condition pale green blotch that begins at the leaf margin, without an accumulation of frass. The complete mine may occupy almost the entire leaf. Mine and larva are indistinguishable from those of S. betuleti, but vicina larvae live from mid May till mid June, while the larvae of betuleti are found only in August – October (Altenhofer & Taeger, 1998a).

host plants

Betulaceae, monophagous

Betula papyrifera, pendula, pubescens.

phenology

Univoltine. Larvae from mid May till mid June.

BENELUX

BE recorded (Fauna Europaea, 2008).

NE Recorded (Ellis, not rare).

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

distribution within Europe

From Sweden and Finland to Austria, and from Britain to Germany (Edmunds, 2008a; Fauna Europaea, 2008).

synonyms

A study by Leppänen, Altenhofer, Liston & Nyman (2012a) has shown that at the DNA-level there is no difference with Scolioneura betuleti. Probably both species will have to be synonymised, in which case the oldest name, viz. betuleti, will be the valid one.
