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 undistinguishable from those of S. vicina, 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 payrifera, pendula, pubescens.

phenology

Larvae from mid May till mid June.

BENELUX

NE Recorded (Ellis, not rare).

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

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.
