Scolioneura betuleti: mines on Alnus viridis

Alnus viridis, Scotland, Orkney @ Derek Mayes

Scolioneura betuleti: larva

larva

mine

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

hostplants

Betulaceae, oligophagous

Alnus viridis; Betula alleghaniensis, ermanii, humilis, obscura, 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

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).

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

notes

Especially numerous on seedlings.

references

References before 1998 refer to betuleti + vicina.
