Notes on description:
Specimens from northern DDR and alpine localities (1100-2000 m) in southern Poland and Austria differ markedly (Fig. 2) from the west European specimens as described above. The alpine form, described as a distinct species (arifoliella Klimesch) is larger, 4-5 mm, with more contrasting wing-pattern: a broad band before fascia and distal part of forewing almost black, suffused with blue and violet; the fascia is broad, silvery. The head black. Host plant Rumex arifolius. A long series of specimens from northern DDR show little or no difference from the alpine ones. Breeding experiments (Borkowski, 1975: 529) have shown that the alpine form feeds on Rumex acetosa as well. The genitalia show no differences from those of west European specimens.
