The Clidemia thrips, Liothrips urichi, is a thrips species from Trinidad. It is used as a biological control agent to stop the spread of Clidemia hirta (Koster's curse), an invasive plant species that does much damage in many tropical areas of the world. Infested tips of C. hirta may contain all stages of L. urichi but larvae tend to cause the most damage. The thrips can control mature C. hirta by attacking young succulent growth causing tip die-back.
