Ceroplastes japonicus (Green) is a new insect species in Croatia. Identification of C. japonicus was confirmed for the first time in 2006., but plant material for this identification was collected in 2005. which was slide mounted. First record of C. japonicus was in Novigrad in Istria on Laurus nobilis, but later we identified species at many other finding places in Istria on many different hosts. We noticed mass outbreaks of C. japonicus in 2005. and 2006. During monitoring in 2005. and 2006. this species was found only in Istria, but nowhere else. Along the rest of Adriatic coast, we recorded mass outbreak of species Ceroplastes rusci which is present in Croatia for a long time. C. japonicus was for a long time misidentified and confused with C. rusci. Goal of our investigation was to distinguish this two species, make a list of host plants and a map of its distribution in Republic of Croatia.
