Self-Sacrificing Ants Refuse Treatment of Their Wounds | National Geographic

A new study reveals that after a raid on a termite nest, the injured [Matabele] ants are cared for by their comrades.
Navy Seals abide by a code that no man is left behind. Termite-hunting ants abide by a similar code. A new study reveals that after a raid on a termite nest, the injured ants are cared for by their comrades.
If kept by themselves, 80 percent of injured ants died. But if cared for by their nest-mates for even an hour, only a tenth died.
Another finding of the study reveals how the ants prioritize who gets cared for and who doesn’t. In human health care, doctors decide which patients need to be helped the most. With ants, it’s the exact opposite. The injured ants themselves decide if they should be treated or not.
When no help was in sight, injured ants made a beeline for the nest. But when nest-mates were near, they stumbled and fell, appearing “more injured” as a way to attract aid. But the ants play up their injuries only if they sensed that their problems were minor enough to be treated. If ants were mortally injured, they refused to cooperate, flailing their legs around when probed or picked up, forcing their helpers to abandon them.
The mortally wounded ants choose to die rather than have energy and resources wasted on their futile rehabilitation. This discovery marks the first time non-human animals have been observed systematically nursing their wounded back to health.

Termites are the African Matabele ants’ (Megaponera analis) favourite dish. Proceeding in long files of 200 to 600, they raid termites at their foraging sites and haul the prey back to their nest where they are ultimately eaten. Before starting their raids, the ants send out scouts to look for the termites’ foraging sites. Once they have spotted them, the scout ants return to the nest to mobilize their comrades. On their way back to the nest, the scouts show astonishing navigational abilities: They take the quickest route rather than the shortest: here.
