''Trifurcula subnitidella'' is a moth of the Nepticulidae family. It is widespread in Europe southward to the northern border of the Sahara in Tunisia and eastward to the Crimea and Asia minor. The wingspan is 4.2-5.8 mm for males and 4.4-5.4 mm for females. Larvae have been found in September and October and adults are on wing from May (March in Tunisia) to early September. The larvae feed on ''Lotus corniculatus'' and possibly other ''Lotus'' species. They mine the bark of their host plant. The mine consists of a long gallery in the bark of the stem. The larva first mines down, then goes up the stem in a rather straight line, or partly encircling the stem, occasionally going down again in the last part of the mine. At first, the mine is narrow, reddish brown, with straight edges, but later becomes as wide as the stem, with irregular margins, becoming silvery white in fresh mines. The frass is brown and deposited in a central line. Pupation takes place outside of the mine. ==External links== *(The Trifurcula Subnitidella Group (Lepidoptera: Nepticulidae): Taxonomy, Distribution and Biology ) *(Fauna Europaea ) *( Swedish moths ) Image and Swedish text *( Figures of genitalia ) 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「Trifurcula subnitidella」の詳細全文を読む スポンサード リンク
