The reproduction of the aphids is carried out in good conditions, because the reproducing females are kept in underground chambers where the eggs are sheltered during the winter. The ants eat the aphids’ honeydew, their excrement, which is rich in sugars and other organic molecules derived from the sap of the plants they have ingested.
