Host plants: Salix capera Linn.  and Salix  spp. ( Salicaceae  ) ( Friese 1969, Agassiz 1996).

Distribution. China (Gansu, Xinjiang), Europe, Russia, America, Canada.

Diagnosis. Argyresthia (A.) pygmaeella  superficially resembles A. (A.) brockeella  (Hübner, [1805]); the two share a forewing with golden streaks. The two species differ remarkably in features of the male genitalia: A. (A.) pygmaeella  has a subrectangular valva, a subtriangular saccus obtuse apically, and coremata ( Fig. 121View FIGURES 120 – 125); A. (A.) brockeella  has a subovate valva narrowed at the base and widened towards the apex, a band-shaped saccus nearly uniform in width, and lacks coremata ( Fig. 122View FIGURES 120 – 125).
