Meet Camponotus festinus: Large Southeast Asian Carpenter Ant!
Why Camponotus festinus?
Camponotus festinus is a large tropical carpenter ant from Southeast Asia (type locality Sarawak, Borneo). Polymorphic brown-to-black workers and a bulky queen create an impressive colony that nests in hollow stems and rotting wood.
