Parasitic Acacia Ant

A cheater species that occupies acacia thorns but provides little defensive benefit to the host tree. Unlike mutualist acacia ants, it does not attack herbivores or clear competing vegetation.

💡

Did You Know?

It exploits the mutualism by taking food from the acacia without reciprocating with defense, essentially freeloading.

Spiny Ant

A distinctive Asian ant with paired spines on the petiole and propodeum. Workers are metallic dark brown and build nests from silk produced by larvae, similar to weaver ants. Colonies are arboreal and highly territorial.

💡

Did You Know?

They are commonly eaten as a protein-rich food in parts of southern China, where they are harvested from silk nests in trees.
