Description: Crematogaster rogenhoferi builds cardboard nests pronounced in the trees of Southeast Asia. The nests have an average height of 2.5 to 4.5 m and a length of 22 cm and a width of 10 cm. This species is called "nesting in the woods" or "lignicol" (which lives in the woods) or ant "acrobat" because they defend themselves by a particular means. Indeed they have the ability to raise their abdomen over their heads and bead (create) at the end of their sting a droplet of venom containing acetic acid. Vaporized acetic acid plays an alarming role: the worker who emits venom warns other workers of a danger. The period between the laying and the appearance of the worker being long it will be necessary to wait for the first fortnight of workers to see growth accelerate. They all have an abdomen in the shape of ace of spades. This wood ant raises aphids (in the wild) to feed on sweet liquids.

Foundation: Set in a cloister (without food) Development: 30 days from egg to worker (depending on temperature)

Size of the colony: A few hundred individuals, the queen can reach the age of 12 years.
