There are several things I have noticed that the ants do when they collect food: If it is a liquid, they will hold on to the lip of the dish with their back legs, and drink the sweet substance. The three armor-like plates on their abdomen swell as the ants drink. There are transparent folds of skin-like material in between the plates. (You can see this in the picture.)
The ants that have been collecting food will feed newcomers some of whatever they have collected. I think this is so the newcomer can see the type of food she is supposed to collect. I don’t know this for sure, but it seems like the ant will go directly to the dish that contains whatever she has been given, and no other.
There is a predator for the ants, the pallis. They are little geckos that come out at night and eat bugs. The pallis have found the spot where the ants come to get fed. You rarely see pallis beyond three inches but pallis that eat our ants are five or six inches. They are being fed ants that are large already but are made even larger by the sweet nourishment they are bringing back to the nest. The food these pallis eat are both nutritious and and filling. Pallis eat as much as they can and the ants are so consumed with their work that they don't even realize that the pallis are there. The pallis are able to eat quite a bit, and they get really big.
