What does the antenna on the ant's head do?

A pair of antennae on the ant's head are important sensory organs. Because there are many tiny holes on the antenna surface, some of which contain cells that can feel the smell. The antenna is always in motion, sometimes twisted and sometimes rotated. Don't dare to bite food until it is "examined" by tentacles. The antenna can tell ants about sound waves, taste, smell, humidity, temperature, etc., and can also let ants distinguish between dilute sugar water and clear water. The information transmitted by the antenna and other information systems complement each other to form a relatively complete communication system, which enables small ants to gather into a huge group and complete many tasks beyond individual ability. If the tentacles of ants are removed and put back into the original ant colony, they will pounce on their companions because they lose their sense of smell and can't smell their companions, and bite each other when they meet.
