If you think the answer is only people , then you are wrong. Ants can do all those things too. Leafcutter ants use the leaves they cut from plants to grow underground fungus gardens. Many types of ants take care of herds of aphids, even taking a few under ground in the winter and returning them to plants in the spring. A few species of ants herd caterpillars, taking them into their nest each night and leading them back up into nearby trees in the morning.
Ants are responsible for planting many wildflowers in New England and other areas.
The wildflower seeds have special structures on them that serve as ant food. The ants peel off the structure and throw the remaining, still viable seed into their refuge heap, planting it for the next season. Finally, fossil hunters know to look for harvester ant mounds because the ants often dig up and discard tiny fossils. Since ants do all those things, it s not surprising that people love to watch ants in action. Ants may be interesting to us because they are so different from people, yet do so many similar things.
