Why do ants 'milk' aphids?
|
 | | Ants in the process of 'milking' a group of aphids |
Aphids are tiny insects commonly seen during the summer months. They feed on plant sap and produce a sugary secretion called honeydew. Ants pay frequent visits to the aphids to collect this liquid, and often encourage them to produce more by touching them with their antennae. This behaviour is called 'milking'. In return for a rich supply of food, the ants protect the aphids from insect predators.
