Farmer ants and their aphid herds
www.westcoastseeds.com
Several species of ants have a special symbiotic relationship with aphids- they farm them! Aphids feed primarily on the sap from plants and secrete a liquid called honeydew. This secretion is very sugar-rich, and quite favoured by ants as a food source. As a result, a system has been hashed out by these insects wherein the ants herd the aphids around to the juiciest parts of plants, protect them from predators, and carry them into their nests at night and for winter. In return they are allowed to ‘milk’ the aphids- stroking the aphids with their antennae, coaxing them to secrete their honeydew which is then lapped up by the ant. In every species of ants, workers will specialize in different roles such as nursing or foraging to fulfill the needs of the colony - in farming ants, some workers will specialize just in shepherding and caring for the aphids! There's even some evidence that ants build pastures of a sort, to keep their herded aphids in. When the colony departs one nest site to form another at a new location, they will carry an aphid egg with them, to establish a new herd and maintain their resources. If you are wondering what all the fuss for honeydew is about, you should know that many areas of the world, most notably Germany’s Black Forest, actually tend bee colonies that collect and make honey from honeydew, resulting in a stronger tasting, darker product. Ants certainly are the world’s oldest, and smallest, farmers. Click here to watch some footage of this process. @AdaMcVean

    And, youre aware of the depth of ant cognition… How? Exactly?

      Insect cognition has been a researched topic for some time. Most people tend to reduce them to some robotic form of being, I think that’s not the case as does more modern research. They are capable of learning, bumblebees have been observed displaying playful behaviour (or at least something that resembles it). However all evidence still suggests that their behaviour is very much governed by instincts and can be predicted quite well. There are no known intellectual abilities of insects that come close to those of somewhat intelligent vertebrates. Humans and primates are in another category altogether.
