The Silver Arrowhead or Hooked Copper (''Phasis thero'') is a butterfly of the Lycaenidae family. It is found in South Africa. The wingspan is 31–46 mm for males and 38–47 mm females. Adults of ssp. ''thero'' are on wing from September to November and again from March to May in two generations. Adults of ssp. ''cedarbergae'' are on wing from October to November and probably also in autumn.〔Woodhall, S. Field Guide to Butterflies of South Africa, Cape Town: Struik Publishers, 2005.〕 The larvae feed on ''Rhus undulata'' and ''Melianthus major''. Larvae have been found inside hollow stems of their food plant, but also in nests of ''Cremogaster peringueyi'' ants at the base of these stems. ==Subspecies== *''Phasis thero thero'' (from Cape Peninsula, north along coast to Lambert’s Bay, east to Knysna) *''Phasis thero cedarbergae'' Dickson & Wykeham, 1974 (Cederberg and Gifberg) 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「Phasis thero」の詳細全文を読む スポンサード リンク
