Antingy

Antingy refers to the practice of rubbing ants on one's skin, often to ward off insects or to alleviate itching. This behavior has been observed in various animal species, including primates. The ants, typically formic acid-producing species, are believed to deter biting insects like mosquitoes. The formic acid itself may act as a repellent or have a mild anesthetic effect on the skin.

While the exact evolutionary reasons for antingy are not fully understood, it is thought to be a self-grooming behavior that provides a form of natural pest control. Some researchers suggest it could also be a way for animals to acquire or spread beneficial microorganisms from the ants to their fur or feathers. The practice is generally short-lived, with the animal quickly discarding the ant after rubbing it over its body. Observations of antingy have been documented in chimpanzees, gorillas, and various bird species. In some cases, it has been observed as a playful behavior in younger animals. The scientific study of antingy continues to explore its ecological and behavioral significance.
