improba (Butler, 1877)

Dusky-winged Fritillary (ENG), kääpiöhopeatäplä (FIN), dvärgpärlemorfjäril (SWE)

The host plant is clearly Salix herbacea, as anticipated already by Bruun & von Schantz. Populus tremula and, of course, several species of Salix were accepted in confinement without any problem. It hibernates in the second instar.
