The Polyrhachis lamellidens, commonly known as the “Large Fish hook Ant,” is the crown jewel of East Asian spiny ants. Native to Japan, Korea, and China, it is famous for its massive, backward curving spines and its beautiful metallic luster. However, what truly sets this ant apart isn’t just its “armored” look, it’s its incredible and brutal lifestyle. Unlike most other spiny ants, P. lamellidens is a temporary social parasite.
