Please watch our new video on youtube. It was casted with a simple smartphone lens. The video shows an ant, which is eating from a drop of honey.
The parts of the ant´s body are very clearly to see. Even the movement of the jawbone, while he soaks up the honey.
During eating, the ant is hitting the floor with his rump. This is a way of communication between them. He probably tries to inform the rest of the colony, that he found a rich food source.
Another way is to leave a scent mark. This leads other ants in his direction and they would begin to leave additional scent marks. Thus, they establish a route, on which the traffic will increase steadily.
