 Notes on identification. MUCHE (1969a) provided a detailed description of the adults. This species differs from the similar S. baikalensis by an extensive colour pattern on the abdomen, with orange-yellow marks extended laterally and thus merging with yellow spots on laterotergites; the abdomen of males is mostly orange yellow. Male genitalia as in Fig. 14. The larva was described by LORENZ & KRAUS (1957). It differs from the larva of S. baikalensis by a uniformly green ground colour without mottling. The host plant in Central Europe is also different (see below).   
 Bionomics. Univoltine. Flight period from late April to mid June; larval period from May to June. Host plants: Dryopteris (= Aspidium) spp., Dryopteris carthusiana, D. dilatata, Polystichum (Dryopteridaceae), Athyrium filix-femina (Woodsiaceae), Pteridium aquilinum (Dennstaedtiaceae) (TAEGER et al. 1998) and Arachnoides miqueliana (Dryopteridaceae) (NAITO 1996). I collected the larvae exclusively on A. filix-femina.   
 Distribution. Holarctic Region (Central and Northern Europe, Siberia, China, Japan, Korea, North America) (NAITO 1996). Scattered occurrence in the Czech Republic from uplands to highlands.
