There is a colony of black ants that has a nest in our side yard. We frequently see them coming from the parking strip outside of our house carrying leaves with them to store for their food. They are especially busy before a rain storm comes. They are a good warning sign to be prepared for the rain. They are also a great example of industriousness. Under each green leaf is one single ant carrying what has to be close to an equivalent of its own weight. It doesn't stop. There are always other ants ahead of, behind, or to the side of the one carrying the leaf. Perhaps they are cheerleaders but we like to think they are typical laborors here in Corrientes: one working and a few gathered around watching.
