The geranium bronze or brun des pélargoniums in French (''Cacyreus marshalli'') is a butterfly in the family Lycaenidae. The wingspan is 15–23 mm for males and 18–27 mm for females. Adults are on wing year round in warmer areas, but usually from August to May in South Africa. At higher altitudes adults are on wing in December and January.〔Woodhall, S. Field Guide to Butterflies of South Africa, Cape Town: Struik Publishers, 2005.〕 It is brown with a fine black edge interlaced with white and a very thin tail. The underside is grey-brown with dark bands. The caterpillar feeds on cultivated ''Pelargonium'' geraniums, as well as on species of the related ''Geranium'' genus. The species is native of South Africa. It has, however, been introduced (deliberately or accidentally) to Mediterranean Europe (initially the Balaeric Islands), where it has spread as a pest of cultivated ''Pelargonium'' geraniums, which also originate in South Africa. It was first recorded in the United Kingdom in Sussex in 1997 (also on geranium), and has been recorded several times since. In the UK, all sightings should be reported to DEFRA. It appeared in Malta on March/April 2007. The first location that established itself was at San Gwann but in a few months took all over the island. Recently it has also been spotted in Mġarr, Xagħra, Gozo and in Katerini. ==Gallery== File:Lycaenidae - Cacyreus marshalli-1.JPG|Imago, underside File:Lycaenidae - Cacyreus marshalli.JPG|Imago, underside File:Cacyreus marshalli 01 by-dpc.jpg|Imago,upperside File:Cacyreus marshalli larva02.jpg|Larva File:CacyreusMarshalli.jpg|Two caterpillars inside a geranium stem 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「Geranium bronze」の詳細全文を読む スポンサード リンク
