The Scarce Black Arches (''Nola aerugula'') is a moth of the Nolidae family. It is found in most of Europe, east to eastern Asia and Japan. It is a rare migrant to Great Britain. The wingspan is 15–20 mm. Adults are on wing from June to August in one generation. The larvae mainly feed on ''Trifolium'' and ''Lotus corniculatus'', but also ''Betula'', ''Salix'' and ''Populus'' species. The larvae of ssp. ''holsatica'' feed on ''Genista anglica'' and ''Genista pilosa''. Larvae can be found from August to June. They overwinter. Pupation takes place in a cocoon which can be found on the ground or attached to the host plant just above the ground. ==Subspecies== *''Nola aerugula aerugula'' *''Nola aerugula holsatica'' Sauber, 1916 (Denmark, the Netherlands) Many authors consider ''holsatica'' to be a full species. 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「Nola aerugula」の詳細全文を読む スポンサード リンク
