First Occurrence of Cheilomenes sexmaculata (Coleoptera: Coccinellidae) on the Caribbean Island of Curaçao


The predatory ladybird species, Cheilomenes sexmaculata (Fabricius), is native to Asia and Australia but has established populations outside its native range, most recently on the eastern and northern coast of South America. Here, we report for the first time the identification of the introduced ladybird beetle, C. sexmaculata, to the Caribbean islands, specifically the island of Curaçao. Although C. sexmaculata is typically considered beneficial and used as a means of biological control in continental ecosystems, due to its high predatory and reproductive ability, it has the potential to cause major ecological impacts as an invader to sensitive Caribbean island ecosystems.
