Description: 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.
