Jumping sickle ant is a social insect, and they communicate with each other through pheromones emitted by their bodies. When jumping ants find food, they will spread pheromones on the food, and other jumping ants will instinctively drag things with pheromones back into the hole.
Pheromones still exist after ants die, and other ants will be attracted by them when they pass by, but dead ants will not exchange information with each other (touch their tentacles) like living ants, so their pheromone-bearing bodies will be taken back by their companions as food.
Under normal circumstances, such a corpse will not be eaten as food, because apart from pheromones, every nest of jumping ants has its own specific smell, and things with the same smell will not be attacked, which is the basis for jumping ants in the same community to cooperate well.
Indian jumping ant
Indian jumping ant is one of the earliest ant species with gene sequence in ant community. They are very social insects, and they can communicate with each other through pheromones emitted by their bodies. They spread pheromones on the food they find, and other ants will instinctively drag things with pheromones back to their holes.
This pheromone can last for a long time, even after the ants die. The pheromones on dead ants will attract passing ants, so soon there will be companions carrying back the bodies with pheromones as food.
And under normal circumstances. Dead ants don't have to worry about being eaten as food. Because in addition to the fixed pheromone, each nest of ants will also have its own specific recognition smell, which is usually friendly to companions who smell the same as themselves and will not attack.
