Tachyerges pseudostigma (Tempère, 1982)

mine

Full depth corridor, beginning at the base of the midrib and very roughly following the leaf margin; all the while the corridor widens, until almost the entire leaf has been mined out. Frass, as coarse grains or thread fragments, in the centre of the mine. The larva pupates in the mine, in a globular cocoon made of secretion (Scherf, 1964a).

host plants

Betulaceae, Salicaceae; narrowly polyphagous

Alnus; Betula; Corylus avellana; Populus nigra; Salix alba, cinerea subsp. oleifolia, repens.

BENELUX

BE recorded (Delbol, 2009; Curculionidae.be, 2010).

NE recorded (Edzes & Heijerman, 2008a).

LUX not recorded (Fauna Europaea, 2007).

distribution within Europe

Entire Palearctic (Dieckmann & Tempère, 1984, cit. Morris, 1993a).

synonyms

Rhynchaenus stigma: Hering (1957a), Scherf (1964a) a.o.

notes

The species only relatively recently has been split off from T. stigma, and older records of phenology and hostplants therefore are unreliable.
