Contribution to knowledge of the distribution of the Geranium Bronze Cacyreus marshalli (Butler, 1898)(Lepidoptera, Lycaenidae) in Croatia with note on ecology and ethology

The species Cacyreus marshalli was introduced into Europe from South Africa in 1978. In Croatia its presence was noted for the first time in 2009 in Mali Lošinj. Previous research has recorded this species at around 20 localities. The present paper gives new records of the species Geranium Bronze from 28 localities in the Mediterranean part of Croatia with some data regarding its ecology and ethology. The known margin of the distribution area of C. marsahalli in Croatia has expanded by around 50 kilometres to the south-east to the islands Korčula and Lastovo and in inland to the Pelješac peninsula. The Geranium Bronze has not been recorded in the continental and central mountain part of Croatia, but was for the first time recorded on Mt. Učka, on 934 meters a.s.l.
