Abstract

Butler, 1898) is the only butterfly introduced (non-native) into the European fauna. It was introduced in 1988 on the Balearic Islands fromwhere it spread across Europe.

Materials andMethods:Cacyreusmarshalli observationswere conducted
during the day at all locations. At a number of localities, geraniums as
larval host plants were inspected to determine the presence of C. marshalli caterpillars.

Results and Conclusions: In Croatia, C.marshalli first appeared on the
island of Lo{inj. The paper presents new distribution data for the Geranium Bronze and its expansion across Croatia (all in theMediterranean area) and discusses possibilities of spread due to climate change. Further systematic monitoring of spreading of C. marshalli in Croatia is necessary for it to be assigned to changing climate and above average temperatures in the last years, in particular since 2000.
