Oecophylla smaragdina , commonly known as semut rangrang in Indonesia, is a species of arboreal ant that is a member of the subfamily Formicinae. This species is commonly observed in all parts of Indonesia. They build nests on tree leaves and develop into large colonies.
I noticed something intriguing about this ant yesterday. For one ant, two ants are fighting each other. Whether the ant that became prey is still alive or has turned into carrion is unknown to me. The two ants do engage in cannibalism against other members of their own species.
Another colony of ants has engaged in a fight for prey only a few inches away from them. However, the prey is bush cricket. Their powerful and sharp jaws continually pull at their prey.
This is a typical occurrence in the ant kingdom. What about the act of cannibalism, though? To be really honest, this is the first I've ever seen.
