Tachyerges pseudostigma (Tempère, 1982)
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).
Betulaceae, Salicaceae; narrowly polyphagous
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).
Rhynchaenus stigma: Hering (1957a), Scherf (1964a) a.o.
The species only relatively recently has been split off from T. stigma, and older records of phenology and hostplants therefore are unreliable.
