''Pancalia leuwenhoekella'' is a moth in the Cosmopterigidae family. It is found nearly all of Europe.〔(Fauna Europaea )〕 In the east, the range extends to Asia Minor, the Caucasus, south-western Siberia and the Russian Far East. The wingspan is 10–12 mm. Adults are on wing from April to June.〔(UKmoths )〕 The larvae feed on ''Viola'' species, including ''Viola tricolor'', ''Viola hirta'' and ''Viola canina''. They initially mine the leaf stem of their host plant. In this stage, frass is ejected out of the mine through a hole. Later, the larvae feed on the bast fibre of the subterranean parts of the plant from within a silken tunnel. Pupation takes place in a cocoon made of silk and covered with sand.〔(microlepidoptera.nl )〕 ==Subspecies== *''Pancalia leuwenhoekella leuwenhoekella'' *''Pancalia leuwenhoekella japonica'' Riedl, 1973 (Japan: Honshu) *''Pancalia leuwenhoekella mandshuricella'' Sinev, 1985 (Russian Far East) 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「Pancalia leuwenhoekella」の詳細全文を読む スポンサード リンク
