Species of moth
Glyphipterix forsterella is a moth of the family Glyphipterigidae. It is found from most of Europe (except most of the Balkan Peninsula, Portugal and Ukraine),[1] east to Japan.
The wingspan is 11–15 mm (0.43–0.59 in).[2] The forewings are rather broad, dark bronzy - fuscous; five white streaks from posterior half of costa, second becoming silvery-metallic and reaching beyond middle; a broader slightly curved oblique white mark from middle of dorsum, reaching half across wing a short white mark before tornus; two or three silvery-metallic dots about tornus; a black apical spot enclosing a silvery- metallic dot; dark line of cilia indented below apex; a dark hook above apex. Hindwings are grey.[3]
Adults are on wing from May to June and feed on the flowers of the larval host plant.[4] There is one generation per year.
The larvae feed on the seeds of Carex species, including Carex vulpina[5] and Carex remota.[6] The species overwinters in the larval stage within the spikes of the host plant.[7]
