''Eugraphe sigma'' is a moth of the Noctuidae family. It is found from most of Europe (except Ireland, Great Britain, the Iberian Peninsula and Greece)〔(Fauna Europaea )〕 to the Ural, Siberia, Transcaucasia, Armenia and Korea.〔(Eugraphe at funet )〕 The length of the forewings is 17–20 mm. Adults are on wing from June to July in one generation per year.〔(Vlindernet )〕 The larvae feed on various low-growing plants, including ''Lamium album'', ''Viburnum lantana'', ''Laburnum anagyroides'', ''Prunus spinosa'', ''Lonicera'' and ''Ligustrum'' species. Young larvae live in the top parts of the host plant. The species overwinters in the larval stage. After overwintering, the larvae hide during the day and feed on the terminal part of the twigs during the night. Pupation takes place in the ground. ==Subspecies== *''Eugraphe sigma sigma'' *''Eugraphe sigma melancholina'' Bryk, 1949 (Korea) *''Eugraphe sigma anthracina'' Boursin, 1954 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Eugraphe sigma」の詳細全文を読む スポンサード リンク
