Dryopteris
:''The moth genus ''Dryopteris'' is now considered a junior synonym of ''Oreta. ''Dryopteris'' ,〔''Sunset Western Garden Book,'' 1995:606–607〕 commonly called wood fern, male fern (referring in particular to ''Dryopteris filix-mas''), or buckler fern, is a genus of about 250 species of ferns with distribution in the temperate Northern Hemisphere, with the highest species diversity in eastern Asia. Many of the species have stout, slowly creeping rootstocks that form a crown, with a vase-like ring of fronds. The sori are round, with a peltate indusium. The stipes have prominent scales. Hybridisation is a well-known phenomenon within this group, with many species formed by this method. ==Ecology== ''Dryopteris'' species are used as food plants by the larvae of some Lepidoptera species including ''Batrachedra sophroniella'' (which feeds exclusively on ''D. cyatheoides'') and ''Sthenopis auratus''.
