First record of alien species Chymomyza amoena [Diptera, Drosophilidae] in Croatia.
The alien species Chymomyza amoena (Loew 1862) is recorded in Croatia for the first time. This phytophagous drosophilid native to North America was first discovered in Europe in 1975 in the former Czechoslovakia. C. amoena breeds in parasitized fruits and nuts damaged from primary pest attack. It is considered to be the principal drosophilid with this kind of developmental habits in both North America and Europe. The currently known host plants, species morphology and biology, the location of the first finding and possible ways of expanding in the territory of Croatia are briefly reviewed. This work provides new insights into distribution of C. amoena in Europe.
