Why do ants farm aphids



An example of mutualism in nature, ants stroke their aphids' antennae and lap up sugary liquid called honeydew.

Aphids create a sweet liquid called honeydew. Ants love it! They even farm it.

 

Gavin Broad: Some ants run the insect equivalent of dairy farms. A bit like cattle farmers, they keep herds of sap-sucking aphids. The ants move their aphids to the juiciest parts plants protecting them from predators such as ladybirds. In return, the ants milk the aphids for honeydew, the waste product of their diet, by stroking them with their antennae and lapping up the sugary liquid as it`s secreted. Ants and aphids both benefit from this relationship, making it an example of mutualism. Humans first domesticated plants and animals 10,000 to 15,000 years ago. However, ants have been farming aphids and fungi for millions of years.

 

Emily Osterloff: Millions of years that is incredible! Gavin and I actually had a bit more of a chat about ants, aphids and mutualism, and you can watch that over here.
