The ant complained of losing the path. This was an accurate depiction of observed ant behavior. The smallest Argentine ant workers become nurses. They care for the eggs, larvae, pupae, and young ants. Other workers have jobs such as slave-making, where the ants sneak into other ant colonies and steal eggs.
Workers also herd and milk aphids.
All workers generally live about four years. Colonies may consist of hundreds to thousands of members. If one ant does not do its job, the other ants will suffer from that ant's lack of responsibility. New colonies form from older ones. This is called budding.
