Ants have good communication skills and highly social insect. Ants live in big colony they have perfectly organized system. Have you seen before ants are go in straight line from your home or up the wall. And do you think why? Let's know about that here.

This video about how do ants walk in straight and while they hit eachother!

When worker ants leave the nest to find food they leave behind a chemical scent that's called PHEROMONES. So colony mate follow this scent the leader left behind, that's why they make straight line and which helps the other ant reach food source easily. 

But every colonies has not same smell of scent, each colony has a distinctive smell of scent. If two ants hit they smell the scent of each other, and the scent doesn't match they easily find outsiders enter into our colony.  So they start to attack. But if the scent belong to the same colony then other ants follow the smell and return their colony after finish their work.

Why they kiss each other? When they find food colony mate kiss each other while walk in straight line.  They are not only smell scent while hit and also they talk each other.  If you ask what they talk? Not a big stories, Just talk simple messages like where is foods? Where are enemies located? and identify their colony mates.

Now pheromones evaporate quickly after finishing work and before enter their colony.
